Prism
1). Right angle prism
Right angle prism is deviating or deflecting a beam of light with 90° or 180°.It is often used in telescope, periscope and other optical system. We also can supply laser grade right angle prism.
High precision right angle prism
Material: Schott glass BK7
Size tolerance ： +0.0/ -0.2mm
Surface accuracy ： λ/4@632.8nm
angle tolerance ： +/ -30”
C.A. ： 90%
2). Penta prism
You can use the penta prism to deviate images by 90 degree without inverting or reversing. There is a 90degree constant deviation for all the rays transmitted by the useful aperture. It is commonly used in Plumb Level, Surveying, Alignment, Rangefinding and Optical Tooling.
Material: Schott glass BK7
Deviation angler: 90°±3"
size tolerance ： ± 0.15mm
Surface accuracy ： λ/4( reflective surface), λ/2 (transmission surface)
S.D. ： 40/20
C.A. ： 90%
3). Beamsplitter penta prism
By adding a wedge with partial refractive coating, it can be used as a beamsplitter. We often can find it used in Plumb Level, Surveying, Alignment, Rangefinding and Optical Tooling. 4). Roof prism
It can invert and reverse an image, also, deflect the image 90° . Therefore, it is often used in terrestrial telescopes, viewing systems and rangefinders.
Specification:
Material: Schott glass BK7
Size tolerance: ± 0.15mm
Roof Angle tolerance: ±5″ (limits: ±3″)
wave distortion ： λ/4 （ 632nm ）
S.D. ： 60/ 40
C.A. ： 90 ％
5). Dove prism
The main application is used as rotator ; another application is used as a retroreflector.
6).Corner cube prism
It is often used to the distance measurement, optical signal process and laser interferometer.
Material: Schott glass BK7
Size tolerance: +/ -0.15mm
Surface accuracy: λ/4@632.8nm
S.D. : 60/ 40
C.A. : >85%
7).Wedge prism
It is used as beamsteering elements in optical system. |
