FLIR 42° Lens (f=10 mm) with Case
The FLIR 42° IR Lens (f = 10 mm) with case is a wide-angle interchangeable infrared lens designed to expand the field of view of compatible FLIR thermal imaging cameras. It enables users to inspect larger areas quickly while maintaining accurate temperature measurement and image quality.
This lens provides a 42° × 32° field of view, allowing technicians to capture more of a scene without needing to step back from the target—making it particularly useful in confined spaces or when inspecting large equipment. With its 10 mm focal length, the lens is optimized for scanning broad targets such as electrical panels, motors, tanks, heat exchangers, and building envelopes during predictive maintenance or troubleshooting inspections.
The accessory is compatible with a wide range of FLIR thermal cameras—including models in the T-Series (e.g., T530, T540, T560, T840, T865) and Exx-Series (e.g., E75, E85, E86, E95, E96)—and can be swapped quickly thanks to automatic lens recognition and calibration features that maintain measurement accuracy.
Supplied with a protective carrying case, the lens is designed for safe transport and field durability, ensuring reliable operation in industrial and maintenance environments.
