FAQ
What is an athermalized IR lens?

An athermalized IR lens is designed to maintain focus across varying temperatures without needing manual adjustment. It automatically compensates for thermal expansion and contraction, which can affect image clarity in infrared imaging applications.

What is the significance of the 3.6mm focal length?

The 3.6mm focal length offers a wide field of view, which is ideal for applications such as thermal imaging, security surveillance, and industrial inspections where a broader coverage area is required.

How does the athermalized design improve performance?

The athermalized design compensates for temperature-induced focus shifts, maintaining sharpness and clarity in a wide range of environmental conditions. This is especially important for devices used outdoors or in environments with fluctuating temperatures.
