Auxiliary device for cleaning the surface of optical lens

Abstract

The invention discloses an auxiliary device for optical lens surface cleaning. The auxiliary device comprises a base, a plane reflective mirror and a light absorption device arranged on the base, anda cover body covering outside the plane reflective mirror and the light absorption device, wherein the plane reflective mirror is inclined at the angle ranging from 40 degrees to 50 degrees; a reflecting surface is arranged toward the inclined upper part; a taper hole is horizontally formed in the light absorption device; the light absorption device is arranged on the reflecting side of the planereflective mirror; an opening of the taper hole faces the plane reflective mirror; the taper angle of the taper hole of the light absorption device ranges from 10 degrees to 50 degrees; and a light inlet hole is formed in the position, located right above the plane reflective mirror, on the top part of the cover body. According to the auxiliary device for optical lens surface cleaning provided bythe invention, the influence on the microscopic examination due to a reflected light of an operating table board is avoided through absorbing and eliminating an incident light penetrating through an optical lens to be cleaned, and operating personnel can clearly observe smudges, dust, scratches and the like on the optical lens to be cleaned, so that a cleaning and maintenance effect is effectivelyensured. The auxiliary device for optical lens surface cleaning provided by the invention is ingenious in design, low in manufacturing cost, and convenient to use and operate.

Description

technical field [0001] The invention relates to the technical field of electronic endoscope maintenance, in particular to an auxiliary device for cleaning the surface of an optical lens. Background technique [0002] The surface cleanliness of the optical lens in the image transmission lens of the electronic endoscope is relatively high, and the cleanliness of the lens surface directly affects the imaging effect of the image transmission component. Therefore, it is often necessary to clean and maintain it, and it is generally operated under a microscope. However, when the lens is observed under a microscope, it is affected by the reflected light of the background, which makes the observation surface of the optical lens too bright, making it difficult for the operator to observe and wipe the dirt, specks and scratches on the surface of the lens, so that it cannot be effectively cleaned. Difficult to meet maintenance standards. Contents of the invention [0003] The technic...
