Teledyne FLIR A35 / A65 Features

​Extremely Affordable and Compact

Teledyne FLIR’s Ax5 Series models are low-cost thermal imaging temperature sensors that are ideal tools for monitoring temperatures in automation or machine vision.

​High Thermal Sensitivity and Image Quality

The Teledyne FLIR Ax5 Series produces high quality thermal images that can show temperature differences as small as 50 mK. Record crisp 640 x 512 pixel thermal images with the Teledyne FLIR A65, or for less precise applications, the A35 generates a 320 x 256 pixel thermal image that still allows you to easily track temperature changes.

​GigE Vision Standard Compatibility

GigE Vision is a camera interface standard developed using the Gigabit Ethernet communication interface. GigE Vision is the first standard to allow for fast image transfer using low-cost standard cables, even over long distances.

​GenICam Protocol Support

The goal of GenICam is to provide a generic programming interface for all types of cameras. This protocol also makes it possible to use third party software with the camera.

​14-bit Temperature Linear Output

Allows for non-contact temperature measurement within any third party software. A built-in Gigabit Ethernet connection allows real time 14-bit image streaming to a computer.


Possible to configure one camera to be master and others to be slave(s) for applications that call for more than one camera to cover the object or for stereoscopic applications.
