FLIR IR Lens 6° LR (7-8.5 µm) with Case (GF77)
The GF77 Gas Find IR Series offers two types of lenses-low-range (LR) and high-range (HR)-in a standard 25° field of view or as a 6° telephoto lens. The LR lens has a built-in 7-8.5 µm wavelength filter for visualizing methane, nitrous oxide, propane, sulfur dioxide, R-134a, and R-152a. The HR lens filters the 9.5-12 µm wavelength for visualizing sulfur hexafluoride, ammonia, and ethylene. Both the LR and HR lenses are compatible with the GF77 camera body.
