Abstract
The invention relates to a method for processing non spherical surface lens for transmission of infrared line. The inventive method comprises steps of: inputting mathematical curve into digital control machine according the non spherical surface lens for processing; processing the mathematical curve into basic shape via digital control machine with macromolecule material of high transparence rate. Employing polishing machine to process traces on the basic shapes; hardening and performing surface lighting process with hardener, then drying in a drying machine.
Description
Technical field:
The present invention relates to a kind of machining method of aspherical lens that is used for infrared transmission, relate in particular to a kind of infrared transmission communication facilities reception camera lens of (being called for short FSO), belong to the aspheric lens processing technique field.
Background technology:
Aspheric lens results from 1966, eyeglass grinds is shaped as para-curve, quafric curve, cubic curve or high order curve, and correction factors such as the differing of camera lens, aberration, spherical aberration the time have just been considered in design, usually a slice aspherical lens just can reach the effect that a plurality of spheric glasses are corrected aberration, therefore can reduce the quantity of eyeglass, the light reflection of make the precision of camera lens better, sharpness is better, color rendition is more accurate, camera lens is interior is minimized, and the camera lens volume is also corresponding to be dwindled.Aspheric lens has the advantages that change is doubly high, object distance is short, aperture is big.Become the doubly high kind that can simplify camera lens, the object distance weak point can be applied in the closely occasion of shooting, aperture greatly then can adapt to the darker place of light, has been widely used in optical fields such as camera, video camera, projector, VCD/DVD now, almost spreads all over each corner of life.
Aspheric lens mainly contained following three kinds of job operations in the past:
1. employing underhand polish, this job operation cycle is long, and it is unified that quality is difficult to keep;
2. employing import equipment, the import equipment multi-million dollar, so that the processed and molded product unit price is more expensive;
3. employing injection moulding method;
Because the difficulty of processing of aspheric lens is bigger, these three kinds of processing modes only are fit to the camera lens of diameter between 3mm-40mm.
Infrared transmission communication facilities (be called for short FSO) is to transmit and receive laser beam aloft by optical device to realize communication, and optical lens is the device of most critical wherein, and used camera lens has following characteristics among the FSO:
1, it is big to receive diameter of lens: generally between 100-160mm, the camera lens combined reception of also useful four diameter 80mm, its effect only is equivalent to the camera lens of a diameter 160mm.
2, energy efficiency wants high: to receive infrared energy, not needing has too high requirement to aberration, imaging definition, but the efficient of optical system wants high, and the loss between generally transmitting and receiving is not more than 2-3dbm.
3, structure is simply light as far as possible.
The aspheric mirror head material that is used for infrared transmission at present is a glass, the eyeglass less than 100 mm dias of the mostly mode of underhand polish, or specialized equipment processing.
Summary of the invention:
The objective of the invention is to invent a kind of diameter of producing greater than 100mm, convenient for production, the machining method of aspherical lens that is used for infrared transmission that cost is low.
For realizing purpose of the present invention, technical scheme to be solved by this invention is a kind of machining method of aspherical lens that is used for infrared transmission, it is characterized in that adopt through the higher macromolecular material of infrared efficient and carry out cutting working method, it comprises the following steps:
1-1. the aspheric lens mathematic curve by required processing is input in the numerically-controlled machine;
1-2. cutting:
Adopt through the higher macromolecular material of infrared efficient and be processed into basic configuration through numerically-controlled machine mathematic curve on request;
1-3. polishing:
On basic configuration, adopt buffing machine that cutter trade is polished;
1-4. sclerosis:
With rigidizer the workpiece that processes is done sclerosis and any surface finish processing, in dryer, dry then.
The present invention's employing is carried out cutting working method through the higher macromolecular material of infrared efficient can reach the purpose of manufacturing diameter greater than the 100mm aspheric lens, and macromolecular material is lighter than glass, can satisfy infrared transmission communication facilities (being called for short FSO) the light requirement of structure.
Advantage of the present invention is:
1, cost is low, and the method cost of manufacture is less than 500 yuan;
2, can produce the aspheric lens of diameter in enormous quantities greater than 100mm;
3, the camera lens external form is not necessarily circular, is convenient to assemble the FSO equipment of new structure;
4, can change the mathematic curve of camera lens easily, satisfy different request for utilizations;
5, light.
Embodiment
The invention will be further described below in conjunction with embodiment.
Embodiment 1
The ball face camera lens that diameter of employing PMMA macromolecular material manufacturing is 150mm, ball face camera lens mathematic curve by the 150mm diameter is input in the numerically-controlled machine, at first use numerically-controlled machine, mathematic curve cut on request becomes basic configuration, on basic configuration, adopt buffing machine that cutter trade is polished then, with rigidizer the workpiece that processes is done sclerosis and any surface finish processing at last, in dryer, dry then.
