Compact and portable, RGB-VIS-NIR-CL is a Visible-NIR miniature fiber spectrometer based on a crossed-asymmetric Czerny-Turner design. Equipped with a sophisticated CMOS detector, it has the advantages of high sensitivity, high resolution, high quantum efficiency and large dynamic range, and is suitable for spectral measurements in various scientific and industrial/OEM applications.

RGB-VIS-NIR-CL is preconfigured with a 25um entrance slit, and provides a high optical resolution of 1.0nm and a wavelength range of 400-1100nm. It is also possible to get different optical resolutions and spectral response ranges by selecting different gratings and slits.  For applications that requires an even higher resolution, RGB-VIS-NIR-CL can, for example, be preconfigured to offer an optical resolution of 0.5nm and a wavelength range of 750-1100nm.

RGB-VIS-NIR-CL has a USB2.0 interface for high-speed data transfer with a computer. It can also communicate with external devices via available GPIO pins.

   Frequently Asked Questions and Answers

  • Does RGB-VIS-NIR-CL fiber spectrometer automatically offer a resolution of 0.5nm over 750-1100nm?

    No. Under the default configuration, RGB-VIS-NIR-CL spectrometer has a resolution of 1.0nm over 400-1100nm. However, if you request it, we can preconfigure it to offer a resolution of 0.5nm over 750-1100nm. You will need to clearly specify this requiremen...
