Spectral Range MWIR (3 - 5 μm) LWIR (8 -14 μm)

Phasics SID4-DWIR wavefront sensor

The SID4-DWIR is the first off-the-shelf high-resolution wavefront sensor for dual-band infrared from 3 to 5 µm and 8 to 14 µm. It is well suited to characterize IR optics, blackbody sources, 3.39 µm or 10.6 µm laser beams, and systems.
