FLIR's new 7° lens is so light and portable, you'll be amazed how easy it is to use for regular surveys. But what's really impressive is the incredible thermal image clarity and exceptional temperature data you'll be able to capture from farther away. With 3.6× magnification, it's ideal for scanning small or distant targets such as overhead power lines and substation equipment. Add greater safety and reliability to your thermal inspections with the new 7° lens option, made especially for FLIR T640 and T620 cameras.
