Literature & Downloads

These flat Ruled and Holographic Gratings are fabricated from BK 7 glass substrates, coated with an AlMgF₂ broadband reflective coating. Fig. 1 shows efficiency curves for two of our most popular UV gratings. Fig. 2 shows the reflectance of an IR grating.

Mounting in an Oriel Monochromator/Spectrograph

We offer many of these gratings mounted in pre-aligned holders for use in Oriel Monochromators and Spectrographs; they are listed on the individual instrument pages. (Note, in some cases the full primary wavelength range is limited on the long wavelength side by the instrument’s mechanical stop.)

Cleaning and Handling

Do not touch the surface of the grating; handle the grating by the edges and always wear gloves or finger cots. Use a non-contact cleaning method such as dry, compressed air or a dust bulb to remove excess dust from a grating.
