Eureca USB camera boards for linear sensors

Eureca offers a new family of USB line scan camera boards from its own production, based on the TCD1304DG linear sensor from Toshiba. Due to their small size, they are ideal for building compact optoelectronic measuring devices. A high line rate and a wide range of possible exposure times enable use in a variety of applications. The low price also makes these modules interesting for research, teaching and the maker scene.

Possible applications are:

• Spectroscopy / Spectrometry
• Edge detection
• Position control
• Measuring objects
• Scanning documents

We present some applications in more detail on a separate page.

A page with answers to possible questions (e. g. »How does … the operation of several line scan cameras on a single control computer actually work?«) is currently under construction.

Line scan camera modules

The modules of the line scan camera family are available in two basic versions.

STD: Standard Version

This version offers a balanced price-performance ratio and is suitable for a variety of applications and different measuring tasks.

PRO: Professional Version

This version offers additional features such as an external trigger for demanding measurement tasks with lower tolerances. This significantly extends the possible uses.

Common values include:

• Read out noise: 45 e⁻
• min. Exposure Time: 0.01 ms
• Maximum data rate via USB: 2 MB/s
• Supply current: < 250 mA

!!! Currently under development: e9u-LSMD-TCD1304-EDU !!!

With the EDU version of our proven line camera modules, we are introducing a particularly cost-effective alternative on the market: without FPGA, but full functionality for typical educational applications. Instead of complex hardware logic, a microcontroller handles the USB data transfer—making it ideal for teaching labs, STEM projects and anyonewho wants to make spectroscopy understandable and affordable, for example.

Despite being slightly slower than the STD version, the EDU variant impresses with reliable data quality, simple integration and an excellent price-performance ratio.

The first prototypes have already been built and are ready for testing.

Line scan camera modules Open Source (OS)

Among other things the line scan cameras were developed as part of the Optocubes research project (open source modular system for agile prototyping of laser-based sensors) [Forschungsprojektes Optocubes (Open Source Systembaukasten für das Agile Prototyping laserbasierter Sensoren) – german only], which is funded by the Federal Ministry of Education and Research (BMBF).

Easy control

A special »EasyAccess« DLL is available for our USB line scan camera modules, with which the cameras can be put into operation very quickly and controlled for simple applications.

The initialization of the camera, the recording as well as the transfer of the acquired sensor data is done with a few simple commands. This makes this DLL ideally suited for use with Python, but also with other programming languages. Our application examples for our line scan cameras, for example, were all realized with this »EasyAccess« DLL.

For more demanding, time-critical applications, the »EasyAccess« DLL naturally still contains all the conventional functions for controlling the line scan camera for programming with e. g. C++ or similar. The »EasyAccess«-DLL is available free of charge on request. Please contact us via e-mail if you are interested.

We have summarized details on this and other scripts on a separate page for controlling the line scan cameras.

From now on, our self-developed line scan cameras with USB connection can also be ordered in small quantities by end customers via our brand new Maker Shop!
