Frequently Asked Questions

The benefits of the PGS family of spectrometers include being compact without movable parts, permanently aligned, robust even in harsh environments, fast and simultaneous read-out, permanently calibrated, high dynamic range, high light sensitivity, high reproducibility, and low temperature drift.

The maximum efficiency of the gratings for the PGS family is adapted to the special wavelength range in the NIR.

The input fiber is used for the coupling of light and is performed in the standard way via a glass monofiber.

The PGS NIR 2.2-256 Spectrometer is designed for use in the NIR (near-infrared) wavelength range.

InGaAs (indium-gallium-arsenide) is used as a detector material in this wavelength range.
