Abstract

The present application discloses an optical system with high pixels. Along the optical axis direction, a first lens group, an aperture stop, a second lens group and an image surface are sequentially arranged from the side of the object plane to the side of the image plane. The lens group has negative refraction power and its position can move along the optical axis direction, and the second lens group has positive refraction power and its position can move along the optical axis direction. A high-pixel optical system of this application can achieve 12 million pixels, the shortest focal length fW≤4mm; the longest focal length fT≥17.5mm; the shortest focal aperture F#W≤1.4; the longest focal aperture F#T≥3.1 ; The total length of the optical system TTL≤90.5mm and the shortest optical back focus BFL≥9.0 The imaging surface of the system is 1/1.8", the system can be widely used in security, unmanned driving, unmanned aerial vehicle, vehicle-mounted systems and other fields with ultra-high pixel requirements.

Description

technical field [0001] The present application relates to an optical system, in particular to a high-pixel optical system. Background technique [0002] The development of face-to-face optical imaging technology is changing with each passing day. From the VGA level of 30 to 40 million pixels in the late 1990s, through the megapixels at the beginning of this century, the level of 200 to 300 pixels five or six years ago, and now to the current 6 million Pixels, even 4K and 8 megapixel levels, it can be seen that its development law is constantly developing towards high-end pixels; [0003] On the other hand, the highest chip technology is now generally up to 10 million pixels; whether it is the mobile phone industry, digital SLR industry, vehicle industry or drone industry, high-end products basically require imaging of more than 10 million pixels; and the current security industry , due to its special product size and application requirements, there are very few 10-million-p...
