BK7 Dielectric Right-Angle Prism Mirror, Hypotenuse Coated
Tuniu broadband dielectric film right angle prism mirrors enable precise beam deflection and calibration across the visible to near-infrared spectrum, available for two wavelength ranges: 400–750 nm and 750–1100 nm, with reflectivity exceeding 99%. The prism hypotenuse is coated with a wavelength-specific dielectric film, designed to reflect light incident on the hypotenuse from outside the prism at angles ranging from 0° to 45°, realizing efficient and accurate beam deflection.
Tuniu provides these dielectric film right angle prism mirrors in five standard sizes. For custom sizes, substrate materials, or coating specifications, please contact us.
