法国SILION公司 衍射光学元件
衍射光学元件(Diffractive Optical Elements) 简称 DOE, 又称二元光学器件,主要用于激光束整形,比如均匀化、准直、聚焦、形成特定图案等。法国SIIOS公司提供客户定制的衍射光学元件DOE,适用于对Nd:YAG、CO2、飞秒激光器、半导体激光器等各种激光器进行光束整形。根据不同的应用需求,衍射光学元件DOE可以作为全息片或菲涅耳波带片。其主要产品包括:- Beam splitter (or fan-out): used to split a single input laser beam in several output laser beams according to a defined diffraction pattern (spot array, dot matrix). - Beam shaper: used to shape a gaussian laser beam in a Top Hat, circular or cylindrical profile according to given intensity and plane. - Pattern generator (or diffuser): used to generate patterns such as logo, squares, lines, circles according application needs. - Diffractive lenses: used to correct chromatic aberrations |
