SE LogoOtO Photonics' SmartEngine (SE) Series of compact Czerny-Turner spectrometers can be specified with a huge range of configurations based on a choice of:-

 

  • 8 standard sensors
  • 6 standard spectral response ranges (gratings)
  • 6 standard slit sizes

 

For volume opportunities with OEM customers OtO also develop bespoke configurations with custom gratings and slits along with non-standard sensors, optics and interface connections.

 

SmartEngine's standard model numbers and associated sensors are:-

These standard models can be specified with a variety of standard spectral response ranges based on 6 standard grating designs:-

 

DUVN: 200-1025nm, 500 lines blazed at 300nm

FUV: 180-850nm, 600 lines blazed at 300nm

FUVN: 180-1100nm, 300 lines blazed at 300nm - normally used with SE2020

FUVN2: 180-1100nm, dual zone, 300 lines blazed at 250nm/580nm, 70/30 ratio - normally used with SE2060

VNIR: 350-1020nm, 600 lines blazed at 500nm

NIR1: 790-1010nm, 1200 lines blazed at 850nm

 

Standard combinations of sensor and grating (spectral range) are:-
