OtO's Photonic's UltraMicro Series range of proprietary MEMS-based microspectrometers operate over UV to NIR wavelengths (330-850nm) and are available in form-factors down to just 7cm³.
OtO's MEMS-based microspectrometers replace the "collimator-plane grating-focusing mirror" optical structure used in traditional Czerny-Turner spectrometers with a "non-spherical, mass-producible" micro-sized component which combines grating and focusing functions. The microchip concave grating technology leverages patented algorithms to calculate curvature and ray-tracing to eliminate aberrations and achieve high resolution of 2nm.

All UltraMicro Series microspectrometers have adjustable exposure times from 1ms to 65ms and 2MHz sensor readout rate. They are interfaced via an 8-lead CCD ribbon connector or OtO's optional external control boards with 32bit RISC core and 16bit ADC which provide a USB interface for PC control using OtO's SpectraSmart software. A full Windows SDK is also available - along with example code for Linux operation.
