Interferometric Measurements
Our interferometric laboratories are equipped with 4" and 6" interferometers, which allow us to measure following parameters:
- Shape of polished surfaces, spherical as well as plane
- Transmitted or reflected beam wavefront deformation
- Angle deviation or wedge on plan-parallel glass
- Angle deviation of corner prisms and rectangular prisms
- Glass homogeneity
Measurement accuracy:
- Surface figure and wavefront deformation < λ/20
- Angle measurement < 1"
Our measuring results are in accordance with ISO 10110-5 requirements.
