SW LogoOtO Photonics' SideWinder Series of Czerny-Turner cavity spectrometers are specifically designed for operation in the near infrared region.

 

SideWinder spectrometers operating over a range of 900-1700nm are offered with a choice of 128-pixel (SW2520), 256-pixel (SW2530) and 512-pixel (SW2540) linear InGaAs sensors along with a one-stage TE-cooled 256-pixel (SW2830) version.

 

For a wider spectral range of 900-2500nm OtO's SW2960 features a two-stage cooled 256-pixel extended responsivity array.

Each SideWinder model is offered with a standard grating(s) but can be specified with a choice of Slit width to optimise the Resolution/Sensitivity compromise, these are shown below. When selecting the Slit size bear in mind that a narrower slit lets in fewer photons and so has lower Sensitivity.
