BK7 wedge prism is an optical component made of BK7 optical glass, featuring a wedge-shaped structure (two flat surfaces tilted at a slight angle). It is primarily used for beam deflection, collimation, or optical system alignment in the visible to near-infrared (NIR) wavelength.
When is a BK7 (K9) wedge prism the more suitable choice?
The working band is visible(400-700 nm) or near-infrared (700-2000 nm). The budget is limited and no ultraviolet or ultra-high thermal stability is required. It is used for low-power laser or ordinary optical adjustment (such as laboratory optical path calibration).
Wedge Prisms (Risley prisms) has two plane faces slightly inclined to each other, the wedge apex angle.
