Infrared Optical System Structure

Traditional infrared optical structures can be divided into three types: refractive, reflective, and catadioptric. Modern new infrared optical structures can be divided into three types: refractive-diffractive hybrid system, off-axis three-mirror system, and dual-FOV optical system.

What are the general design principles of the mounting base of the infrared optical lens?

The bore diameter of the mounting hole of the infrared lens (D) should be larger than the outer diameter of the lens (d), and generally, for optic lenses, D is larger than d by 0.4 mm. On special occasions where there is a high demand of coaxality or athermalized design of the lens, the size of the mounting hole should be determined according to specific situations. The gap between them is for easier installation, and some silica gel can be filled in the gap to keep the lens from damage.

The Analysis of Selecting Infrared Bands

The advantage of infrared sensor engineering design plays an important role in the performance of the whole system. Infrared imaging technology with wavelengths ranging from 3 to 5 μm and 8 to 12 μm has always been the focus of the development of infrared imaging technology. Which of these two bands is superior in long-range detection? This issue has been under discussion since the 1970s, showing its importance.
