Richardson Gratings™ High Precision Reflective Holographic Diffraction Gratings display reduced light scattering compared with ruled gratings, making them ideal for stray light sensitive applications such as Raman spectroscopy. The gratings are recorded in a photoresist by exposure to an intense laser interference pattern and then chemically developed to reveal a fringe pattern with a sinusoidal cross section. Gratings for use from the UV to NIR spectral regions are available.

Note: The surface of these gratings is very sensitive and should never be touched when handling the optic. If cleaning is required to remove dust particles, non-contact cleaning using clean compressed air is recommended.

What is the difference between reflective and transmission gratings?

What is the blaze angle and blaze wavelength of a grating and how are they related?

How do I handle and clean my gratings?

I would like to select a narrow band of light with a grating, lens and pinhole setup. Since the grating’s resolving power is decided by the number of grooves illuminated by light, can it resolve anymore?
