The MWIR cooled continuous zoom thermal imager for radiation characteristic measurement is configured with a Stirling-cooled medium-wave detector with a resolution of 640×512 and a pixel size of 15µm, and is equipped with continuous zoom lens of 40mm～200mm and 50mm～800mm respectively. The thermal imager is furnished with various intelligent image processing algorithms such as adaptive NUC, image noise filtering, automatic enhancement, and multi-temperature adaptation. The infrared lens features electric

 zoom, electric focusing, and one-key focusing functions. It enables continuous zooming and clear imaging throughout the entire range; during zooming, the optical axis consistency is ≤2 pixels, and the optical axis repeatability is ≤1 pixel. With advantages like excellent grayscale stability and a wide grayscale response range, it can be applied to various platforms such as photoelectric theodolites and photoelectric turrets.

• The optical axis remains stable during continuous zooming, with a consistency error not exceeding 2 pixels.

• It features a wide grayscale response range of no less than 2500–13500, and the response linearity is better than 1.5%.

• It has super-strong environmental adaptability and can perform stable measurements in high-temperature and low-temperature 

• environments for a long time.

• It measures diverse radiation characteristics, matched with a continuously rotating polarizer, 4 types of attenuation filters, and 4 

• types of narrowband filters.
