Description
Technical Field
The utility model belongs to the technical field of aspheric surface lens profile curvature measures technique and specifically relates to indicate an aspheric surface lens securing device.
Background
The aspheric surface is a surface deviating from the spherical surface, and the aspheric optical element is adopted in the optical system, so that the number of the optical elements can be reduced, the weight can be reduced, the size of the system can be reduced, the instrument structure can be simplified, aberration can be corrected, the imaging quality can be improved, the degree of freedom of optical design can be increased, and the cost can be reduced, therefore, the aspheric optical element is widely applied and rapidly developed in modern optical systems. Particularly, along with the increase of DV requirements for monitoring, vehicle-mounted and sports in recent years, the rapid growth of products such as laser televisions and optical communication drives the demand of aspheric lenses to keep growing at a high speed. Meanwhile, higher requirements are also placed on the detection of the surface shape parameters of the optical aspheric lens. Because of the particularity of the aspheric lens, the contact type contourgraph is a face type detection mode which is most suitable for large-scale production. But contact contourgraph is when measuring, and the measured object is directly placed on placing the platform, presses at the measured object with a gland that opens the cross hole afterwards and fixes, and measuring probe and measured object contact to produce the effort, because the power of gland is unstable, uncontrollable, measuring probe probably drives the aspheric lens and takes place the displacement, lead to measuring result to appear the deviation, every lens of surveying simultaneously all need take off the gland and cover, complex operation, inefficiency.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide an aspheric lens piece securing device fixes aspheric lens piece through the atmospheric pressure mode, and it is stable, controllable and convenient operation, is favorable to the later stage to improve accuracy and the measurement of measurement aspheric lens piece profile curvature.
