UV right-angle prism

• Material: UV fused silica
• Working wavelength: 185nm-2.1μm
• Use: Deflect the optical path by 90° or 180°

       The Right Angle Prism is a refractive prism used for optical path adjustment, typically used to achieve 90° and 180° steering of the beam. Due to the principle of total internal reflection (TIR), when light enters from one right angle surface of a right angle prism, the light will be fully reflected at the glass/air interface of the inclined plane and exit from another right angle surface, which deflects the incident light by 90°. Therefore, it is suitable as a suitable alternative to mirrors. When the input light is incident from the inclined plane of the prism, the light will be fully reflected at the glass/air interface of the right angle plane, followed by a second total internal reflection as it passes through the next right plane, and finally exit from the inclined plane in the direction parallel to the incident beam, so that the incident light is deflected by 180°. As with the backward mirror, the 180° deflection generated by this optical path is independent of the angle of incidence.

UV right-angle prisms are based on UV fused silica, which is ideal for applications in the UV to near-infrared bands because UV fused silica provides high transmittance in the deep UV region and has a very low fluorescence level compared to natural quartz, producing almost no laser-induced fluorescence. In addition, compared with K9 glass, it has a wider spectral range (185-2100nm), better homogeneity, and a lower coefficient of thermal expansion.

Dimension-labs offers a wide range of UV right-angle prisms (specific sizes and parameters can be filtered from the details below) to meet the needs of a variety of applications.
