Description
Technical field
The present invention is with regard to a kind of optical lens, saturating especially with respect to a kind of diffraction optics with diffractive optical structure
Mirror.
Background technology
In recent years, with the evolution of electronics industry and flourishing for industrial technology, various electronic installations
Design develops progressively towards direction that is light, being easy to carry about with one, is applied to whenever and wherever possible move business with sharp user
The purposes such as business, amusement or leisure.For example, image capture unit miscellaneous is just being widely used in respectively
The field of kind, such as portable electronic devices such as intelligent mobile phone, Wearable electronic installation, which has small volume
And the advantage being convenient for carrying, user is able to take out and carry out image capture when having use demand at any time and store up
Deposit, or be further transmitted through among mobile network is uploaded to internet, not only with important commercial value, more
The daily life of general masses is allowed more to add color.
In view of this, the volume for being applied to the optical lens of image capture unit also increasingly reduces, not only its mirror
The thickness requirement more and more thinner of piece, the diametric requirements of eyeglass are also less and less.Fig. 1 is referred to, which is existing light
Learn the part-structure sectional view of camera lens.The assembling work of optical lens 9 be can be seen that from the sectional view shown in Fig. 1
Sequence is loaded down with trivial details, and the multiple eyeglasses 91 for for example constituting optical lens 9 all must be just obtained using extra structural member 92
To be mounted in lens barrel (barrel) 93, and spuious light trap must also be set in such as lens barrel 93 disappear
To avoid veiling glare by eyeglass 91, these obviously make optical lens 9 not to piece (stray light baffle) 94
Easily it is miniaturized.Further, since most eyeglass 91 is formed through the processing procedure of ejection formation, therefore
The buckling deformation for easily producing during shaping or residual stress, this also increases the degree of difficulty of assembling.
And illustrate, in order to lift the reliability of the optical lens after microminiaturization 9, there is many and group
The details of pass of pretending more needs to be included into consideration, for example：(1) how to lift the eyeglass after being assembled to lens barrel 93
91 structural strength；(2) how to improve or avoid warpage of the eyeglass 91 produced by during shaping in advance
Deformation or residual stress, are beneficial to the assembling of subsequent optical camera lens 9 and avoid being led because refractive index is changed
The light path of cause makes a variation and causes unnecessary or burst aberration；And how (3) simplify the group of optical lens 9
Into structure (as spuious light trap disappear piece 93 or to fixing len 91 in the structural member 92 of lens barrel 93), to subtract
The assembling procedure of few optical lens 9.
Furthermore, a kind of existing diffraction optical lens 8 (diffractive lens) are suggested and apply in optics at present
Camera lens 9 is corrected aberration (aberration) or eliminates dispersion (dispersion) to lift image quality, such as.Please
Refering to the surface structure schematic diagram that Fig. 2 and Fig. 3, Fig. 2 are existing diffraction optical lens, Fig. 3 is shown in Fig. 2
The generalized section of diffraction optical lens.Shown in Fig. 2 and Fig. 3, the outward appearance of diffraction optical lens 8
Too big difference is had no with the outward appearance of general eyeglass 91, but which has been internally formed to by diffraction optical lens
8 light beam carries out the diffraction grating 81 of modulation, with further amendment aberration or elimination dispersion.
Only, above-mentioned diffraction optical lens 8 are only simple lens structure, that is, overall structure is all effective light
Student movement area, if therefore diffraction optical lens 8 are applied to into the optical lens after microminiaturization, then it is above-mentioned with
The related details of assembling still needs to be included into consideration, and such as diffraction optical lens 8 must utilize extra structural member
Just it is able to be mounted in the lens barrel of optical lens.
Additionally, diffraction optical lens are limited to its wavelength available scope in the past, therefore it is limited in application.
However, due in the market to depth camera (depth camera), flight time span camera (time of
Flight camera, TOF camera), infrared surveillance system (CCTV) and thermal imaging system (thermal imager)
Etc. optical technology product growing interest, its market scale can the phase, and the ripple used by these optical technology products
It is long mostly interval interior in specific wavelength, therefore diffraction optical lens become gradually to be taken seriously with its application.
Explanation more than comprehensive, how through the structure to diffraction optical lens itself and processing procedure improved with
Increase its wavelength available scope and avoid which that buckling deformation or residual stress are produced during shaping, together
When can also via it is such improvement simplify optical lens composition structure and lifted be assembled to spreading out after lens barrel
The structural strength of optical lens, and then the assembling and the lifting of overall efficiency of convenient subsequent optical camera lens are penetrated,
Become an important problem.
