Fluke Wide Angle IR Smart Lens for Ti450, Ti400, Ti300, Ti200; ideal for electrical and building inspections - in a tight space or viewing a large area. When working in a tight space, get a wide field of view that lets you see a larger target from a close distance. See an entire bank of switchgear cabinets in tight quarters, or see more components through an IR window. View the entire side of a building without getting too far away, or inspect roofs quicker than with a standard lens by viewing a much larger area at a time. Avoid the hassle of sending in your camera to calibrate with the lens — with smart lenses you can just attach the lens to any compatible camera and start taking images. Made of 100 % diamond-turned germanium with an engineered coating, the most efficient available material to transmit energy to the detector.
