Category
Diffractive Optics
Origin
China

Diffractive Optical Elements (DOE) are emerging optical elements that have flourished in recent years. DOEs usually use micro-nano etching processes to form two-dimensionally distributed diffractive units; each diffractive unit can have a specific profile and refractive index, finely regulating the phase distribution of the laser wavefront. After passing through each diffractive unit, the laser diffracts and interferes at a certain distance (usually at infinity or the lens focal plane), forming a specific light intensity distribution. ELITE cooperates with many high-quality overseas DOE suppliers, and can also customize DOE lenses according to customer requirements, selecting high-quality DOE lenses. There are 16 different patterns available, including dot matrix, 3-line, 5-line, 7-line, 11-line, 81-line, etc.
