^ Optical Element-Righ.Angle Prism Right Angle Prism Right Angle Prism can be used to bend a beam by 90deg or 180deg, depending on which face is entrance face. Please refer to following image to see how it works. Now Union Optic can provide right angle prisms from 0.5mm to 50.8mm size. Special size can also be offered upon request. Dimension Tolerance Angle Tolerance BK7, UV grade Fused Silica Refer to below list Pyramidal Error Surface Quality Clear Aperture Standard Product Note: If you want to put mirror coatings on right angle prism, please refer to right angle prism mirror.

l j£> Union ©pm Qpt|ca| Element_Penta Prism J Penta Prism An incident beam can be deviated by 90 degree without inverting or reversing through a Penta prism. Penta prism has five sides, four of them polished. Two reflective sides are coated with metal or dielectric HR coating and these two sides can be blackened. The deviation angle of 90deg will not be changed if the penta prism is slightly adjusted, this will be convenient to install it. It is widely used in laser level, alignment and optical tooling.The reflecting surfaces of this prism must be coated with a metallic or dielectric...

Optical Element- Beamsplitter Penta Prism Beamsplitter Penta Prism Beamsplitter penta is combined with a penta prism and a wedge cemented on one reflective surface, a beamsplitter coating on the cemented interface to form a beamsplitter. Now the transmission/reflection (T/R) ratio of beamsplitter penta prism we provided include 20/80, 30/70, 40/60 and etc. Other T/R ratio is available upon request.

Optical Element- Corner Cube Reflector Corner Cube Reflector Corner Cube Retro Reflector operates on the principle of Total Internal Reflection (TIR). An incident beam will be reflected parallel to itself by the three roof surfaces. The reflection is insensitive to the incident angle, even when the incident beam enters the prism off normal axis, there will still be a strict 180deg reflection.

Optical Element—Porro Prism £ Porro Prism Porro prism is a type of reflection prism which can be used to alter the orientation of an image. Light enters the large face of the prism, then hits on the roof, by total internal reflection twice from the roof, the beam exits again through the large face. An image traveling through a Porro prism is rotated by 180deg but not inverted. Dimension Tolerance Clear Aperture Roof Angle Tolerance Wavefront Distortion Surface Quality Standard Product Sharp roof, other protective chamfered

Optical Element—Dove Prism Dove Prism Dove prism is always used to rotate image. If you rotate the prism around a longitudinal axis, the image rotates through twice the angle the prism rotates through. Sometimes, dove prism is also used for 180deg reflection. Dimension Tolerance Surface Quality Clear Aperture Angle Tolerance BK7 Grade A optical glass Protective chamfer Standard Product

Optical Element—Rhomboid Prism Rhomboid Prism 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. Material BK7 Grade A optical...

ical Element—Brewster Prism Brewster Prism Brewster prism is one kind of dispersion prism, it is normally used to separate two wavelengths following the same beam path. Brewster prism is designed specifically for intra-cavity laser application, the beam enters and exits the prism at Brewster's angle, minimizing intra-cavity losses. Dimension Tolerance Clear Aperture Angle Tolerance Surface Quality Polished Surface Two side surfaces polished, base is fine ground Standard Product

Optical Element—Equilateral Prism ^ Equilateral Prism Equilateral prism is one kind of dispersion prism. It has three equal 60deg angles and it can separate a beam of white light into its component colors. Equilateral prism is always used for wavelength separating applications and spectrum analysis. Dimension Tolerance Clear Aperture Angle Tolerance Surface Quality Polished Surface Three side surfaces polished Standard Product

Roof Prism With the roof surface, these prisms are used to invert and reverse the image. Union Optic can provide roof right angle prisms, roof penta or half penta prisms, Schmidt prisms, or other roof prism specified by customers. Roof Penta Prism Schmidt Prism Dimension Tolerance Clear Aperture Angle Tolerance Roof Angle Tolerance Surface Quality BK7, Fused Silica, other optical glass

Optical Element—Wedge Prism ^ Wedge Prism Wedge prism has plane inclined surfaces. It deflects light toward its thicker portion. It can be used individually to deflect a beam to a special angle. Two wedge prisms work together can assembly an anamorphic prism to correct the elliptical shape of laser beam. The wedge prism is ideal for laser beam steering applications. By combining two wedge prisms which can be rotate individually, we can direct the input beam to anywhere within the cone angle 0d, where 6d is 4x the specified angular deviation of one wedge. We can make deviation angle from...
