Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of cutting edge lens ink coating technology, especially to a cutting edge lens ink coating jig. BACKGROUND
[0002] In optical systems, one important factor affecting the optical quality of lenses is stray light. In order to improve the clarity and contrast of imaging, it is necessary to eliminate stray light and obtain lenses with the best optical quality. The commonly used method is to coat the edges of the lenses with ink. The light extinction ink is a black or gray ink that can be applied to the edges of the lenses. The ink can absorb stray light outside the effective aperture, significantly reducing lens reflection and glare.
[0003] Currently, the conventional method for coating lenses is as follows: first, fix the lenses on an adsorption device, and then use a special brush to evenly coat the edges of the lenses with ink that has been properly mixed. However, this coating method has many drawbacks, for example, for cutting edge lenses, this coating method is easy to coat ink on the optical surface of the lenses, thereby contaminating the optical surface and causing the lenses to be scrapped. Another example is that the adsorption device often has weak suction force, and when the brush is used to coat ink, the lenses are easily knocked off when the brush hits the lenses, causing the ink to overflow onto the optical surface.
