Abstract
A fixture for optical elements includes a washing bar, a holder and a vacuum pump. The washing bar includes an inner channel and a connecting portion in communication with the inner channel. A hole is formed in the washing bar for communicating with the inner channel. The holder connects with the washing bar. The holder has a holding surface communicating with the hole. The holding surface has a shape corresponding to a peripheral surface of the optical elements to be held. The vacuum pump is connected with the connecting portion. The vacuum pump is configured for vacuum the washing bar so as to effectively suck the one of the optical elements on the holding surface. The present fixture can hold optical elements firmly and does not damage the optical elements.
