Optical & Laser Instruments

Our product range contains a wide range of Optical Flat, Equilateral Prism, Penta Prism, Dove Prism and Right Angle Prism

Optical Flat

Optical Flat
  • Material Zerodur, Fused Silica, Pyrex, BK7
  • Surface accuracy: l/2, l/4, l/8
  • Parallelism 3 arc min
Optical Flat is a precisely polished flat surface, used as a reference, against which flatness of an unknown surface may be compared. When an optical flat is placed on a polished flat surface, with a monochromatic light incident on it, dark and light fringe pattern, called interference pattern is visible. The shape of the fringes gives the visual representation of the flatness of the surface under test.

Equilateral Prism

Equilateral Prism
  • Dimensional Tolerance: + 0.1mm
  • Surface Quality: 60-40
  • Size range: 3mm - 50mm
Equilateral Prism It is used as dispersing element in instruments and experiments, which requires wavelength separation. It has three equal 60o angles.

Penta Prism

Penta Prism
  • Dimensional Tolerance: + 0.1mm
  • Surface Quality: 60-40
  • Angle Tolerance + 15 arc sec.
Penta Prism is neither inverted nor reversed as it is deviated by 90o, It is a constant deviation prism, i.e. slight movement of the prism does not affect the true right angle at which light rays are reflected. It shortens the optical path length of an instrument.

Dove Prism

Dove Prism
These prisms are used as image rotators.When the prism is rotated, the image passing through will rotate at twice the angular rate of the prism. The hypotenuse face of a dove prism is the face of the largest area. This prism is used in the total internal reflection(TIR) mode, with unaluminized hypotenuse face.

Right Angle Prism

Right Angle Prism
  • Material BK7 or Fused Silica
  • Size From 2mm to 50mm
  • Dimensional Tolerance : + 0.1mm
Right Angle Prism It is usually preferred over an inclined mirror as it is easy to mount and can handle external mechanical stresses.Very high transmission can be achieved by using the hypotenuse face in Total Internal Reflection mode and with entrance and exit surface anti reflection coated.If the hypotenuse faces may not be kept clean due to environmental conditions it is advisable to aluminize hypotenuse surface.

Precision Right Angle Prism

Precision Right Angle Prism
  • Dimensional Tolerance: + 0.1mm
  • Surface quality: 60:40
  • Bevel 0.3mm X 45o
Precision Right Angle Prism It is usually preferred over an inclined mirror as it is easy to mount and can handle external mechanical stresses. Very high transmission can be achieved by using the hypotenuse face in Total Internal Reflection mode and with entrance and exit surface anti reflection coated. If the hypotenuse faces may not be kept clean due to environmental conditions it is advisable to aluminize hypotenuse surface.
