Optogama Right-Angle Prism代理

4Lasers standard uncoated right-angle (45°-90°-45°) design prisms are fabricated from UVFS and BK7 optical glasses and have three optically polished rectangular surfaces (refer to the drawing). These prisms are popular to use for 90° internal or external beam bending, 180° beam folding, image rotation. These applications exploit total internal reflection at glass-air boundary inside the prism, except 90° external beam bending, which requires metallic or highly reflective dielectric thin-film to be applied onto the hypotenuse face. To optimize particular internal application optical transsmision antireflective coatings have to be applied. Contact us for coating service, custom solutions and pricing.
