Abstract

The invention relates to a bubble-free refraction liquid applying device and a bubble-free refraction liquid applying method. The device is composed of a vacuum pump, multiple air tube segments, a filter, a filter flask, a vacuum chuck, a pasting plate and a piece under test. The vacuum pump, the filter, the filter flask and the vacuum chuck are connected in series by the multiple air tube segments; an adsorption port of the vacuum chuck naturally fits a small hole on the external surface of the pasting plate; two surfaces of the piece under test respectively fit the inner surfaces of two laying plates to form a gap; a dropper is located over the circumferential gap of the piece under test and the pasting plates, and the refraction liquid is continuously added at the edge of the gap through the dropper, so that the refraction liquid is absorbed in the gap between the pasting plates and the piece under test. The method comprises the following steps of: while applying the refraction liquid, starting the vacuum pump to form negative pressure in the gap between the pasting plates and the piece under test, continuously dropping the refraction liquid at the edge of the gap, so as to make the refraction liquid be absorbed in the gap, and finishing the applying of the refraction liquid, until the whole gap is full of the refraction liquid.

Description

technical field [0001] The invention relates to a smearing device and a smearing method of a bubble-free refraction liquid, which is particularly suitable for the smearing of the refraction liquid in the high-precision measurement of the uniformity of optical materials. Background technique [0002] In the high-precision measurement of the uniformity of the optical blank material, it is necessary to apply a layer of refraction fluid that matches the refractive index between the test piece and the mounting plate to ensure good light transmission and reliable measurement accuracy. Bubbles that can be identified by the interferometer cannot be included in the refraction liquid layer, otherwise the measurement data of the corresponding part will be lost and the measurement accuracy will be affected. [0003] At present, there are two main methods of applying this type of refraction fluid: one is to apply the refraction fluid on the surface of the test piece, and then attach two ...
