SID4 DWIR: High resolution dual band wavefront sensor

PHASICS introduces the first off-the-shelf high resolution wave front sensor for dual band infrared (from 3 µm to 5 µm and from 8 µm to 14 µm): the SID4 DWIR.

For optical metrology, the SID4 DWIR is the perfect tool to characterize IR objectives (thermal imaging and safety vision) or IR lenses (for CO2 laser) giving you MTF, PSF, as well as aberrations, surface quality and focal length.

 For laser beam metrology (CO2 laser, infrared OPO laser sources…), the SID4 DWIR gives an exhaustive beam characterization (aberrations, M², intensity profiles, beam parameters ...).

The ease of use and compactness make the SID4 DWIR very simple to integrate
