Fluke FLK-LENS/25MAC2 is intended for observing heat distribution on printed circuit boards and very small electronic components. Macro optics help examine the heating location, heat buildup and dissipation in a component. The working distance is measured in millimeters, so position the camera and target securely. The manufacturer specifies detail down to 25 microns, or 18 microns with a TiX580. The precalibrated Smart Lens requires no individual calibration to a compatible camera. Its germanium lens has a coating for infrared transmission. This card lists compatibility with TiX580 and Ti480 PRO. The lens is supplied separately from the thermal camera and mounting fixtures.
