Description
Technical field
The present invention relates to a kind of lens, particularly relate to a kind of aberration compensation (chromaticaberration) lens.
Background technology
Progress along with modern science and technology, many optical articles are also constantly weeded out the old and bring forth the new, no matter be that brightness enhancement layer, CD-ROM, the VCD-ROM of the module backlight of handset displays panel or camera display panel, the optical read head (optical read head) of DVD-ROM all must use lens (lens).In addition, present digital camera (Digital Still Camera, DSC) and digital camera (Digital VideoCamera, DVC) in, lens also are indispensable important.In above-mentioned optical articles, lens will directly have influence on the fiduciary level of product operation for the processing of light source.In the general optical articles, if when adopting white light as light source, regular meeting has the phenomenon of aberration to produce.
Seeing also shown in Figure 1A, is the synoptic diagram that produces the aberration phenomenon behind the existing known lens of white light source process.Traditional lens 10 have a light entrance face 12, a light-emitting face 14 and an optical axis 16.When the optical axis 16 that is parallel to lens 10 as white light W is injected by the light entrance face 12 of lens 10, white light W after lens 10 refraction, can be again by light-emitting face 14 outgoing of lens 10, at this moment, white light W can reflect into the light of three primary color wavelength bands, is respectively a blue light B, a green glow G and a ruddiness R.Because the wavelength difference of blue light B, green glow G and ruddiness R, position b, the g, the r that make blue light B, green glow G and ruddiness R refract to respectively on the optical axis 16 are neither identical, thereby produce the aberration phenomenon.
This aberration phenomenon then is relevant with chromatic dispersion (dispersion) degree of lens, generation for fear of this kind aberration phenomenon, as a result the special lens combination (lens systems) of anaberration (achromat) or multiple anaberration (apochromaticdoubles) in response to and give birth to, and this kind lens combination is made of lens different more than two, to eliminate this aberration phenomenon.
Seeing also shown in Figure 1B, is the synoptic diagram of the lens combination of existing known elimination aberration phenomenon.Should have the lens (flint lens) 120 that known lens combination 100 comprises lens (crown lens) the 110 and one flint glass material of a crown glass material now, wherein the crown glass material has a lower dispersity compared to the flint glass material.The lens 110 of above-mentioned crown glass material comprise a light entrance face 112, light-emitting face 114 and an optical axis 116, when white light W is parallel to optical axis 116 and is injected by the light entrance face 112 of lens 110, this lens combination 100 can intersect at same position through the lens 110 of crown glass material and lens 120 refraction light R, the B afterwards of flint glass material, so can compensate the aberration phenomenon that is produced between blue light B and the ruddiness R.
It should be noted that, because existing known lens combination 100 need be cooperated by lens different more than two, and the specification of every lens 110,120 and arrangement pitches all can influence the aberration compensation effect of this lens combination 100, the assembly error of therefore any lens combination 100 slightly, the scale error of lens itself, or this lens combination 100 is subjected to vibrations or when heavily falling, for its aberration compensation effect great influence is arranged all.Therefore, make that also the output of lens combination 100 or assembling yield (lowyield rate) are on the low side.
This shows that above-mentioned existing aberration compensation lens still have defective, and demand urgently further being improved.In order to solve the problem that the aberration compensation lens exist, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that above-mentioned existing aberration compensation lens exist, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, in the hope of founding a kind of novel aberration compensation lens, can improve general existing aberration compensation lens, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
