The FLIR FlexView™ Dual Field-of-View (DFOV) infrared lens combines two optical perspectives—42° extra-wide and 24° wide—into a single lens assembly, allowing thermographers to switch views instantly without physically changing lenses. FlexView® dual field of view infrared lens (42°/24°), f=10/17 mm, with lens case. For FLIR T500-Series, T800-Series, and Exx-Series cameras.
You never have to change your lens in the field again—with the push of a button—instantly switch from extra wide views for added safety, wide views for scene context, or tighter views for accurate temperature measurement.
This design helps users rapidly scan large equipment or inspection areas using the wider 42° view, then shift to the narrower 24° view for clearer temperature measurement and improved detail on specific targets.
The lens integrates two different optical prescriptions (10 mm and 17 mm focal lengths) in one housing, enabling the camera to toggle between fields of view mechanically or electronically while maintaining radiometric accuracy for precise thermal analysis.
Built for professional inspection workflows, the FlexView DFOV lens improves efficiency by eliminating the need to carry multiple lenses, reducing the risk of contamination or damage during field changes, and ensuring operators can capture both large-area context and small hot-spot details from the same position.
