Description
Technical field
The present invention relates to a kind of optical module, particularly one and utilize optically-variable zoom lens group to change infrared laser characteristic, reach the spot size zoom mode of not visible light source.
Background technology
At present, 850nm plane radial type laser feature, adopts utilizing emitted light, has equidirectional directive property, and the little and concentration of energy of the angle of divergence of light beam, close to desirable directional light, has therefore limited the scope of light source applications.
Tradition LED light source, not only power consumption is large and illumination light cannot be projected at a distance, light source is diversity and more cannot effectively utilizes what remote, also because the characteristics of luminescence of laser causes light beam too concentrated, hot spot irradiated area scope is too narrow and small, is applied in the field of not visible optical illumination therefore limited.In current existing solution, once utilized Fresnel (Fresnel) lens combination to do secondary optics zoom, but need to continue to increase when its scope, and only can reach to splice plural element.The another mechanical zoom mode that uses, easily occurs that hot spot zoom process occurs the obvious slack situation of segmentation on continuing.Adopt the principle of the electrodeless zoom of current zoom lens to utilize the high-penetrability of laser and linearity to complete hot spot zoom in the collocation that utilizes zoom lens, from focusing apart from different of Fresnel (Fresnel) lens before, zoom lens relies on quick-replaceable to carry out Fresnel (Fresnel) lens to realize hot spot zooming transform, but realize lens focus conversion by the zoom ring of push-and-pull or rotating lens, within the scope of lens zoom, focal length can stepless transformation, be that any focal length in zooming range can be used, this has just created condition for the variation that realizes not visible optical illumination.
Summary of the invention
For above defect, the invention provides a kind of infrared laser illuminating module, with current industrial technology, cost of manufacture is very nearly the same with LED really, more effectively solve luminance difference, illumination distances is near, volume is large, life of product is short, and has supplied the light filling market vacancy between 80-300 rice.Therefore, the present invention can replace LED infrared lamp, becomes best light source leading products, except realizing 24 hours continuously monitoring, has more that illumination distances is far away, long service life, and night vision imaging effect is good, disguised high, thoroughly solves the features such as a night vision illumination difficult problem.The night vision monitoring places such as public security, the administration of justice, bank, prison, oil field, engineering construction, forest, maritime affairs, customs, harbour, railway, airport, frontier defense, army, road, factory building, community, square, warehouse are widely used at present.
For reaching above object, the present invention has adopted following technical scheme: a kind of infrared laser illuminating module, comprise main body, described main body is fixed on fixed mount, described main body comprises optical lens group, lens mount, be provided with laser (VCSEL) illuminating module at the burnt module light inlet of optically-variable, described laser (VCSEL) illuminating module one side is fixed on fixed mount, for the vertical light inlet of light emitting source, opposite side is connected with the inner face of radiating fin, radiating fin outer face is provided with light source driving board, described laser (VCSEL) illuminating module and optical lens group, the focal length of lens mount is located on same axis.
Lasing fluorescence module of the present invention comprises 850nm plane radial type laser chip, and described chip is pressed semiconductor 5630 packaged type encapsulation.Described optical lens group can change focal position by moving lens interior lens, change the length of lens focus, and can change camera lens visual angle size, thereby the amplification that realizes image is dwindled.Described light emitting source is 850nm infrared laser light source.The luminous frequency spectrum halfwidth of described light emitting source is < 1nm.Described laser (VCSEL) illuminating module comprises one or more plane radial type laser chips.Described fixed mount adopts aluminium base.Described optical lens arrangement of mirrors head has one group of convex lens sheet, and mobile interior lens changes focal position; The described optical lens group composition that is structure as a whole; Described optical lens group material is optical glass, has focus adjustable parts, and keeps focus to change on same axis.
Adopt after above technical scheme, zoom lens of the present invention, in the situation that not changing irradiation distance, can change hot spot scope by variation focal length, is therefore very beneficial for monitoring and the application of public place.Because a zoom assembly can doublely be born the responsibility, several focus the effect of assembly, have not only reduced the quantity of framework when framework equipment, have also saved the expenditure on replacing time and cost.
Below in conjunction with accompanying drawing, the invention will be further described.
