Step 2：By the way of spraying SiO is uniformly coated in spherical optics element surface2Aerosol, then pass through test
Equipment tests optical parametric, repeatedly coats SiO2Aerosol reaches design requirement；
Step 3：Finally by heat curing process, make SiO2Aerosol is transformed into homogeneous transparent SiO2Material and and bottom
Spherical optics element combine together.
Further, described test equipment is ZYGO test equipments.
Further, the optical element such as described spherical optics element or concave surface, convex surface, cylinder.
Preferably, described spraying uses SiO2Spraying equipment, described SiO2Spraying equipment can be that single shower nozzle also may be used
To be the multiple shower nozzles of multiple caliber while work.
Preferably, described heat curing process can be that single thermograde can also be varied as desired in producing difference
The heat curing process of effect.
As another embodiment of the present invention, present invention also offers a kind of aspherical optical element making side
Method, it is characterised in that comprise the following steps：
Step 1：The aspherical module of aspherical optical element is made, is subsequently filled SiO2Aerosol；
Step 2：Then spherical optics element is placed, makes SiO2Aerosol is dispersed in spherical optics element table
Face；
Step 3：Finally by heat curing process, make SiO2Aerosol is transformed into homogeneous transparent SiO2Material and and bottom
Spherical optics element combine together.
Further, the optical element such as described spherical optics element or concave surface, convex surface, cylinder.
Preferably, the aspherical module can be that metal material can also be monocrystal material.
Preferably, the aspherical module can by it is single or it is as needed be designed to various combination in a manner of battle array
Row.
Preferably, described heat curing process can be that single thermograde can also be varied as desired in producing difference
The heat curing process of effect.
Using above-mentioned technical proposal, aspherical optical element preparation method of the present invention, have the advantage that for：
Using SiO2The characteristic of aerosol, aspherics member is made with reference to traditional optical process technology improvement mould pressing process high-volume
Part, production efficiency and flexibility can be significantly improved, effectively reduces production cost.
