Optical Metrology Instruments Prisms India specialises in design and development of High Precision Optical Metrology Instrument. Instrument developed finds application in Machine Tool Industry, Research Establishments & Educational Institutions.




Autocollimator-ACT-01

Autocollimator-ACT-01
Autocollimator-ACT-01 is a Precise Instrument for small angular tilt measurements. Micro-Optic Visual Autocollimators resolution ranging from 3 arc secs to 0.5 arc secs for Straightness, Squareness, Flatness , Rotary table calibration in Machine Tool Industry. Wide range of Stands and accessories to suit various applications.
Autocollimator-ACT-01 with camera attachment available with software for Straightness & Flatness or machine Geometry measurements.

Alignment Telescope

Alignment Telescope
Highly precise Instrument to align machine bores, bearings and optical Instrument line of sight axis. Linear shift up to 30 m measured in both axes with precision Micrometer with 20 microns Resolution. Prisms India offers a wide range of targets to suit specific applications.

Alignment Autocollimator

Alignment Autocollimator
Prisms India offers a combination of Autocollimator and Alignment Telescope. This can measure angular shift and linear shift. Special Mirror target with cross line available.


Target Collimator

Target Collimator
Collimator for alignment application. Custom made graticules are available. 40 mm diameter x 430 mm focal length, 30 mm dia x 286.5 mm focal length and other custom made Collimators are available.


Fizeau Interferometer

Fizeau Interferometer
Non Contact Flatness measurement Interferometer for inspection of flatness of optical or mechanical parts.

For use in Optics Industry and Automobile Industry .

Grazing Interferometer

Grazing Interferometer
Non Contact Flatness measurement Interferometer for inspection of flatness of mechanical lapped non reflective parts. For use in Mechanical seal, Pump valve and Automobile Industry .


Linear Interferometer

Linear Interferometer
Laser Interferometer LSP 30-3D is the two frequency interferometer used mainly for investigation of the machine tools geometry. The small size and weight makes it easy for transportation which is very important factor in the service applications.
Measurement abilities: Linear positioning, Angular positioning, Velocity, Straightness, Flatness, Squareness &
Rotary positioning

Michelson Interferometer

Michelson Interferometer
The Michelson interferometer is the most common configuration for optical interferometry and used in Physics & Optics Lab in Educational Institutions. Supplied on a bread board table. Upgrade facility to add parts to perform as Fabry Perot & Twyman Green Interferometers.

Micrometer Anvil Checker

Micrometer Anvil Checker
Measures parallelism (non contact) between the anvil and spindle faces. Replaces the use of Optical Parallel. Can be used from 25 mm to 300 mm range Micrometers. It employs the use of an Autocollimator that could also be used for surface table calibration.

Monochromatic Light Source

Monochromatic Light Source
Light Source to check flatness of lapped parts with Optical Flats. Also useful for checking Micrometer Anvils in Calibration labs.

For use in Optics Industry and Automobile Industry .

Shear Plate Collimation Tester

Shear Plate Collimation Tester
The shear Plate interferometer is an extremely simple means to observe interference and to use this phenomenon to test the collimation of light beams, especially from laser sources which have a coherence length which is usually a lot longer than the thickness of the shear plate (see graphics) so that the basic condition for interference is fulfilled.
