2" IR TF、3.39μm 與 10.6μm

Finally got this installed in my IR setup and the ZnSe substrate handles both 3.39 and 10.6 microns cleanly with no need for switching optics. The AR coating is holding up well, and the 150 nm PVr spec gives me confidence in the wavefront quality.

Swapping out a few optics on my test bench, this ZnSe flat worked exactly as needed for both 3.39 and 10.6 micron setups. The 150 nm PVr figure is tight enough for my interferometry work, and the bayonet mount made alignment simple.

The dual-band coating handles both 3.39 and 10.6 µm without needing to swap optics, which saves a lot of setup time in the lab. The 150 nm PVr spec held up well in my initial fringe analysis, and the bayonet mount feels solid on the interferometer.
