- Monochromatic wavelength 5896A = λ/2 (~0,3μ)

Technical specifications

- For optical flats up to Ø 300 mm
- Dimensions: 540mm x 540mm x 364mm
- Wavelength: Lambda/2
- Weight: 80 kg

Operation

The optical flat is placed onto the top of the workpiece to be tested where it is illuminated with monochromatic light. Monochromatic light has one single wavelength only. That is the reason why the flatness is very easy to evaluate.

For this model with bench and floor standing light units with stand, the mirror is situated inside the housing. Optical flat and workpiece are placed one upon the other, onto the light unit. The monochromatic light shall radiate upwards, and now the flatness can be evaluated the same way like for model U1050801.
