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
  • 7 standard gratings
  • 6 standard slit sizes

 

When specifying the correct configuration of SmartEngine for your application we suggest you start by defining the spectral range and resolution you require - this will enable selection of the appropriate grating and slit. OtO's 6 standard gratings are:-

 

FUVN: 300g/mm blazed at 300nm (normally used with SE2020). 920nm bandwidth for full 180-1100nm

DUVN: 500g/mm blazed at 300nm, 825nm factory-set bandwidth within 180-1100nm

VNIR: 600g/mm blazed at 500nm, 670nm factory-set bandwidth within 180-1100nm

FUV: 600g/mm blazed at 300nm, 670nm factory-set bandwidth within 180-1100nm

NIR1: 1200g/mm blazed at 850nm, factory-set bandwidth of 320nm(UV)/220nm(Vis/NIR) within 180-1010nm

FUV2: 1200g/mm blazed at 300nm, factory-set bandwidth of 320nm(UV)/220nm(Vis/NIR) within 180-1010nm

FUV2A: 1200g/mm blazed at 200nm, factory-set bandwidth of 320nm(UV)/220nm(Vis/NIR) within 180-1010nm

 

These gratings are identified in the table below and you will also find non-standard options. For each grating we show the achievable Resolution over the stated Spectral Bandwidth - thus enabling the combination of Grating and Slit to be identified. When contacting APT please advise the desired wavelength operating range, for example the standard NIR1 grating has a 220nm bandwidth which can be factory set within a 180nm to 1010nm range.

Having established the combination of grating and slit it is then necessary to choose the optimum sensor for your application. OtO offer SmartEngine with 8 standard sensors - each providing a combination of characteristics. SmartEngine's standard model numbers and associated sensors are shown below along with the suggested standard gratings:-

By combining the choice of grating, slit and sensor it is possible to derive an optimum configuration for your application - OtO also have recommendations for specific applications.

 

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.
