Abstract

The invention relates to the technical field of lens machining, in particular to a manufacturing method for a resin lens for a telescope. The resin lens is composed of a resin lens substrate, a scraping-resistant film and a waterproof film. The resin lens has good anti-blue light performance, and by adding blue light transforming powder, blue light harmful to the eye balls is removed through transformation. An abrasion-resistant layer is added, so that the protective performance of the lens is changed. The lens has waterproof performance, and rainwater is prevented from staying on the surfaceof the lens. The physical strength of the lens for the telescope is effectively improved, the quality of the lens is improved, the use effect of the lens is improved, and the service life of the lensis prolonged.

Description

technical field [0001] The invention relates to the technical field of lens processing, in particular to a method for manufacturing a resin lens for a telescope. Background technique [0002] A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. The refraction of the light through the lens or the reflection of the light by the concave mirror make it enter the small hole and converge into an image, and then pass through a magnifying eyepiece to be seen. Also known as "telescope". [0003] The first function of the telescope is to enlarge the opening angle of distant objects, so that the human eye can see details with smaller angular distances. The second function of the telescope is to send the light beam collected by the objective lens that is much thicker than the diameter of the pupil (up to 8 mm) into the human eye, so that the observer can see faint objects that were originally invisible. After more than...
