Right angle prismright angle prism may be used as a 90 degree reflector or 180 degree retroreflector. The prism deflect, deviate and rotate beams of light as well as dispersing their wavelengths. They usually used for beam deviation or as substrates for beam splitters. We also provide other optical prism such as roof prism.Capacity:material: optical glass, fused silica, sapphire.Dimension: 1-250 mmdimension tolerance: +0-0.1 mmsurface flatness: 10@632.8 nmsurface quality: 10-5angular accuracy: 5 secondcoating: uncoated, ar, hr, beamsplitter ect.

Penta PrismFor penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled. We can supply high dimension and angle control penta prism. The coating or painting is designed by customer according to it is detailed application.Capacity:Material: Optical glass, Fused silica, Sapphire.Dimension: 1-250 mmDimension Tolerance: +0-0.1 mmSurface Flatness: 10@632.8 nmSurface Quality: 10-5Angular Accuracy: 5 SecondCoating: Uncoated, AR, HR, Beamsplitter ect.Specification:Material BK7 grade A optical glassDimension (h) Tolerance 0.1 mmDimension (A) Tolerance 0.2 mmClear Aperture >80%Surface Quality 60-40 scratch and dig90 Deviation Tolerance: < 30 arc sec., up to 5 arc sec.Flatness: 2 at 632.8 nm(Standard), up to 4 @632.8 nmReflectivity R>95% per face @630-680 nmProtective Bevel 0.25 mm x 45 BK7 Penta Prism Standard Products:A x h (mm) 1 min. deviation 30 sec. deviation 10 sec. deviation 5sec. deviationPart No. Part No. Part No. Part No.7 x 6 TPP101 TPP201 TPP301 TPP4018 x 8 TPP102 TPP202 TPP302 TPP40210 x 10 TPP103 TPP203 TPP303 TPP403Note: Other sizes, material and coatings are available upon request.

Dove PrismDove Prism is a form of prism invented by H. W. Dove. It resembles half of a common right-angle prism in which a ray entering parallel to hypotenuse face is reflected internally at that face and emerges parallel to its incident direction. One of the incident rays emerges along a continuation of its incident direction, and if the prism is rotated about that ray through some angle, the image rotates through twice that angle. A Dove Prism must be used in parallel light.Capacity:Material: Optical glass, Fused silica, Sapphire, ZnSeDimension: 1-250 mmDimension Tolerance: +0-0.1 mmSurface Flatness: 10@632.8 nmSurface Quality: 10-5Angular Accuracy: 5 SecondCoating: Uncoated, AR, HR, Beamsplitter ect.Specification:Material BK7 grade A optical glassDimension Tolerance +0.0-0.2mmClear Aperture >85%Surface Quality 60-40 scratch and digAngle Tolerance < 3 arc minutesFlatness: 2@632.8nmProtective Bevel 0.25 mm x 45 Dove Prism Standard Products:Part No. Material Model A (mm) B (mm) h (mm)TDP101 SF11 180 9.3 2.6 1.3TDP102 SF11 180 14.0 5.0 2.6TDP103 BK7 Dove 21.1 5.0 5.0TDP104 BK7 Dove 42.3 10.0 10.0TDP105 BK7 Dove 63.4 15.0 15.0TDP106 BK7 180 80.0 20.0 20.0Note: Other sizes, material and coatings are available upon request.
