Product description:Optical attenuator is an optical component that can change the output power of laser continuously. It is consisted of a half-wave plate (or an electro-optic crystal) and a polarizer. The polarization state of incident light is modulated by the half-wave plate (or electro-optic crystal) therefore to vary the degree of attenuation. The polarizer can divide the light further into two beams at a specific ratio. Optical attenuators are ideal for the applications in precision laser processing, laser detection, laser sensing etc., especially in ultra-fast and ultra-short pulse laser systems.CASTECH provides two types of attenuators according to different modulating principles:mechanica
l and electro-optical type.Mechanical attenuator modifies the polarization state of light by rotating the half-wave plate. It is characterized by compact structure and adaptability.Electro
-optical attenuator can be used as a high-speed optical switch which can accomplish a modulation in nanoseconds. CASTECH's optical attenuator has two control schemes, electric and manual. Attenuator can be equipped with PBS, Brewster window, or removable optical trap as optional accessaries.Applicat
