Example Embodiment

[0022] The technical solution will be further described below in conjunction with the accompanying drawings of the specification.

[0023] Such as figure 1 and image 3 Shown is a miniature endoscopic lens, including a sensor chip 6, a lens group, and a mounting assembly for mounting the lens group. The mounting assembly includes a lens barrel 2 and a lens holder 1. The lens holder 1 and the lens barrel 2 pass through threads. connection. The lens group includes a first lens 3 and a second lens 5, and a Mylar sheet 4 is arranged between the two lenses.

[0024] The nominal diameter of the thread of the lens barrel 2 and the lens holder 1 is 3.5mm, and the thread pitch is 0.25mm. The friction force between the lens barrel 2 and the lens holder 1 is ensured.

[0025] This embodiment uses the sensor chip OV9734, the imaging size is 400*400*1.4um, the pixel size is 1.4um*1.4um, the pixel resolution is 400*400, the image area range is 1.02 mm, and the imaging circle size is larger than...

Abstract

The invention discloses a micro endoscope lens. The micro endoscope lens includes a sensing chip, a lens set and an installation assembly used for installing the lens set; the installation assembly includes a lens barrel and a lens support; the lens set is installed in the lens barrel; the sensing chip is arranged on the image space side of the lens set; and the lens barrel is in threaded connection with the inner side of the lens support. The substantive effects of the micro endoscope lens include as follows: the micro endoscope lens is simple in structure and flexible in assembling; the difference between product individuals can be reduced; imaging quality can be guaranteed; production costs can be reduced; and the micro endoscope lens is high in reliability, large in structural intensity and long in service life.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to a miniature endoscope lens. Background technique [0002] Capsule endoscope is a kind of endoscope made in the shape of capsule. It is a medical instrument used to check the human intestinal tract. To help doctors diagnose patients with digestive tract diseases. Capsule endoscopes for bladder are currently in great demand, but there is a lack of suitable and high-quality products. [0003] The utility model with the publication number CN207529018U discloses a microcapsule endoscopic lens, including a mirror tube and a lens group, the maximum image height of the lens group is 2.9mm, and the effective focal length of the lens group is 1.04mm; the lens group is from the object side to the image side It includes the first lens, the second lens, the aperture stop, the third lens, the fourth lens and the fifth lens in sequence, wherein the focal lengths of the first lens, the second lens, t...
