Frequently Asked Questions

A concave diffraction grating is a diffractive optics component used in compact spectrometers that combines dispersive and imaging properties in a single element.

Concave gratings reduce stray light, increase light intensity, and are ideal for imaging the spectrum on a diode array or a CCD/CMOS sensor.

Concave gratings are suitable for spectrographs and spectrometers, spectroscopy, and scientific and industrial applications.

The groove density of the concave grating is 2400 ± 4 l/mm.

The storage and transport temperature range for the concave grating is -40 °C … +70 °C (non-condensing environment).
