| Wedge Prisms | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
By selecting the appropriate wedge it is simple 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. Specifications

| Laser Dispersing Prisms | ||||||||||||||||||||||
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. Specifications

| 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 90° angle to its initial direction. Specifications

| Right Angle Prisms | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
These prisms are used to direct beams at 90 degrees by using hypotenuse face in total internal reflection (TIR). The right angle prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirror in response to external mechanical stress. As long as acceptance angle limitations for TIR from the roof faces are not exceeded, the right angle prisms can serve as a retro reflector, turning beams back to the original direction.

| Corner Cubes | ||||||||||||||||||
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 cube diagonal. All beams, despite of incident direction, are reflected back to the original direction. 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 or impossible to control and where a mirror would therefore be unsatisfactory.

| Non Polarizing Cube Beamsplitters | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
All dielectric coatings of non-polarizing laser beamsplitters are optimized to be insensitive to polarization at design wavelengths. The coatings hold both the s- and p-polarization components to the same ratio of reflection-to-transmission over a specific laser wavelength region. Specifications

| Fixed Ratio Cube Beamsplitters | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
All dielectric coatings of fixed ratio laser beamsplitters are optimized to be insensitive to split only s- or only p-polarization or only unpolarized light (R = (Rs+Rp)/2 and T = (Ts+Tp)/2) at design wavelengths. Specifications
