1. Technological innovation and performance breakthrough of optical systemThe long-wave infrared (LWIR) zoom lens takes the 8-14μm spectral range as its working core, and realizes the visualization of thermal signals through the cross-innovation of material science and optical engineering. Different
The athermal lenses mainly realizes the day-night conversion through the infrared filter, that is, opening the filter in the daytime to block the infrared rays, so that it can only sense the visible light. In the case of night vision or poor lighting conditions, the filter will stop working, and the
The difference between short wave infrared, near infrared, medium wave infrared and long wave infraredNear Infrared (NIR): Wavelength between 0.75-1.4 microns, defined by the absorption of water, usually used in optical fiber communication due to the low attenuation rate in silica glass. Wavelengths
