AP Technologies are distributing OtO Photonics’ new RedSparrow series of MEMS-based grating-collimator NIR spectrometer. RedSparrow is compact (40 × 40 × 18 mm3, <30 cm3) including the removable external control board, and with its rigid metal package and optical bench provides excellent thermal, humidity and shock/vibration stability performance. It has a 128-pixel InGaAs linear sensor and is initially offered with a 50 µm slit offering high sensitivity with FWHM resolution of 8–13 nm over the 950–1700 nm operating range. Communication is via OtO’s optional control board featuring high speed (480 Mbps) USB2.0 or six user-programmable digital I/Os. There is also an 8-pin extension port and 4-pin UART port.
