Athermal LWIR Objectives: Owl-IR Series
This series of LWIR (long-wave infrared) athermal objectives covers the 8-14µm spectral region and are available in 50 mm, 100 mm, and 150 mm focal lengths. They have an image diagonal of 21.8 mm, greater than 85% transmission, and a threaded mount type.
Owl-IR LWIR objectives have been designed to provide high optical MTF performance and are capable of providing radiometric grade imaging. The 50 mm standard model has a 24.9o full field of view and a 30.0 mm back focal length. The 100 mm standard model has a 12.4o full field of view and a 30.0 mm back focal length as well. The 150 mm LWIR objective in the OWL-IR series has an 8.3o full field of view and a back focal length of 40.3 mm.
Custom LWIR objectives are also available. For more information, download the available datasheet.
