Monochromator Grating 522 00 140
Description
Using Type IV aberration-corrected monochromator Gratings, a single concave grating disperses, collimates and refocuses the light from the entrance slit onto the exit slit. Wavelength scanning is obtained through a simple rotation of the grating. The groove spacing of these gratings is computeroptimized to produce high quality images with a minimum
of astigmatism and coma, even at large numerical aperture. Compared with Czerny-Turner monochromators (equipped with one plane grating, one collimating mirror and one focusing mirror) Type IV aberration corrected monochromator gratings provide much better light collection efficiency and signal-to-noise ratio.

Features
In addition to the standard lists of Type IV flat field and monochromator gratings, HJY currently produces specific aberration-corrected concave gratings to maximize performance for a given application. In that case, using proprietary ray-tracing software, we optimize performance: resolution, throughput and signal to noise ratio. We need following data from our customers:
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: in general deviation has to be
minimum to improve correction of astigmatism, so indicate possible minimum deviation when overall dimensions of source, sample chamber and detector are taken into consideration.
at exit: if monochromator, exit slit width and height, and if flat field, length of detector, height and width of pixel.

Frequently Asked Questions
Customers need to provide 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, and minimum deviation.
It is a type of grating used in monochromators that disperses, collimates, and refocuses light from the entrance slit onto the exit slit. It provides better light collection efficiency and signal-to-noise ratio compared to Czerny-Turner monochromators.

A Type IV flat field grating is used for imaging applications, while a Type IV monochromator grating is used for spectral analysis. The groove spacing of the gratings is optimized differently to produce the desired results.
Wavelength scanning is the process of changing the wavelength of the light passing through the monochromator. It is achieved through a simple rotation of the grating.
