Abstract
The utility model discloses threaded type optical fiber focus lamp in a kind of microminiature, it includes light conducting cylinder, described light conducting cylinder front end is provided with lens, described light conducting cylinder rear end is provided with fiber-optic fixing-hole, described light conducting cylinder inwall has fine and closely woven screw thread, described light conducting cylinder hypomere outer wall has extenal fixation screw thread, and described light conducting cylinder hypomere upper surface has fixing step, and described fiber-optic fixing-hole middle has diaphragm aperture.The light conducting cylinder inwall of this ultraphotic fibre focus lamp has more delicate screw thread, after peroxidating extinction processes, absorbing ability strengthens, the absorbable unnecessary veiling glare dissipated, totally without veiling glare around luminous point after lens light gathering, eliminate the veiling glares such as aperture halation, detecting distance is remote, improves the accuracy of detection.
Description
Technical field
This utility model relates to focus lamp technical field, is specially threaded type optical fiber focus lamp in a kind of microminiature.
Background technology
Having veiling glare around luminous point after traditional common optical fiber focus lamp optically focused, i.e. aperture or halation, the reddest
Light becomes apparent from, and the accurate and stability of impact detection, light itself has certain dispersion angle after diaphragm aperture, and these are all
The accuracy of impact detection.
Summary of the invention
The purpose of this utility model is to provide threaded type optical fiber focus lamp in a kind of microminiature, to solve above-mentioned background
The problem proposed in technology.
For achieving the above object, this utility model provides following technical scheme: in a kind of microminiature, threaded type optical fiber gathers
Jiao Jing, its composition includes: light conducting cylinder, and described light conducting cylinder front end is provided with lens, and in described light conducting cylinder, rear end is provided with optical fiber
Fixing hole, described light conducting cylinder inwall has fine and closely woven screw thread, and described light conducting cylinder hypomere outer wall has extenal fixation screw thread, described
Light conducting cylinder hypomere upper surface has fixing step, and described fiber-optic fixing-hole middle has diaphragm aperture.
Preferably, threaded type optical fiber focus lamp in described microminiature, described fine and closely woven screw thread is extinction screw thread.
Compared with prior art, the beneficial effects of the utility model are: threaded type optical fiber focus lamp in this microminiature
Fiber-optic fixing-hole inwall has more delicate screw thread, after peroxidating extinction processes, absorbing ability strengthens, and absorbable unnecessary dissipates
Veiling glare, totally without veiling glare around luminous point after lens light gathering, eliminates veiling glare and aperture halation, and detecting distance is remote, improves
The accuracy of detection.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model sectional view.
In figure: 1, extenal fixation screw thread, 2, light conducting cylinder, 3, fine and closely woven screw thread, 4, lens, 5, diaphragm aperture, 6, fiber-optic fixing-hole.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: threaded type optical fiber focus lamp in a kind of microminiature,
Including light conducting cylinder 2, light conducting cylinder 2 front end is provided with lens 4, and in light conducting cylinder 2, rear end is provided with fiber-optic fixing-hole 6, and light conducting cylinder 2 inwall has
Having fine and closely woven screw thread 3, light conducting cylinder 2 hypomere outer wall to have extenal fixation screw thread 1, light conducting cylinder 2 hypomere upper surface has fixing step, optical fiber
Fixing hole 6 middle has diaphragm aperture 5, and fine and closely woven screw thread 3 is extinction screw thread, and this extinction screw thread processes through peroxidating extinction
Screw thread, this oxidation extinction treatment technology is the routine techniques of Treatment of Metal Surface.
Operation principle: the fine and closely woven screw thread 3 of light conducting cylinder 2 inwall, after oxidation processes, absorbing ability strengthens, absorbable unnecessary
The veiling glare dissipated, totally without veiling glare around luminous point after lens light gathering, eliminates veiling glare and aperture halation, detecting distance
Far, improve the accuracy of detection.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
