We supply a range of high- and ultra-high-resolution spectrometers from OtO Photonics.
These models feature a range of silicon (180-1100nm) or InGaAs (900-1700nm) linear sensors in modified Czerny-Turner cavity designs with a combination of reflective and transmissive components.
Classic Czerny-Turner cavity spectrometers feature a fully-reflective design and offer a number of benefits including high optical resolution and sensitivity, low stray light and fast spectral response:-

OtO's range of high-resolution models replace some, or all, of the collimating and focussing optics and grating with transmissive elements giving fully transmissive (T-T-T or T3) or Transmissive-Reflective-Transmissive (T-R-T) designs:-


Phekda Series - 400-1000nm T-R-T cavity with 2048-pixel CCD or 2048-/4096-px CMOS sensors
Phekda-NIR Series - 900-1700nm T-R-T cavity 512-pixel InGaAs sensor
Merak Series - 830-970nm T-R-T cavity with 4096-pxx CMOS sensor
Megrez Series - 400-1100nm T-R-T cavity with 2048-px back-thinned CCD sensor
Dubhe Series - 800-880nm T3 cavity with Teledyne e2V OctoPlus 2048-px high speed sensor
