OtO Photonics' RedSparrow-Series is their latest MEMS grating-collimator microspectrometers - bringing the size, performance and cost benefits of their UltraMicro-Series technology to the near infrared band.

 

RedSparrow is incredibly compact at just 40 x 40 x 18mm³ (<30cm³), including the removable external control board, and yet the rigid metal package and optical bench provide excellent thermal, humidity and shock/vibration stability performance.

 

RS1680 uses the Hamamatsu G13913 128-pixel NIR InGaAs sensor for operation from 950nm to 1700nm with a FWHM Resolution of 8-13nm with a 50µm slit. The RS1780 is a new version featuring a 256-pixel InGaAs linear sensor offering improvedFWHM Resolution of 3-7nm with a 50µm slit.

 

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.

The optical input is via an industry-standard SMA-905 multimode fibre connector whilst the externally mounted control board incorporates a 16 bit, 15MHz A/D converter with electrical interface via an external control board featuring a high speed (480Mbps) Micro USB 2.0 connector or 8-pin extension port.

 

OtO's SpectraSmart spectral management software is supplied with RedSparrow and includes a Windows Software Development Kit. Example code for control via Linux is also available upon request.
