Multi-wavelength Laser Planar Interferometer

Based on the principle of Fizeau interference and mechanical phase shifting and equipped with the self-developed super-achromatic beam expanding and imaging system, the interferometer supports the plug and play of laser source with the working wavelength in the range of 600 - 1600 nm.

Product Description

Based on the principle of Fizeau interference and mechanical phase shifting and equipped with the self-developed super-achromatic beam expanding and imaging system, the interferometer supports the plug and play of laser source with the working wavelength in the range of 600 - 1600 nm.

Main advantages: 

1.When changing laser source with another wavelength, no adjustment is needed.
2.The interferometer can be equipped with self-developed absolute test accessories to obtain the absolute surface error of a surface with an accuracy better than λ/40.
