Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an optical structure of a 90° steering adapter with a C-MOUNT interface. The technical solution adopted is: use a relay lens assembly instead of a glass rod, increase the optical length, and change the structure of the steering prism assembly , so that the combination of the relay lens assembly and the steering prism assembly forms a positive image, realizing the connection between the adapter and the camera system through the C-MOUNT interface, and overcoming the defect that the existing 90° steering adapter structure cannot realize the connection of the C-MOUNT interface

Embodiment 1

[0011] Embodiment 1: the distance between the entrance pupil 11 and the front group 12 of the relay lens is 2 mm, the distance between the rear group 13 of the relay lens and the incident surface of the steering prism assembly 2 is 1 mm, the front group 12 of the relay lens and the rear group of the relay lens The distance of 13 is 10mm, the focal length of relay lens front group 12 is 6m, the focal length of relay lens rear group 13 is 12mm, the angular magnification of relay lens assembly 1 is 0.5 times, the focal length of imaging assembly 3 is 30mm, and the 90° turn The combined focal length of the adapter is 15mm, and the distance L between the entrance pupil 11 and the optical axis of the imaging component 3 is 30mm.

[0012] The working principle is: the approximately parallel light of ±7° emitted by the endoscope passes through the turning of the relay lens assembly 1 to form an inverted image, and is emitted in parallel by the rear group 13 of the relay lens, and the b...

Embodiment 2

[0013] Embodiment 2: the distance between the entrance pupil 11 and the front group 12 of the relay lens is 5 mm, the distance between the rear group 13 of the relay lens and the incident surface of the steering prism assembly 2 is 3 mm, the front group 12 of the relay lens and the rear group of the relay lens The distance of 13 is 15mm, the focal length of relay lens front group 12 is 10m, the focal length of relay lens rear group 13 is 10mm, the angular magnification of relay lens assembly 1 is 1 times, the focal length of imaging assembly 3 is 20mm, and the 90° turn The combined focal length of the adapter is 20 mm, and the distance L between the entrance pupil 11 and the optical axis of the imaging component 3 is 35 mm.

Embodiment 3

[0014] Embodiment 3: the distance between the entrance pupil 11 and the front group 12 of the relay lens is 8 mm, the distance between the rear group 13 of the relay lens and the incident surface of the turning prism assembly 2 is 5 mm, the front group 12 of the relay lens and the rear group of the relay lens The distance of 13 is 20mm, the focal length of relay lens front group 12 is 15m, the focal length of relay lens rear group 13 is 7.5mm, the angular magnification of relay lens assembly 1 is 2 times, the focal length of imaging assembly 3 is 15mm, 90° The combined focal length of the steering adapter is 30 mm, and the distance L between the entrance pupil 11 and the optical axis of the imaging component 3 is 40 mm.

[0015] Embodiment 2 and Embodiment 3 have the same working principle as Embodiment 1, and will not be repeated here.

[0016] The adapter optical structure scheme of the present invention is especially suitable for a 90° turning endoscope camera adapter conne...

Abstract

The invention relates to an optical structure of a ninety-degree deflecting adapter of a C-MOUNT interface, and belongs to the technical field of image displaying. The optical structure of the ninety-degree deflecting adapter of the C-MOUNT interface is applied to an endoscope camera shooting system. A relay lens assembly is used for replacing a glass rod and increasing the optical length, the structure of a deflecting prism assembly is changed, in this way, the relay lens assembly and the deflecting prism assembly are combined to form an erect image, and the adapter can be connected with the camera shooting system through the C-MOUNT interface; the defect that an existing ninety-degree deflecting adapter structure can not achieve C-MOUNT interface connection is overcome, and the optical structure is particularly suitable for the ninety-degree deflecting endoscope camera shooting adapter of C-MOUNT connection and is applied to urological department examination and operations.

Description

technical field [0001] The invention relates to an optical structure of a 90° steering adapter of a C-MOUNT interface, which is applied to an endoscope camera system and belongs to the technical field of image display. Background technique [0002] The endoscope imaging adapter is a component that connects the endoscope and the imaging device, and its function is to image the image formed by the endoscope onto the imaging element of the imaging device. For applications such as urology, a 90° steering optical adapter is required. The existing 90° steering adapter is integrated with the camera device. This structure limits the application range of the camera device. From the perspective of application requirements, it is required An adapter for connecting a camera device through a C-MOUN interface. The existing 90° turning adapter is composed of a glass rod, a right-angle roof prism and an imaging component. The core of its technical solution is to realize a 90° turning of th...
