Product Strengths
1. Optimized Infrared Transmission Performance
Our CVD grade ZnSe, ZnS and Germanium substrates deliver high transmittance across target infrared bands. Custom IR AR coating cuts surface reflection loss and maximizes signal throughput for thermal imaging and laser systems.
2. High Precision Optical Surface Quality
Single point diamond turning and advanced polishing achieve excellent surface figure and low surface roughness, minimizing scattering and distortion for high-performance infrared detection systems.
3. Material Options For Different Working Environments
ZnSe offers superior LWIR & CO2 laser transmission. ZnS provides outstanding hardness and rain/particle erosion resistance for harsh airborne or outdoor environments. Germanium works well for both MWIR and LWIR night vision applications.
4. Integrated Flange Design Simplifies System Assembly
One-piece flanged infrared dome eliminates separate mounting adapters. Custom bolt circle pattern allows direct bolt-on installation, saving assembly cost and improving structural stability.
5. Complete Optical & Mechanical QC System
Every dome undergoes interferometer surface test, spectrophotometer transmission test and AOI defect inspection. FEA and hydrostatic test documents can be supplied for high-reliability aerospace and defense projects.
