Description
FLIR A6481 50 mm Motorized Lens
The FLIR A6481 50-mm motorized lens is the longest-range lens among the three standard focal lengths in the series. It operates in the mid-wave infrared (MWIR) band with a motorized FPO bayonet mount, designed for FLIR’s cooled R&D and scientific cameras, and allows for remote focus adjustment via software or a controller.
It covers the 3.0–5.0 µm wavelength range with an f/2.5 aperture—the same as specified in the A6481 data sheet—so it maintains the instrument’s sensitivity and measurement accuracy. It is the go-to choice when measuring small or distant objects without sacrificing resolution on the target.
Main features
- 50 mm focal length in the MWIR band from 3.0 to 5.0 µm; the longest focal length of the three.
- Aperture f/2.5, matching the standard lens on the A6481.
- Motorized focus, remotely adjustable via software or a controller.
- 4-tab motorized FPO bayonet mount, the standard for FLIR cooled cameras.
- Interchangeable with the other focal lengths in the series: 17, 25, 50, 100, and 200 mm.
Common applications
- Measuring Small or Distant Objects
- Non-Destructive Testing and Active Thermography
- R&D and Laboratory Test Benches
Compatibility
FLIR specifies it for its R&D and scientific cameras, including the A67xx MWIR, A85xx MWIR, X68xx MWIR, X69xx MWIR, and X85xx MWIR series. The A6481 data sheet lists this focal length among its motorized lenses and specifies a FLIR FPO-M mount.
