Beamsplitter Cube

Wedge prisms, commonly crafted from high - quality optical materials such as BK7 glass, share analogous functions with optical windows and can act as isolating components within optical systems. They are engineered to induce a slight, exact angular deviation to light beams, efficiently blocking light from reverting to its origin. This characteristic renders them immensely useful in applications like laser alignment systems, optical measurement instruments, and imaging arrangements. With precise control over the deviation angle—typically featuring strict tolerances—they guarantee dependable performance across diverse optical setups. Whether in research laboratories or industrial optical applications, wedge prisms play a pivotal role in optimizing light paths and elevating the accuracy of optical systems.

Dove Prism has two applications. The main application is used as a rotator. It can rotate an image but without deviating the beam. And when the prism is rotated about the input parallel ray through some angle, the image rotates through twice that angle. It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean. Another application is used as a retroreflector. For this application it perform as a right-angle prism.

Penta Prism can deviate an incident beam without inverting or reversing to 90°. The deviation angle of 90° is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Rangefinding and Optical Tooling.

Rhomboid Prism can displace a laser beam without change the image orientation, the input beam is totally internal reflected by two 45degree faces and goes out from the output face. Then, a lateral displacement is produced. Higher transmission rate can be achieved by anti-reflective coating on the input and output faces. Rhomboid prism is always used in stereoscopic system and periscope system.Currently we can make angle tolerance <5 arc seconds, total beam deviation <30 arc seconds. Large size is also available.
