Optical Prisms
Optical Prisms product line includes: standard wedge prisms (40-20 scratch & dig, surface flatness: λ/4@633 nm); precision wedge prisms (20-10 scratch & dig, surface flatness: λ/4@633 nm); laser dispersing prisms (made of BK7, UV FS or SF11 optical material); BK7 or UV FS Pellin-Broca Prisms; right angle prisms; corner cubes; non-polarizing cube beamsplitters (coated for 532 nm, 633 nm, 1064 nm wavelength); fixed ratio cube beamsplitters (coated for 266 nm, 355 nm, 488-515 nm, 532 nm, 633 nm, 800 nm, 1064 nm, 1550 nm).
By selecting the appropriate wedge it is simple to create a precise beam deviation without affecting other beam parameters.

Like Brewster Angle Windows, Laser Dispersing Prisms can be used inside the cavity of laser operating on very low gain laser transitions, where even slight reflection losses may be intolerable.
In a Pellin-Broca prism, an ordinary dispersing prism is split in half along the bisector of the apex angle.
Right Angle Prisms are used to direct beams at 90 degrees by using hypotenuse face in total internal reflection (TIR).
Corner Cube has 3 mirror surfaces making angles of 90° to each other, juxtaposed to form the corner of a cube with the entrance face perpendicular to cube diagonal.
All dielectric coatings of non-polarizing laser beamsplitters are optimized to be insensitive to polarization at designed wavelengths.
