Description
Technical field
The present invention relates to the optical-mechanical field, be specifically related to utilize point light source light-emitting and make light by single negative lens and the positive combined light path of balsaming lens, and then obtain collimating the method for directional light.
Background technology
In scientific experiment, the application of collimation source of parallel light is very extensive.From using and the consideration of cost angle, be that volume is little, in light weight, cost is low, easy realization simple in structure to the requirement of light source.Require on the basis more than satisfying, it is high that the light depth of parallelism of light source is wanted, and light source needs replaceable to satisfy in the experiment requirement to the light of dissimilar, different light intensity and different spectral coverage simultaneously.Simple and easy source of parallel light commonly used adopts structure as shown in Figure 1.Optical routing spot light and convex lens are formed, and spot light is placed on the concave lens focus place, and the scattered light that sends pools directional light through convex lens.The advantage of this light source is easy realization simple in structure, but in actual applications, because the reflection of the light of light tube inwall and lens position error produce a large amount of veiling glare and halation, the depth of parallelism of emergent ray is lower, is difficult to satisfy practical application to the instructions for use of directional light.
Summary of the invention
The present invention exists the depth of parallelism of emergent ray low for solving the conventional lighting sources structure, can't solve the heat radiation of light source simultaneously and have the problem that can't eliminate veiling glare, and a kind of light supply apparatus of outgoing collimation directional light is provided.
A kind of light supply apparatus of outgoing collimation directional light comprises radiator fan, spot light structure, mounting flange and lens light barrel structure; Described spot light structure comprises halogen tungsten lamp and diaphragm, and the lens light barrel structure comprises single negative lens, single negative lens microscope base, positive balsaming lens, positive balsaming lens microscope base, lens barrel and adjustment thread bush, and mounting flange comprises light source adpting flange and light tube adpting flange; Described halogen tungsten lamp is installed in the housing of sealing, end at housing arranges radiator fan, the housing inboard arranges diaphragm, on the other end fixed light source adpting flange of housing, single negative lens is installed on single negative lens seat, and single negative lens seat is connected with the light source adpting flange by adjusting thread bush, and described positive balsaming lens is installed on the positive balsaming lens seat, described positive balsaming lens seat is installed on the lens barrel, and lens barrel is connected with the light source adpting flange by light tube adpting flange.
Operation principle of the present invention: the present invention includes spot light structure and lens light barrel structure.Utilize halogen tungsten lamp to do the light that spot light sends the directive all directions, and filter out the light of all the other directions except optical path direction by diaphragm.Because most of light fails to enter in the light tube, in structure, can produce certain heat, influence optics stability, so also comprise radiator fan in the spot light structure, strengthen the circulation of air in the light path, unnecessary heat sheds.The single negative lens of The latter and positive balsaming lens are combined takes the photograph formula object lens light path far away, makes the scattered light of spot light pool directional light and sends from the light tube.This light tube has shortened the common required focal length of single use convex lens, makes more compact structure, can effectively eliminate veiling glare and aberration simultaneously, improves the light quality of sending.
Scattered beam sends from halogen tungsten lamp, through the diaphragm eliminate stray light, through the formula object lens light path far away of taking the photograph of single negative lens and positive balsaming lens composition, obtains collimating directional light again.Positive balsaming lens can effectively be eliminated the aberration of light with respect to single convex lens, improves the directional light quality.Simultaneously, the use of single negative lens can be shortened the focal length that uses single positive balsaming lens, and eliminates the veiling glare in the light path to a certain extent.Though halogen tungsten lamp is not desirable spot light, filament has certain volume, because the combination depth of focus of single negative lens and positive balsaming lens is bigger, can effectively eliminate the influence of filament.Owing to have error in processing and the assembling process, spot light, single negative lens and positive balsaming lens can be adjusted three's relative position by guiding mechanism not on ideal position, until producing the higher directional light of the depth of parallelism.The present invention utilizes spot light and specific light path to realize converging of scattered beam, produce the collimation directional light, and eliminate the aberration in the light communication process effectively, by the distance between helicitic texture adjustment lens and light source and lens, improve the directional light quality, solve the light source heat radiation problem simultaneously.Consider practical application, this light-source structure compactness, in light weight, cost is low, is easy to change spot light, external convenience.
Beneficial effect of the present invention:
One, the present invention adopts single negative lens and the taking the photograph of lens combination of just joining formula light path far away, the scattered light of spot light can be pooled directional light, has eliminated veiling glare and aberration in light path, improves the directional light quality.Because this light path has bigger depth of focus, can effectively eliminate imperfect spot light to the adverse effect of the depth of parallelism that emits beam, improve light path to the adaptability of Different Light.Shortened focal length simultaneously, made structure compacter.
Two, the present invention arranges and adjusts structure and comprise (adjusting thread bush, threaded ring and microscope base etc.), can adjust light source, single negative lens and positive balsaming lens three's relative position easily, control light quality.
Three, to do the spot light cost with halogen tungsten lamp low in the present invention, and volume is little, the power supply power supply easily realizes.Can change light source easily and then obtain directional light of different nature according to different demands.
Four, the present invention adopts radiator fan, has solved the heat dissipation problem of light source, makes light path more stable.Compact overall structure, in light weight, cost is low and external fixing simple.
