Product description
We can provide right-angle prisms within the range of 3-100mm. Conventional materials include N-BK7, UV fused silica, CaF₂, SF materials, etc. And anti-reflection coatings or reflective coatings can be applied according to customer requirements.
Material Selection: BK7 material is suitable for the visible to near-infrared band, with a relatively low price and stable performance.
Fused silica material is suitable for the deep ultraviolet to near-infrared band, with a low coefficient of thermal expansion, and can be used in ultraviolet or high-power application scenarios.
CaF₂ material is suitable for the deep ultraviolet to mid-infrared band, and has good transmittance in the range of 0.13μm~10μm.
Fused silica material is suitable for the deep ultraviolet to near-infrared band, with a low coefficient of thermal expansion, and can be used in ultraviolet or high-power application scenarios.
CaF₂ material is suitable for the deep ultraviolet to mid-infrared band, and has good transmittance in the range of 0.13μm~10μm.
The right-angle prism can be used as a 90° reflector or a 180° reflector, as shown in the following optical path diagram:
