Choosing the appropriate infrared optical material depends on operating wavelength, transmission characteristics, environmental conditions, mechanical strength and coating requirements.
ZnSe is widely applied for CO2 laser systems and mid-infrared optical equipment due to its low optical loss at laser wavelengths. Germanium (Ge) Infrared Material provides stable high transmittance in the 8-14μm long-wave infrared band, making it suitable for thermal imaging cameras.
Multispectral ZnS delivers visible to LWIR multispectral transmission, balancing multi-band performance for surveillance and outdoor optical systems. Silicon and infrared quartz are commonly used for near-infrared and medium-infrared industrial monitoring devices.
Please provide material requirement, dimensions, tolerance, infrared spectral band, coating specification and application environment for engineering evaluation.
They are used for thermal imaging, laser processing, gas analysis, infrared spectroscopy, surveillance, industrial monitoring and scientific optical systems.
Common industrial ranges include near IR, MWIR 3-5μm and LWIR 8-14μm, selected according to the sensor, source and application environment.
ZnSe is often selected for CO2 laser and mid-IR optics, ZnS supports multispectral transmission, and Germanium is widely used for LWIR thermal imaging.
CVD ZnSe is commonly selected for CO2 laser optics because it supports the laser wavelength and can be processed with appropriate AR coating.
Germanium (Ge) Infrared Material is frequently used for 8-14μm LWIR thermal imaging systems, depending on system design and coating specification.
