Ideal for LWIR Thermal Imaging

• Transmission from 2µm to 14µm covering both the MWIR (3-5µm) and LWIR (8-12µm) thermal wavebands.
• Uncoated germanium windows available in 10mm to 30mm diameters.
• AR/AR coated windows @ 3-12µm available in 12.5mm to 50mm diameters.
• AR/DLC coated windows @ 7-14µm available in 12.5mm to 100mm diameters.

Knight Optical can offer custom germanium windows manufactured to our customer's individual specifications as we know that these are often application specific. We can offer dimensions up to 300mm.

We can apply antireflective (AR) coatings to increase the transmission in the specific waveband, as well as a diamond-like carbon (DLC) coating to enhance the durability of the coated surface which is ideal for surfaces that are exposed within a system.
