Optics: Other optical components & peripheral parts

A diffraction grating is an optical element used to separate light into its constituent wavelengths. Diffraction gratings are used in spectroscopic analysis and are integrated into spectrophotometers and monochromators. The surface of a diffraction grating is treated with a series of closely spaced grooves formed by scribing or etching. Diffraction gratings function either by transmission or reflection. Optical fibers, or fiber optics, are widely used for data transmission and light guide applications. Optical fibers used in light guide applications are ideal for medical, inspection, automotive, and display applications because they guide safe light that does not generate heat. Lens cleaning supplies are used to clean and safely handle delicate optical elements for maintenance and inspection applications.
