Abstract

The invention discloses a lens height testing fixture. The lens height testing fixture comprises a testing base plate, a lens fixing seat is fixed on the upper surface of the testing base plate, a rectangular notch is formed in the middle of the lens fixing seat, a downward pressing handle is embedded into the rectangular notch and fixed in the rectangular notch through a torsional spring, the upper surface of the downward pressing handle abuts against an upper face plate of the lens fixing seat, a lens containing groove used for containing a lens is formed in the contact position of the lens fixing seat and the downward pressing handle, upward restoring force of the downward pressing handle is generated under the action of the torsional spring, and the lens contained in the lens containing groove abuts against a height testing probe. According to the lens height testing fixture, the lens can be placed in the lens containing groove formed in the lens fixing seat, a protecting film layer is arranged in the lens containing groove to protect the surface of the lens, the lens does not need to be held by hand during the testing process, the testing precision is improved, and a good application prospect is achieved.

Description

technical field [0001] The invention relates to a lens lens height testing jig, belonging to the technical field of lens lens testing. Background technique [0002] A lens lens is an optical component widely used in the technical field of optical fiber communication. With the rapid development of optical communication, the requirements for lens quality are getting higher and higher. At present, for the lens lens height test, the test is still carried out manually through a micrometer. Due to the small size of the lens lens, it is not convenient to hold it, resulting in low test accuracy, and it is time-consuming and laborious. Contents of the invention [0003] The purpose of the present invention is to overcome the problem of low test accuracy, time-consuming and labor-intensive problems in the existing lens lens height test, due to the small size of the lens lens, which is inconvenient to hold. The lens lens height testing jig of the present invention can place the len...
