Optical Components
Fused Silica Wedge Prism
PARAMETER:
The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from the prism.

The wedge prism can be used to individually deflect a laser beam by a certain angle or combined with another optical wedge prism for beam deviation purposes. A single prism can shift the incident beam by a specific angle. When two wedge prisms are used together, they can function as deformable prisms to correct the elliptical beam output of a laser tube or to deflect the beam at various angles within a 4�¸ range, where �¸ represents the deflection angle of a single prism. This beam shaping is achieved by independently rotating the two wedge prisms, making it ideal for beam scanning at different positions in imaging applications.

Features of Wedge Prism
The characteristics of wedge prisms include their very small apex angle (typically less than 1/10 radian), which results in minimal deflection of light as it passes through, regardless of the angle of incidence. In optical instruments, two wedge prisms are often combined and rotated relative to each other to produce different deflection angles or to convert the minimum deflection angle of light into the relative rotation angle of the two prisms. This setup is used to compensate for small angular deviations in the measurement of light. Such prisms find applications in many optical instruments, including military rangefinders and camera viewfinders.

Applications of Wedge Prisms
Laser Scanning: Wedge prisms can adjust the direction of the outgoing beam through rotation, making them commonly used in laser scanning devices.

Optical Pointing: In machine vision applications, wedge prisms are used to position the cameraâ??s field of view to the region of interest.

Beam Attenuation: By utilizing double Fresnel reflections, wedge prisms can attenuate high-power lasers while maintaining the beamâ??s polarization, size, and shape.

Beam Shaping and Translation: Wedge prisms can be used for beam shaping and translation, making them suitable for a variety of optical systems and applications.

Rochon Polarizers

Rochon polarizer is made of two birefringent material prisms cemented or optically contacted together. The Rochon prism was invented by and is named after Abb Alexis Marie Rochon. It is in many ways similar to the Wollaston prism, but the ordinary ray passes through the prism undeviated. Any separation angle can be designed according to request of customers.

Features

Multiple Polarization Materials Available
Ordinary Rays Pass Through Undeviated
Extraordinary Rays Deviate
