P/N: 55001-0303
Rev.: 35207
General description
The FLIR A655sc is an excellent choice for those working in R&D and require the highest frame rates
and 640 × 480 pixel resolution. When using the camera in R&D, it is highly recommended to use the
FLIR ResearchIR software from FLIR Systems.
The camera is equipped with a 45° lens.
Key features:
• Affordable.
• 16-bit 640 × 480 pixel images at 50 Hz.
• Start-and-stop recording in FLIR ResearchIR using digital input.
• Windowing mode: 640 × 240 pixels at 100 Hz or 640 × 120 pixels at 200 Hz.
Typical applications:
• Mid- or high-end industrial R&D.
