Embodiment Construction

[0017] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0018] Such as figure 1 As shown, a superstar-level high-definition large image surface fixed-focus lens includes a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, and a first lens arranged in sequence along the optical axis from the object side to the image side. The fifth lens 5, the sixth lens 6, the seventh lens 7, the eighth lens 8, the ninth lens 9 and the tenth lens 10, the first lens 1 is a convex-concave negative power lens, and the second lens 2 is The concave-convex negative refractive power lens, the third lens 3 is a concave-convex positive refractive power lens, the fourth lens 4 is a bi-convex positive refractive power lens, and the fifth lens 5 is a bi-convex positi...

Abstract

The invention provides a high-definition and large-image-surface super starlight prime lens. The high-definition and large-image-surface super starlight prime lens comprises a convex-concave negative-focal-power first lens, a concave-convex negative-focal-power second lens, a positive-focal-power third lens, a biconvex positive-focal-power fourth lens, a biconvex positive-focal-power fifth lens, abiconcave negative-focal-power sixth lens, a biconvex positive-focal-power seventh lens, a concave-convex negative-focal-power eighth lens, a biconvex positive-focal-power ninth lens and a convex-concave positive-focal-power tenth lens which are sequentially arranged from the object space and the image space along an optical axis. The high-definition and large-image-surface super starlight primelens has the advantages that the 10 specially arranged lenses are used, lens parameters are creatively designed, and the prime lens is super-large in light transmission quantity and cable of especially satisfying the monitoring requirements under complex conditions; in addition, under the premise that the F1.0 large light transmission quantity is kept, imaging quality is increased, and the prime lens supports wide field angle of 110 degrees; meanwhile, resolving power can be guaranteed when the prime lens is used in an environment of 40-70 DEG C, and imaging requirements can be satisfied.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a fixed-focus lens with super starlight level high-definition large image surface. Background technique [0002] With the increasing popularity of security monitoring facilities, the monitoring environment and screen requirements are getting higher and higher, and monitoring screens with higher pixels and greater light flux are required. At present, image sensor manufacturers have launched 1 / 1.8" large image area low-illumination image sensors, which have better light-receiving ability. However, there are almost no lenses that can match it on the market, so the corresponding ultra-low-illumination F1 is developed. 0's 1 / 1.8" lens is necessary. Contents of the invention [0003] The present invention provides a fixed-focus lens with super starlight high-definition large image surface, which overcomes the shortcomings in the prior art and is more compatible with a large image surf...
