A number of OtO Photonics' spectrometers have been optimised for NIR applications.


SideWinder Series

SW LogoSideWinder series spectrometers are specifically designed for NIR & SWIR detection with options for 900-1700nm and 900-2500nm and a choice of 128, 256 and 516 pixel linear InGaAs sensors with options for one- and two-stage TE-cooled sensors.


SideWinder spectrometers are compact Czerny-Turner designs yet achieve resolution of 4.1nm FWHM over the full 900-1700nm range and 15nm over 900-2500nm.


High-performance 32bit RISC microcontrollers, along with the company's exclusive DTE (Dynamic Thermal Equilibrium) technology and stray light elimination technology (Stray Light Calibration Algorithm) ensure accuracy, speed and stability at very attractive pricing.

The PocketHawk-NIR is the latest addition to OtO's range of crossed-cavity Czerny-Turner spectrometers.


PocketHawk-NIR is offered with a choice of 2 InGaAs sensors covering a spectral range of 900-1700nm with FWHM resolution from 5nm to 30nm - depending on the choice of sensor and slit.


The PH25x4 is very compact for its performance at just 65x65x30mm³ (<127cm³), including the removable external control board.

RS Back TX


The RedSparrow-1680 (RS1680) is OtO's NIR MEMS grating-collimator microspectrometer featuring a 128-pixel NIR InGaAs sensor for operation from 950nm to 1700nm with a FWHM Resolution of 8-13nm.


The RS1680 is incredibly compact at just 40x40x18mm³ (<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.

SE Logo


The compact SE-2050 offers the best SNR in the 790-1010nm range using a linear CCD type sensor (Sony, Hamamatsu, Toshiba) and high performance 32-bit RISC controller.


SE Series spectrometers are based on a Czerny-Turner optical design and provide high optical resolution, high sensitivity, low stray light, and fast spectral response. The optical bench offers excellent rigidity and stability with outstanding resolution and wavelength shift performance.

EE Logo

EagleEye Series

EagleEye-051 (EE2051) is specially designed for NIR and Raman applications with sensitivity from 790-1010nm using a TEC-cooled NIR-enhanced back-thinned sensor, Czerny-Turner cavity and high performance 32bits RISC controller which provide accurate measurement with highly stable temperature control.


The EE2051 can achieve full 180-1100nm operation when used in a long time mode.
