Abstract
The utility model discloses a large-aperture granite and glass composite spherical and aspherical reflector manufacturing method and a reflector manufactured by the method. An optically planar, spherical and aspherical reflector is processed by firmly gluing a molded optical glass mirror blank and a granite mirror body through glue and processing the upper surface of the optical glass mirror blank by using the conventional optical glass processing technology. The reflector mainly comprises the optical glass mirror blank and the granite mirror body, so that single large-size optical glass is not used, and the high optical performance of the reflector is retained; and therefore, a good solution is supplied to reducing the costs of the large-aperture and high-performance planar, spherical and aspherical reflectors. Furthermore, the mirror body is made of granite, and the expansion coefficient of the granite is substantially the same as that of the glass, so that the reflector is high in production technology, and the stability and the reliability of the composite reflector are close to those of the full glass reflector.
Description
Technical field
The utility model belongs to applied optics field, particularly relates to a kind of heavy caliber grouan glass combined type sphere and non-spherical reflector.
Background technology
Solar simulator is the light source that is used for producing simulated solar irradiation, is the key equipment that on production line, uses in the test high power concentrator electrification component performance.The Spectral matching property of the simulated solar irradiation of its generation, transient stability, homogeneity, collimation and illuminance etc. need meet relevant international standard with the approaching degree of the performance of natural sunshine.Producing bigbore parallel beam needs bigbore collimating optical system, normally adopts heavy caliber sphere or non-spherical reflector to make collimator objective.Because the difficult acquisition of large scale optical glass and expensive is so be difficult to promoted the use of.It is material that metallic aluminium casting article are adopted in external at present proposition, utilizes the large-sized numerical control fine turning lathe to come this reflector body of processing and manufacturing, and on reflecting surface, pastes the reflectivity that highly reflecting films improve minute surface.But the surface working poor performance of aluminium, thermal expansivity is higher, and the cost of aluminum casting article is higher.Recently we have proposed use grouan replacement aluminium and have made the plane mirror body, sphere and aspheric surface collimating mirror body.But this solution obtainable optical property certain limitation is still arranged, also can't intend with the performance of optical glass.
The utility model content
The purpose of the utility model is to provide a kind of optical property height, lower-cost heavy caliber grouan glass combined type sphere and non-spherical reflector.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The utility model is a kind of according to heavy caliber grouan glass combined type sphere and non-spherical reflector, and it is made up of optical glass mirror embryo and grouan mirror body; Described optical glass mirror embryo and grouan mirror body are bonded into as a whole securely.
Described optical glass mirror embryo is spherical shell shape, and described grouan mirror body is dome shape, and described spherical shell shape optical glass mirror embryo and dome shape grouan mirror body are complementary.
Described optical glass mirror embryo is made up of an optical glass.
Described optical glass mirror embryo is spliced to form by polylith optical glass.
Described optical glass mirror embryo is made up of plane optical glass or polylith plane optical glass.
After adopting such scheme; Because the utility model is glued together securely with the optical glass mirror embryo and the grouan mirror body and function adhesive glue of moulding; And the concave of the concave spherical surface shape of optical glass mirror embryo and grouan mirror body is complementary; Avoided using the high optical property of monolithic large scale optical glass and maintenance product, thereby be that the cost that reduces heavy caliber high-performance sphere and aspherics catoptron provides good solution.In addition; It is the mirror body that the utility model adopts grouan; Itself and glass swelling coefficient are roughly the same, and being prone to of large scale grouan material obtains and ripe forming processing technology is arranged, and adds the surface working performance that optical glass is fabulous; This makes the product processes of the utility model reliable and stable, product percent of pass is higher, for obtaining high-performance heavy caliber sphere and aspherics catoptron a kind of technological approaches of novelty is provided.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Embodiment
Like Fig. 1, shown in Figure 2, the utility model is a kind of heavy caliber grouan glass combined type sphere and non-spherical reflector, and it is made up of optical glass mirror embryo 1 and grouan mirror body 2.
The middle part 11 of described optical glass mirror embryo 1 is spherical shell shape (as shown in Figure 4), and the middle part 21 of grouan mirror body 2 is spherical shape (as shown in Figure 3).The spherical shell shape at the middle part 21 of described optical glass mirror embryo 1 middle part, 11 spherical shell shapes and grouan mirror body 2 is complementary.
Described optical glass mirror embryo 1 can be made up of a bigger optical glass, also can be made up of the optical glass of the less splicing form of polylith.
In addition; The catoptron of the utility model also can be for plane; That is: described grouan mirror body and optical glass mirror embryo all are plane; Described plane optical glass mirror embryo and plane grouan mirror body are complementary, and plane optical glass mirror embryo and plane grouan mirror body are bonded into as a whole securely.
This optical glass mirror of the utility model embryo 1 can be used to produce heavy caliber beams focusing or collimation (index path is as shown in Figure 5) with sphere and non-spherical reflector that grouan mirror body 2 is combined into.Especially it can be used as the critical component-high performance optical alignment object lens of Application of Solar Energy field needed high power concentrator power generation module group assembly property testing apparatus solar simulator.Also be expected object lens as the heavy caliber autocollimator; Or the application scenario that need produce light beam focusing or collimation in other optics and the laser device with sphere and non-spherical reflector.
As shown in Figure 1, the manufacturing approach of the utility model, it may further comprise the steps: grouan slab middle part is processed into the grouan mirror body 2 (as shown in Figure 3) of needed dome shape in (1); (2) adopt the technology of " glass plate flexure " will have certain thickness optical flat to be shaped to the optical glass mirror embryo 1 (as shown in Figure 4) of spherical shell shape, and the shape of optical glass mirror embryo 1 spherical shell convex shape and dome shape grouan mirror body 2 is complementary; (3) with spherical shell shape optical glass mirror embryo 1 and the suitable adhesive glue (as shown in Figure 2) glued together securely of grouan mirror body 2 usefulness; (4) with traditional optical glass processing technology the 1 upper surface processing and manufacturing of optical glass mirror embryo is become optical spherical surface or non-spherical reflector.
The emphasis of the utility model just is: adopt the mirror body of processing with the roughly the same grouan material of optical glass mirror embryo glass swelling coefficient.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this; The roughly the same material of all employings and optical glass mirror embryo glass swelling coefficient is as the mirror body, and adopts gluing method and glass cement to synthesize the situation of an integral body, all should still belong in the scope that the utility model patent contains.
