Fit for TOF, FMCW and any wavelengths you shine at it

Fused silica transmission gratings are wavelength continuous and can therefore be used in conjunction with dynamic resolution wavelength schemes. For the same reason, the gratings are suitable for both TOF (time of flight) and FMCW (frequency modulated continuous wavelength) techniques. Gratings can be made for any wavelength range, including 905 nm, 1310 nm and 1550 nm wavelength ranges – samples for prototyping are available.

Non-Mechanical Steering

The grating passively steers each wavelength into a well-defined direction. There are neither macro nor micro-electro-mechanical (MEMS) movements, thus ensuring long-term robustness and stability. Directionality is fundamental and unchanging, significantly easing calibration requirements.

Flat as a 1 mm pancake

Fused silica transmission gratings are flat and thin optical components with high dispersion, enabling compact modules.

Extend your range

Fused silica transmission gratings boast low loss – typically <0.3 dB, furthermore with broad spectral response and great AOI tolerance.

Mass Production Ready

Based on scalable, semiconductor manufacturing processes, fused silica transmission grating production can be scaled to high volume production levels, with unit costs decreasing simultaneously.

Samples

Samples are available for the following wavelength ranges:

940 nm sample
1310 nm sample
1550 nm sample
