Diffraction Gratings are optical components used to separate light into its component wavelengths. Diffraction Gratings are used in spectroscopy, or for integration into spectrophotometers or monochromators. Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating’s surface. Diffraction Gratings can be either transmissive or reflective. As light transmits through or reflects off a Grating, the grooves cause the light to diffract, dispersing the light into its component wavelengths. Diffraction Gratings should be handled with care due to soft coatings and should not be cleaned without consultation.
Production process
Ruled gratingsEbetter Optics offers a wide range of transmission or reflection Gratings for the Ultraviolet (UV), Visible, or Infrared (IR) regions. When manufactured, a master Grating is used to create replicas of itself. The manufacturing process determines the type of Grating. A Ruled Grating consists of a series of grooves that have been ruled into the surface of a master grating utilizing a fine diamond tool. Ruled Gratings are used in applications that require high efficiency. Holographic Gratings are manufactured using the interference fringe field of two laser beams. Holographic Gratings are ideal for applications that require minimal stray light.
