Windows & Filters Prisms Wedge Prisms T ● Steer beams in optical systems ● Can be used in pairs for continuous angular adjustment Beam deviation Wedge angle Specifications Material Contact us for other types of prisms e.g. trapezoidal, various isosceles, Dove, Amici, Penta, etc. Clear aperture Diameter tolerance Wedge tolerance Having selected an appropriate wedge, it is easy to create a precise beam deviation without affecting other beam parameters. If two wedges are used together with the sloping surfaces in close proximity, it is possible to produce a continuous variation of beam deviation by counter – rotating the wedges. Wedge prisms are made from alternative materials, such as UV grade fused silica, and different shapes and sizes or with various anti-reflection coatings.

● Extremely small loss of a p-polarized beam ● Light separated by wavelength is conveniently turned at an 90° angle with minimum deviation ● UV FS prisms provide 1.26° separation between 532 nm and 1064 nm Pellin-Broca Prisms In a Pellin-Broca prism, an ordinary dispersing prism is split in half along the bisector of the apex angle. Using a right angle prism, the two halves are joined to create a dispersing prism with an internal right angle bend obtained by total internal reflection. The entrance beam is deviated at an 90° angle to its initial direction. Surface quality Surface flatness Design...

Optical Components Corner Cubes Coatings ● Incident light deviates by 180 degrees independently of the angle of incidence These prisms have 3 mirror surfaces making angles of 90° to each other, juxtaposed to form the corner of a cube with the entrance face perpendicular to the cube diagonal. Respective of an incident direction, all beams are reflected back to the original direction. Solid corner cubes are used in high precision applications or with lasers over very long distances. These ”angle insensitive” mirrors therefore find frequent applications in situations where orientation is difficult...

Optical Components Fixed Ratio Cube Beamsplitters Coatings ● Two right angle prisms cemented together with a partially reflecting surface on the internal (protected) face All dielectric coatings of fixed ratio laser beamsplitters are opti­ mi­ ed to be insensitive to split only s- or only p-polarization or s only unpolarized light (R=(Rs+Rp)/2 and T=(Ts+Tp)/2) at designed wavelengths. The four outer faces are all anti-reflection coated.
