Right-angle prisms

As a meam turner (90 degrees deflection)
As a retro-reflector (180 degrees deflection)

Glass Perfection provide large amounts of right-angle prisms, they are generally used to have two functions:

90 degree deflection occurs at the hypotenuse face. Image viewed through a single right angle prism will be erect but reversed left to right.

The retro-reflection is insensitive to rotate an axis parallel to the roof.

Specifications:

Diameter Tolerence: +0.1mm
Clear Aperture: > 80%
Angle Tolerence: < 3 Min deviation
Surface Flatness: ^/4@632.8 mm
Surface Quality: 20-10 to 60-40 scratch and dig
Bevel: 0.25mm to 0.5mm

Material:

BKY grade A optical glass
High purity uv grade fused silica

Coating:

Glass Perfection provides varieties of single layer or multi layer anti reflecting coating on optical windows.

High Precision Perpendicularity Right-angle Prisms

Glass Perfection also provide BKY or fused silica right-angle prism with excellent perpendicularity of ground surface and polished surfaces. Such prisms are useful for high precision optics application, which requires a good ground reference flat.

Penta Prisms

Penta prisms are a five-sided prism containing two reflecting surfaces at 45 degrees to each other and two reflecting faces perpendicular to the entering and emerging beam.

Penta prisms have two important properties:

  • the image is neither inverted nor reversed while deviated by 90 degrees
  • it is a constant deflection device, all transmitted rays are deviated by the smae exact 90 degree.

Specifications:

Material: BKY Grade A Optical Glass
Dimension Tolerance: +- 0.2mm
90 Degree Deviation Tolerence: <30 arc seconds
Precision Series: <10 arc seconds
Flatness Standard Series: ^/2@ 632.8nm
Reflectivity: R>95% per face from 630 to 680nm
Surface Quality: 60-40 scratch and dig

Beamsplitters Penta Prisms

By adding a wedge and with partial reflective coating on surfaces S1, penta prisms can be used as beamsplitter, transmission/reflection ratio of 20/80, 50/50 or others for beamsplitter penta prism is available upon request. (this doesn't seem to make sense).


Specifications:

Material: BKY Grade A Optical Glass
Dimension Tolerance: +- 0.2mm
90 Degree Deviation Tolerence: standard series <30 arc seconds
Precision Series: <10 arc seconds
Flatness Standard Series: ^/2@ 632.8nm
