We supply OtO Photonics' compact and ultra-compact spectrometers using InGaAs linear sensors covering wavelengths of 900nm to 2500nm.
OtO offer a range of compact Czerny-Turner (C-T) and folded C-T cavity spectrometers along with innovative microspectrometers based on Micro Electro Mechanical Systems (MEMS) semiconductor grating-collimator chip technology (RedSparrow, RS-series) or curved-mirror C-T cavity (RedBullet, RB-series).

PocketHawk-NIR Series - low cost 900-1700nm folded C-T cavity mini spectrometers
RedBullet Series - low cost 900-1100nm curved mirror C-T cavity micro spectrometers
RedSparrow - low cost 900-1700nm MEMS grating-collimator micro spectrometers
DragonFly - low cost 900-1700nm, 1250-2050nm & 1340-2280nm InGaAs PD based spectrometers using DLP technology
DualSpectrometer Series - combine SmartEngine and SideWinder for full 180-1700nm or 180-2500nm spectrum
Classic C-T spectrometers offer a number of key benefits:-
- High optical resolution
- High sensitivity
- Low stray light
- Fast spectral response
Variations on the classic Czerny-Turner cavity are used in OtO's folded cavity design (PocketHawk-NIR) and the RedBullet series which replaces the separate collimating and focusing mirror optical elements with a single curved mirror performing both functions.
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.
Advantages of OtO's MEMS-based RedSparrow (330-850nm) microspectrometers include:-
- Small size and low power consumption
- Highly resistant to vibration
- Easy integration into OEM systems
- High volume production with low cost
When combined with OtO’s high-precision optomechanical designs and SpectraSmart software the MEMS grating technology enables microspectrometers which push the performance envelope to deliver the benefits of high accuracy, ultra-compactness, shock resistance, weather resistance and low cost.
