Diffraction Gratings

Diffraction gratings come in three grades and are used to separate white light into its component wavelengths and are all available to custom solutions. Our high quality custom research reflection gratings include both ruled and holographic types, with lines at orders of 1µm or to any line width required. Our range of custom diffraction gratings can be applied to glass,IR crystal, UV materials such as calcium fluoride and UV grade fused silica.

Knight Optical’s custom diffraction gratings are primarily used in monochromators and spectrometers, as well as other applications where wavelengths of light require isolating.

Our custom holographic gratings have lower stray light levels and are available in closer proximity rulings, however ruled are generally more efficient. Blazed holographics are also available with a similar profile and efficiency to ruled types for use at UV wavelengths.

We also offer custom transmission gratings which are useful for simple demonstration applications. Our commercial range of gratings consists of inexpensive transmission replicas mounted between glass plates.

Knight Optical supply high quality custom diffraction gratings made to your exact custom specification. Every component is individually tested by our highly skilled technicians in our state of art metrology to ensure all components meet our high quality standards.
