Product information "Thermal Imaging Lens Assemblies"

Effective Focal Length EFL 3.2-19.0 mm; f/# 1.0, 1.1; FOV 13.9°x10.4°-50°x37°; Recommended Detector Resolution 160x120-384x288 Pixel; Recommended Detector Pixel Size 12, 17 µm; Working Distance 3.07-12.0 mm

For immediate use in thermal imaging cameras, GH Optics' infrared precision molded aspheric lenses are available pre-assembled in aluminium/plastic housings with a range of thread sizes.

By using precision molded aspherics, this series of thermal imaging lens assemblies offers a cost advantage, especially in larger quantities. The assemblies are optically athermalized in a temperature range from -45°C to +85°C and available with different coatings, such as anti-reflection (AR), high-density (HD) or short wave blocking (SWB). Typical applications for these infrared thermal imaging lens assemblies are thermography, security & surveillance and diagnostics.

Within our series of thermal imaging lens assemblies you find seven standard models, each one optimized for a certain detector size:
