Grazing Interferometer
Laser Interferometer
Features:
- Small size (60x60x300 mm)
- Application of notebook
- Easy operation
- Low price
- High resolution
- High accuracy
- Small size measurement optics
Measurement abilities:
- Linear positioning
- Angular positioning
- Rotary positioning
- Straightness
- Flatness
- Squareness
- Velocity
Very good technical parameters allows to use interferometer in scientific laboratory for the precisely positioning and length standard calibration.
An Autocollimator is for measurement of angular tilts whereas the Alignment Telescope is for establishing an accurate line of sight.
Alignment Autocollimator is a combination of Alignment Telescope and Autocollimator.
Autocollimator Mode
Where a collimated light beam is projected out of the Instrument and received back after the reflection from a mirror target.
Telescope Mode
Telescope mode where the lens position is altered to focus a cross line target located at different distances.
The advantage of this Instrument is to measure the angular tilts and the shift of centre location in one setting.
Application:
- Bore straightness
- Alignment of rolls in paper, metal, and plastic mills
- Bearing run out
- Checking parallelism of bearings in a gear box
- Shaft alignments
- Gear box evaluations

Collimation Tester
Shear plates are ideally suited to determine the proper adjustment for a laser collimation system. They can also be used to measure wavefront radius of curvature, determine wavefront symmetry, measure the power of long-focal-length optics and in some cases analyze wavefront aberrations.
