Keil Prisma YT-359

aus BK7-Glasmaßgefertigt

Place of Origin: Jilin, China Brand Name: YT Model Number: YT-359 Material: N-BK7 Dia: 12.5mm Edge Thickness: 1.5mm Wedge Angle: 0° 58' Surface quality: 60/40 Bevel: Protective bevel as needed Angle Tolerance: ±30arcsec Design Wavelength: 632.8nm Coating: Uncoated Wedge Prism Wedge prisms can be used individually to deviate a laser beam a set angle, or two wedge prisms can be used together for beam steering applications A single wedge prism's ability to deviate the angle of an incident beam is measured in Diopters with 1 diopter deviating the beam 1cm at a 1m working distance. Two wedge prisms can be used as an anamorphic pair for beam shaping (to correct the elliptical shape of diode outputs). Or, a pair of wedge prisms can steer a beam anywhere within a circle described by the full angle 40, where θ is the deviation from a single prism. This beam steering is accomplished byrotating the two wedge prisms independently of each other, and is typically used to scan a beam to different locations in imaging applications.
