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:
| Lens Assembly Code | Effective Focal Length (EFL) | F# | Field of View (FOV) | Sensor Size | Sensor Pixel Size | Datasheet |
| X61201 | 2.0 mm | 1.0 | 90°(H) x 66°(V) | 256 x 192 px | 12 µm | Datasheet |
| X61321 | 3.2 mm | 1.1 | 50°(H) x 37°(V) | 160 x 120 px | 17 µm | Datasheet |
| X61361 | 3.6 mm | 1.1 | 50°(H) x 37°(V) | 256 x 192 px | 12 µm | Datasheet |
| X62361 | 3.6 mm | 1.0 | 50°(H) x 37°(V) | 256 x 192 px | 12 µm | Datasheet |
| X61971 | 9.7 mm | 1.0 | 27°(H) x 20°(V) | 384 x 288 px | 12 µm | Datasheet |
| X61A51 | 15.0 mm | 1.0 | 25°(H) x 19°(V) | 384 x 288 px | 17 µm | Datasheet |
