Strahlteilerplatte für Laser-Linien 30mm Durchmesser 157nm

PSMH-30C03-P-157

Laser line plate mirrors are plate beamsplitters that are optically coated with dielectric multi-layer on the front surface of optical parallels or wedged substrates. The rear surface is coated with multi-layer anti-reflection.

Details

◦Half mirrors divide input beam into reflectance and transmittance ratio of 1:1. A beamsplitter of R:T=1:1 is called “Half Mirror”.
◦Any loss from the input beams of this product is minimized because dielectric coatings have no absorption properties. However, the input ratio of reflection to transmission depends on wavelength, polarization and angle of incident of input beam.
◦Plate beamsplitters have beam deviations on transmission and ghost on rear surface reflections. Wedged substrates are used to prevent ghosting.

Leitfaden	Für kundenspezifische Produkte wenden Sie sich bitte an unseren Vertrieb. (Customized on size, wavelength or R:T, etc.) WEB-Referenzkatalogcode/W3802 We also have ultra-wideband, broadband and cube types. For a guarantee in reflected wavefront error or transmitted wavefront error, please contact our Sales Division with your requests. Wedged types are marked with an arrow on the side of the substrate indicating the thickest point of the wedge.
Achtung	Should these products not function as a half mirror, please check the polarization characteristics of the light source. Do note that LD laser is linear in polarization. The beam deviation at transmission of a wedged beamsplitter is large compared to a one made of optical parallel. The amount of beam deviation of a beamsplitter depends on the thickness of the substrate and the wavelength or the incident angle of the input beam. Transmission curves are based on actual measurements and may vary with manufacturing lots. Surface flatness is the reflected wavefront distortion of the surface prior to coating. Tragen Sie unbedingt eine Laserschutzbrille, wenn Sie den Strahlengang überprüfen und die optische Achse einstellen.
