We supply compact and ultra-compact high quality spectrometers from OtO Photonics along with their user-friendly "SpectraSmart" spectral measurement software and a range of lamp- and LED-based light sources.
 
OtO offer a range of compact Czerny-Turner cavity spectrometers along with their unique microspectrometers based on innovative Micro Electro Mechanical Systems (MEMS) semiconductor grating chip technology:-
 

SmartEngine Series - world's highest selling and broadest range of compact DUV-NIR C-T spectrometers

HummingBird Series - extra-compact crossed C-T cavity DUV-NIR spectrometers

EagleEye Series - high sensitivity compact TE-cooled DUV-NIR C-T spectrometers

SideWinder Series - compact NIR C-T spectrometers featuring InGaAs sensors for 900-1700nm

UltraMicro Series - 200nm to 900nm MEMS-based microspectrometers as small as 6cm³

 
 
 
 
 
 
 
Classic C-T spectrometers offer a number of key benefits:-

• High optical resolution

• High sensitivity

• Low stray light

• Fast spectral response

 
 
 
 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.
 
Advantages of OtO's MEMS-based UltraMicro "UM-Series" and Advanced-UltraMicro "AM-Series" spectrometers 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.
