  • SW series is specially designed for long wavelengths range.,Maximum spectral b range :900~1700nm
  • High SNR、higher sensitivity.、High Resolution、High cost effective
  • The best choice for food, pharmaceutical and biochemical testing applications

SW (SidewinderTM ) Series spectrometer ,built with the InGaAs type sensor and high performance 32bits RISC controller in, is specially designed for long wavelengths range. The optical engine is very simple and optimized for the spectrometer. The optical bench is very rigid and stable for measurement system, especially SW series has outstanding stability of thermo-hygro variation, vibration and shock on resolution and wavelength shift performance. The compact size is very flexible for system integration.

SW Series spectrometer is constructed by the Czerny-Turner optical design and can provide the high optical resolution, high sensitivity, low stray light, and fast spectral response.

The electronics system is powered by USB port and SW Series communicates with the PC through the USB port. It also provides 6 I/Os for external interface extension.

The optical detector used in SW Series spectrometer is a highsensitivity InGaAs linear sensor. We provide the related information and the detailed instructions of how to operate with SW Series in this guide.

SW Series electronics operation is controlled by the RISC controller. So users can communicate to the main program through the PC software and the protocol provided by OtO Photonics.
