Dlc Ar 3-12um Coated Germanium Window
The Dlc Ar 3-12um Coated Germanium Window is an infrared-transmitting optical component fabricated from high-purity germanium, with a diamond-like carbon and anti-reflection coating optimized for the 3 to 12 micrometer wavelength band. It is manufactured to a surface quality of 10-5 scratch-dig, with surface flatness of λ/2 at 632.8 nm, and parallelism of 10 arcseconds. The coating is designed for durability in high-humidity and thermal cycling environments.
Germanium is the standard substrate for thermal imaging applications due to its high refractive index and transmission in the mid-wave to long-wave IR spectrum. The DLC coating enhances scratch resistance and environmental stability, while the AR layer reduces reflectance to less than 1.5% per surface. Typical thickness ranges from 1.0 mm to 10.0 mm, with diameters customizable from 5 mm to 250 mm. The material is free of inclusions and bubbles, with a transmission efficiency exceeding 90% across the 3 - 12 μm band.
This component is primarily used in military thermal sights, industrial gas analyzers, and infrared spectroscopy systems. Buyers include defense contractors, laser equipment manufacturers, and research laboratories requiring precise thermal detection. Packaging is in nitrogen-purged, anti-static containers with foam inserts. Trade terms include FOB Changchun, with lead times of 4 to 6 weeks. Export documentation includes material certification and coating performance data.

Sourcing Dlc Ar 3-12um Coated Germanium Window from Changchun Positive Optics Co., Ltd. - China Import Guide
Before ordering, verify the germanium purity and coating specification with a material certificate and spectral transmission data. Request a surface inspection report showing scratch-dig count under 10x magnification. Confirm that the window is free of internal stress using a polariscope. Do not accept generic compliance statements without raw data from the manufacturer.
Confirm lead time with the supplier, as optical polishing and coating processes are batch-dependent. Standard terms are FOB Changchun, with payment via 50% advance and 50% against inspection report. Incoterms must be specified in writing. Packaging must include sealed desiccant bags and shock-absorbing foam. Export documentation must include a material origin declaration and coating process traceability log.
Arrange a pre-shipment inspection focused on transmission uniformity, coating adhesion, and surface defects. Use a Fourier-transform infrared spectrometer to validate the 3 - 12 μm transmission curve. Test 10% of units for thermal shock resistance. Retain one sample for future performance comparison. Ensure each unit is labeled with a batch ID matching the test reports.
