The large-aperture short-wave camera mainly consists of a front fixed group, a zoom group, a middle fixed group, a compensation group, a focusing group, a rear fixed group, and a short-wave core. The lens focal length is 40mm~320mm (640×512@15μm, F2.2). It adopts a universal cam-type opto-mechanical structure and precision transmission design, with component integration realized through later visual assembly and adjustment technology and advanced servo control technology.The optical design adopts a continuous zoom design and undergoes temperature calibration to achieve clear imaging during zooming across the entire focal length range. During the zoom process, the overall optical axis consistency is no more than 2 pixels, and the optical axis repeatability accuracy is no more than 1 pixel. It has excellent protection and environmental adaptability, and can be applied to various platforms for field use such as photoelectric theodolites and photoelectric turrets.

• Adaptive non-uniformity correction technology, digital noise reduction, and automatic dimming technology.

• High optical axis stability, with optical axis consistency ≤ 2 pixels.

• Large-aperture and large-aperture design.

• Sealed design, with survival capability in harsh climatic environments.
