FLIR’s New Photon 640 LWIR thermal imaging cameras are now available. The Photon 640 is based on the same camera design architecture as the Photon 320, which means the same rapid turn-on time, wide operating temperature range, high shock rating, and overall reliability customers have come to expect from the Photon family. This latest addition to the remarkably successful Photon product line offers several new features and capabilities:

· 640x480 resolution (640x512 for PAL) with 25 µm pixels

· Shorter thermal time constant to reduce image blurring and smearing

· Field-switchable between NTSC and PAL video formats

· 4x (and 2x) digital zoom modes

Along with a lens-lens core version, three lens options are supported: 19mm; 35mm; and 50mm. See the Optics Table tab for detailed lens information. Additional lenses are planned.
