Founded in the year 1986 by Erwin Schneider the company began its business with small communication adapters. The first production site was the family's kitchen table, but the business grew fast and the kitchen table soon became inadequate. Being familiar with CCD cameras through a former employment it was Erwin Schneider's goal from the start to develop a camera system with new and exceptional features. This plan succeeded through a collaboration with Albert Tröndle and Kay Günther, the first system was presented in 1992 and soon after the first contract was signed with the company ZEISS for use at their transmission electron microscopes.

Since the much too early death of Erwin Schneider in Febraury 1997 the company is being very successfully operated by Mrs. Claudia Schneider and Mr. Kay Günther.

“Persons or institutions cooperating to advance their mutual interests.”


Our clients are our partners, and in order to achieve success it not only takes good ideas but also a profound common basis and trust.


Strong and experienced partners are needed to cover all aspects of an extensive project development in a competent and reliable manner.


The sensors used for digital imaging are of outstanding importance. We have a broad experience with sensors from almost all notable manufacturers.




Digital Imaging and everything connected with it is our special area.
Our CCD Camera Controllers - together with the cameras of our partner company Tröndle Restlichtverstärkersysteme - are installed at Transmission Electron Microscopes (TEMs) in research institutes and universities around the globe and deliver unsurpassed results.

Profound knowledge and a long-standing expertise in diverse areas of electronics technology are the essential foundation for having success in the field of digital imaging.
Of course we're willing and able to apply this knowledge and expertise as well in applications where no image sensor happens to be around...

Control- and Data-Unit

Control for the CMOS detector of a movie film digitizer and processing of the 16 output signals for differential transmission to the downstream processing unit.

Multifunctional PCB

This printed circuit board houses the fan control of the Camera Controller, simultaneously serving the fitting of the fans and the mechanical integration of the module into the tight space above the electronics slots.

Beam-Blanker Interface Module

Slide-in module for the Camera Controller featuring highly configurable control for various types of beam-blanker interfaces at TEMs. Two outputs, two inputs and a comprehensive set of adjustments allow operation even in complex device constellations. All manual settings are being read out and checked for plausibility by the Camera Controller prior to activation.

CCD Sensor Carrier

A 6-layer printed circuit board made of a special material for use in high-vacuum. After soldering the sensor carrier has to be cleaned in a special way to make sure that no impurities occur due to outgassing.

Modern Technologies

The always advancing miniaturization requires the adoption of new assembly methods, as for this high integrated circuit in a BGA package (Ball Grid Array). Its 256 pins are connected to the PCB via solder balls below, using manual soldering is not possible anymore.

External USB-Interface

Designed to adapt older versions of the Camera Controller this little box converts a parallel data interface plus a RS232 interface to USB2.0.

Peltier Control

This Camera Controller module controls the cooling of the camera sensor through a Peltier element. The voltage output is adjustable and galvanically isolated to minimize interference induced by the high currents.

Technology-Mix on the Analog Module

A specialized CCD signal converter in hybrid technology with conventional plug contacts is joined by helper circuits for gain- and offset-control in modern SMD technology.


Modern electronics require lots of connections - data have to be transmitted, other devices have to be controlled and interacted with - and all this fast, small and safe.


It's only about 8 kilometers from our place to the German Space Agency DLR in Oberpfaffenhofen, and we often see their airplanes pass overhead.
Due to this geographical proximity an intensive and fruitful cooperation soon emerged and over the years numerous demanding projects have been realized, mostly within the field of ground based and airborne earth observation.

    PCB Design Perfection starts in the library

    IPC-7351C is the most recent version of a standard for the definition of footprints for SMD-parts (Surface Mount Devices). It's the result of the extensive know-how gathered by the industry over many years of component miniaturization and is intended to ensure optimal producibility.

    For some time we've already followed these rules with newly defined footprints, now all the 'old' components (if going to still be used in the future) will follow.

    The Camera Interface Board supplies all voltages and control signals for the cameras and shutters that run with our Camera Controller.
    Now this board has been one of our longest running designs - so, time for a change! Due to the looming obsolesence of some of the components used so far, and due to several small improvements eagerly waiting to be implemented, we finally decided to make a redesign.
    So, here it is - and as usual attention was also directed towards an easier and more efficient assembly and testing.

    / N E W S /
    Making layouts for electronic boards usually involves significant amounts of manual actions like mouse clicks and keyboard strokes.
    To ease this work and make it more efficient we bought a programmable keyboard (a Prehkeytec MCI 128, used, for 35 bucks at ebay) and adjusted it to our needs by programming the keys with all important commands and macros.
    So everything is set now for an efficient right-hand-only mouse and left-hand-only keyboard way of doing it, and... it works fine!

    / CONCEPT /
    The ever advancing improvements of the CMOS sensor technology slowly but surely make it look interesting for our main application - at Transmission Electron Microscopes.
    The possibilities are now going to be checked in a multistage project leading up to a prototype to be used at the microscope - whereby even upon positive evaluations the possible use will most likely still be limited to the low-end-range, mostly due to the limited dynamic range.
    Nonetheless it's an interesting and fascinating technology!

    / N E W S /
    To improve our internal testing abilities we are now equipped with a new reference Camera-Controller with special, easily accessible plug-in slots for those modules that are particularly critical for achieving an optimal picture quality.

    Critical items like noise level, dynamics, stability, repeatability and interference resistance now can be tested, compared, optimized and documented much easier.

    / STORY /
    No matter how big or small the company, there's one thing that has to be correct and up-to-date: the documentation!

    Equipment, components, tools, work-, production- and testing-procedures, best practices, responsibilities and and and - everything has to be written down in detail. And for every form of styling in text documents or in products - down to the smallest labeling on printed circuit boards - there has to be a style guide definition for all the logos, fonts, colors etc. etc.
    Truly a never ending story...

    In the case of this little, long lived board the closing down of a board producer prompted us to adapt the design to the actual data basis.
    So: define missing parts, draw the schematic, draw the layout, adapt partlist and documentation to be up-to-date - the whole program, but of course in this case that's just a little apprentice piece
    The nowadays available EDA systems simplify tasks like these tremendously - what would one have given for such possibilities one or two dozen years ago... :·)

    / N E W S /
    The time at the turn of the year usually is a bit more silent and we traditionally use it for tidying up and for some rearrange-ments.
    Aside from some upgrades in the IT field we this time concentrated mostly upon our little visitor lounge. It now provides new furnishings and more openness and and is eagerly waiting for the first guests.

    Come in when you happen to be around! For some talking - and maybe a Macchiato Vanilla, a Cappuccino or a Cortado? ;))

    While the development of the USB3-Interface for the CCD-Camera-Controller further proceeds, our existing USB2-Interface receives an update through a modified board. The target of this work is: better producibility, enhanced testability and a further improved reliability.

    The future still offers several possible uses for the USB2 interface - besides in existing applications also whenever the higher bandwith of USB3 simply isn't needed.

    Enhancements - small, but mighty.

    This small adapter board resides in a connector housing of a cable and provides particular adaptations for the beam-blanker-interfaces of diverse TEM devices. The enhancements made cover better electrical connections and mechanical fixtures for the respective cable, and an additional switch, accessible from the outside, which allows the optional inverting of the control signal at the on-site installation.

    The Max-Born-Gymnasium (secondary school) in Germering takes part in the business@school project of The Boston Consulting Group and one of the involved teams asked us for support during phase III, which calls for the development of a business idea.

    Since their idea involves electronics we are able to help a bit - and it's pretty refreshing and fun to be forced to think outside the box for a while... :·)

    / DESIGN /
    Works have begun to integrate a new MCU for the CCD-Camera-Controller.
    It's pretty amazing (and very pleasing), what can be squeezed into such a small space today:
    32bit-CPU, 1MB Flash, 256kB RAM, the operation system plus a plethora of interfaces: Ethernet MAC and PHY, USB2.0 OTG, 8x UART, 4x QSSI, 10x I2C, 2x CAN, 2x ADC, 8x PWM, 15x GPIO, RTC and a parallel databus.

    ...and what's next? :·)

    With the recent redesign of NASA's website it now appears much more fashionably and appealing.

    The presentation of the
    benefits from this as well.

    It shows very interesting photos from the construction of the flying observatory as well as from its operation, including reports about several experiments that have been carried out.

    / N E W S /
    There is a general shift in the image sensor market, away from CCD towards CMOS technology and Sony as a leading technology player adjusts its strategies. CMOS sensors offer several advantages and have become pretty good meanwhile, but due to technological principles CCD sensors with their linearity, homogeneity and high dynamic will continue to be the first choice when it comes to producing the cleanest images in highly demanding applications.

    Here the link to the  > EOL list < 

    / DESIGN /
    USB 3.0 and now 3.1 represent very powerful standard interfaces, and are widely available meanwhile. Most important they offer much higher bandwidths and can deliver significantly more current than earlier versions.

    In addition there is a promising new standard emerging for the imaging industry - USB3-Vision.

    It's time then to give some thoughts to shifting gears.

    Our CCD-Camera-Controllers are deployed worldwide. The regional adjustment to 230V or 115V so far has to be done by hand at the device. In the very near future there'll be an automatic voltage detection and adjustment.

    Oh, and why don't we use AC/DC-modules with a wide input voltage range? Hmm...
    We like AC/DC a lot, but they sure make a lot of noise... ;)

    The top version of our CCD-Camera-Controller will soon get equipped with a capacitive touchscreen. This will allow for a more flexible and clearly arranged presentation of system parameters as well as a considerably more comfortable adjustment of settings at the device.

    Plans for this had been considered for quite a time already, but the solutions offered so far had not really been satisfying.
  • JULY

    The new version of the CPU board for the CCD-Camera-Controller is compatible with the former version, including the main components CPU and FPGA - this is a must due to the required long-term availability.

    At the same time the board will provide the possibility to use other CPUs by the use of adapter boards and thus will offer the path for a step-by-step transition to the next generation with an even more sophisticated timing unit and USB3 on-board.
  • JUNE

    The backplane is the central component of the CCD-Camera-Controller - it establishes the connections between all other components.

    A new revision of the backplane is now needed as part of a long-run strategy to improve the CCD-Camera-Controller. Besides a number of minor optimizations it provides an additional fan interface and adds one SPI channel and some dedicated lines to the display interface in order to accommodate the upcoming capacitive touchscreen.
