Lenses and Filters

Eureca supplies optical and filter solutions for demanding image processing, measurement, and lighting tasks. The range includes lenses from renowned manufacturers (including ZEISS, Kowa, OPTOWL, Qioptiq, Schneider Kreuznach, OPT), interference filters with high transmission, steep edges, and wide blocking, affordable plastic-based IR filters (including in-house cutting service), special linear lenses for scanners and surface analysis, diffractive optical elements (DOE), as well as holograms, chrome masks, and test targets for qualification and calibration. The aim is to achieve reproducible results, clean integration concepts, and clearly documented specifications.

Lenses from leading manufacturers

For machine vision and measurement tasks, Eureca offers lenses from various manufacturers with suitable mounts (e. g., C/CS, F), image circles, and resolutions. The focus is on low distortion, high MTF, reliable imaging performance across the entire field, and options for the extended spectral range. Advice on focal length, working distance, pixel size, illumination, and mechanics ensures that the lens, sensor, and application work together optimally.

Interference filters with steep edges and wide blocking

Hard-coated bandpass, longpass/shortpass, and notch filters with high transmission, steep transitions, and wide blocking are ideal for fluorescence, laser, and multispectral applications. AOI aspects (angle-sensitive CWL shift), substrate selection, tolerances, and mechanical integration (sockets/holders) are supported. Specifications such as OD blocking or CWL/FWHM can be documented on request.

Plastic-based IR filters with cutting service

For cost- and weight-optimized designs, Eureca supplies IR filters made of polymer materials (e. g., as IR pass or VIS block). The in-house cutting service can produce almost any format in a short time. Typical applications include protective windows, sensor covers, and NIR gates.

Line scan / linear lenses for scanners and surface analysis

Specially designed for line scan cameras and high-resolution inspections: Eureca provides support in selection (e. g., sensor width, pixel size, NA), mechanical integration (mounting/focus mechanisms), stray light reduction, and lighting concepts (e. g., line-shaped LED assemblies).

Diffractive optical elements (DOE)

DOE components for beam shaping (top hat, homogenizer), beam splitters, line/cross generators, or vortex functions. Consulting on wavelength range, substrates, efficiency, diffraction order, tolerances, and alignment. On request, combination with interference filters and lenses to form complete beam shaping assemblies.

Holograms, chrome masks & test targets

For setup, calibration, and quality assurance: chrome-on-glass masks, holograms, and test targets (e. g., resolution, distortion, and gray scale targets).

In short: Eureca combines optics, filters, and metrology accessories with application-oriented consulting—from component selection to ready-to-integrate solutions.
