Product Name Notes
Diffraction gratings separate white light into its component wavelengths. Our commercial ranges are available in four grades of 100, 200, 300 and 600 lines per mm. All four types are...
Knight Optical's bar gratings are manufactured by photolithographically layering a chromium pattern of bars over a glass substrate. The printed lines are equally spaced and used to provide sharp contrast...
Knight Optical's high quality holographic research range of diffraction gratings are used to separate white light into its component wavelengths. This type of grating has lower stray-light levels than ruled...
Ruled diffraction gratings separate polychromatic light (white light) into its component wavelengths and are well suited for high precision applications, having a higher efficiency than other types of grating, Straight...
