Abstract
This application discloses an imaging device with an operating temperature range of -40℃ to +60℃, comprising a 4K high-definition lens and a detector for receiving images captured by the 4K high-definition lens. The 4K high-definition lens has a focal length of 50mm, a relative aperture of 1.25, and operates in dual bands: 0.43~0.656μm and 0.7~1μm. The detector has a pixel count of 3840×2160 and a pixel size of 2.9μm. The 4K high-definition lens employs a heat-free design using domestically produced spherical glass, resulting in a simple, compact structure and small size. It utilizes a high-dispersion material lens and a low-dispersion material glass bonded together to achieve dispersion matching. The combination of different lenses and the rational allocation of optical power ensure excellent optical performance. Furthermore, it is suitable for imaging in high-brightness daytime and low-light nighttime environments and can switch bands for imaging, ensuring clear images both day and night.
