FLIR 24° Lens (f=17 mm) with Case

FLIR 24° Lens (f=17 mm) with Case

The FLIR 24° Lens (f = 17 mm) is a standard-field-of-view infrared lens designed for FLIR professional thermal cameras. It provides a balanced perspective—wide enough to capture entire assets while still delivering detailed thermal measurement accuracy—making it ideal for routine inspections across electrical, mechanical, and building applications.

This interchangeable IR lens delivers a 24° × 18° field of view, enabling technicians to inspect equipment from a safe distance while still resolving small temperature differences. With a 17 mm focal length and high-sensitivity optics, it captures clear thermal imagery across a variety of inspection environments.

Key Features

• Standard-angle thermal lens optimized for general-purpose inspections
• 24° × 18° FOV provides a practical balance between coverage and detail
• 17 mm focal length for accurate thermal measurement and imaging performance
• Close focusing capability (down to ~0.15 m) supports near-range inspection tasks
• AutoCal™ lens recognition allows compatible FLIR cameras to automatically detect and calibrate the lens when attached
