Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of measuring lens, specifically relates to a transparent sucking disc of lens measuring power meter. BACKGROUND

[0002] In the early lens measuring power meter work, usually use simple transparent sucking disc. These sucking discs mainly rely on manual operation to adsorb lens. The operator needs to squeeze the sucking disc with hand, exhausts air, thereby generates negative pressure and adsorbs lens. This mode has many problems. First, the negative pressure generated by manual squeezing is not stable enough. In the measuring process, due to the slight change of external environment, such as temperature change leads to air volume change or slight vibration, can make the negative pressure in the sucking disc change. For example, in the environment of slightly high temperature, the air in the sucking disc expands, and the negative pressure decreases, and the lens can be loose, which affects the measuring accuracy. Secondly, the precision of manual operation is low. The strength and operation mode of different operators are different, so that the adsorbing position and angle of the lens on the sucking disc are difficult to guarantee consistent. For high-precision lens measurement, such as progressive multifocal lens or high refractive index lens measurement, the deviation of position and angle will directly lead to large error of measurement result.

[0003] Lens position deviation: manual placement of lens is prone to inaccurate position. The operator needs to position the lens by experience and naked eye, and it is difficult to guarantee that the optical center of the lens is completely coincident with the measuring center of the power meter. When measuring progressive multifocal lens, slight deviation of lens position will lead to large error of measured degree in different areas, and the accurate power value of each part of the lens cannot be accurately obtained. Lens angle deviation: manual placement of lens can also cause the inclination of lens. Due to the instability of human hand operation, the lens on the sucking disc can have a certain angle error. This is very unfavorable for high-precision optical lens measurement, because the angle deviation will change the light path of light passing through the lens, so that the deviation of parameters such as astigmatism axis position detected by the power meter occurs. For example, the axis position deviation of astigmatism lens will lead to the inaccuracy of measured astigmatism degree and actual degree, which affects the final optometry and lens fitting result.
