Description
Technical Field
The invention relates to a non-contact optical flat clamp, in particular to a method for realizing the surface non-contact storage and clamping of a tested piece through a clamp frame unit, a push rod unit, a storage base unit and a mounting base unit, which are arranged, and is suitable for the storage and clamping of an optical lens.
Background
The multi-surface transparent optical parallel plate has very high surface quality, the difference of the fluctuated peaks and valleys of the surface is in the micron level or even the nanometer level, and the multi-surface transparent optical parallel plate is applied to various fields. The storage and holding of such plates is one of the difficulties in the measurement of their surface topography. The reason is that: the high-precision optical flat plate has high surface quality, so that the surface of the flat plate is prevented from being manually or mechanically contacted to the greatest extent possible during clamping and storing, because the contact can possibly damage the surface of the flat plate. Moreover, the flat plate is made of fused quartz material, is brittle and can be completely damaged once being carelessly slid off. It is therefore of great interest to design a holder and storage device that can hold and hold the flat panel without damage.
At present, most of the applied clamps and storage systems adopt fixed clamps, the optical flat plate is taken from the storage box by manually using two hands, and after the optical flat plate is placed on the clamps, the compression heads of the clamps are rotated to compress a tested piece. The drawbacks of this approach are quite evident: (1) in the process of manually taking the tested piece, the surface of the tested piece is easy to damage; (2) in the process of manual taking and clamping, because only the outer edge part can be taken, but the diameters of a plurality of measured pieces are larger, accidents or mistaken touch of fingers are easily sent in the process, and the measured pieces are damaged; (3) in the process of taking and clamping a large-diameter measured piece, because the surface of the large-diameter measured piece is strictly prohibited to be in direct contact, the clamping head and the clamping position are difficult to adjust in the clamping process, and as a result, when the measured piece is subjected to interference measurement, the inclination of an acquired interference pattern is large and fringes are dense, so that the inclination of the part needs to be eliminated in the topography measurement technology, and the measurement cost is increased.
