Custom Right Angle Prisms Bk7 / UV Fused Silica Redirect Light At 90 Degrees

Right angle prisms are used to deflect a beam of light through 90 or 180 degrees. This can be used as component to create various optical devices. BK-7 can be used for a range between the visible and infrared light. fused-silica can be used for a range between ultraviolet and infrared light. JUKA offers a wide range of different materials and different degree of precision prisms. Beam Deflection Angle: Material: 90°±3',180°±5' H-K9L/UV Fused Silica Diameter Tolerance: Surface Flatness: 0/-0.1 λ/5 Scratch/Dig 60/40 Clear Aperture: Bevel: >90% 0.2±45° Coating: Lacquer: AR OR BBAR GT-7or equivalent There are many types of prisms, each having a particular geometry to achieve the reflections necessary to perform a specific imaging task. Reflecting prisms may invert, rotate, deviate or displace a beam. dispersing prisms produce spectral separation for spectroscopic applications or for tuning a laser output. JUKA offers many kinds of high precision prisms, please keep in mind that selection of the most suitable prism is primarily dependent on the application. Material BK7 and Fused silica typically, Visible optical glass, Infrared optical glass.
