Frequently Asked Questions

We need spectral range, configuration of use (monochromator or spectrograph), numeral aperture (F number) or size of grating, maximum overall dimension or maximum focal length, desired dispersion, desired resolution, entrance slit width and height or source geometry, minimum deviation, and at exit (if monochromator, exit slit width and height, and if flat field, length of detector, height and width of pixel).

Type IV aberration-corrected monochromator gratings provide much better light collection efficiency and signal-to-noise ratio compared to Czerny-Turner monochromators equipped with one plane grating, one collimating mirror, and one focusing mirror.

The purpose of using proprietary ray-tracing software is to optimize performance, including resolution, throughput, and signal-to-noise ratio, for a given application when producing specific aberration-corrected concave gratings.

It is a type of grating that disperses, collimates, and refocuses light from the entrance slit onto the exit slit, with wavelength scanning achieved through a simple rotation of the grating.
