Abstract
The utility model discloses a hard tube mirror with LED illumination, LED paster install between first objective and second objective and lie in the position corresponding to the edge of first objective rear end, guarantee the required angle of vision and imaging resolution, compare the scheme of placing at first objective front end, can avoid sheltering from the visual field, carry high resolution, with the edge design of first objective for plano -convex lens, can assemble the light of the too big LED paster of angle that gives out light to imaging system is avoided influencing, and illumination brightness can be strengthened, the utility model discloses compare with the device of current market sale, because the utility model relates to an in reduced by a preceding screening glass, consider from the fund angle that the cost reduces to some extent.
Description
Technical field
The utility model relates to a kind of hard tube mirror with LED illumination, belongs to the technical field of industry and medical treatment detection apparatus.
Background technology
Endoscope both can be used as the medical optical instrument of diagnosis and treatment, also can be used as industrial detection equipment, has been approved widely and apply in society of today.The inner structure of tradition hard tube mirror as shown in Figure 1, comprises the mirror pipe be made up of scope pipe and outer telescop, optical fiber, the imaging system be made up of objective lens, excellent mirror group and eyepiece group, light cone, main mirror and rear screening glass etc.The novel hard tube mirror now occurred adopts the method that single mirror pipe designs and throw light in LED front end, and compared with traditional hard tube mirror, significant cost reduces, and can reduce hundreds of unit.After using LED to replace optical fiber to throw light on, brightness uniformity significantly increases, and improves contrast simultaneously, optical transfer function is obtained and promotes, because this increasing resolution.But adopt LED front end means of illumination to there is limitation in structural design, for the rigid pipe endoscope that diameter is less, the size of LED Luminous paster and the relation of maximum luminous power are the technical bottlenecks existed at present.On current visual field, minimum dimension paster luminous power is little, although can be placed in foremost, can block imaging viewing field.Large scale LED light power is large, although can reach illumination requirement, placing illumination foremost seriously can block visual field, cannot carry out normal observation.And LED lighting angle is about 120-140 degree, the field of view angle of endoscope is about 70-80 degree, and therefore LED lighting angle is much larger than field of view angle, and unrealized optical energy charging divides utilization.
Summary of the invention
The utility model object is to provide a kind of hard tube mirror with LED illumination, under the prerequisite of field angle ensureing objective lens, improves resolution, reduces costs.
A kind of hard tube mirror with LED illumination provided by the utility model, the imaging system comprising main mirror, supplying channels, mirror pipe, LED paster, wire and be made up of objective lens, excellent mirror group, eyepiece group and spacer tube.The wire that LED paster is drawn passes the rear end of connectivity gap to mirror pipe, and leads to outside main mirror by supplying channels, and it is characterized in that, described objective lens comprises the first object lens and the second object lens.Described LED paster to be installed between the first object lens and the second object lens and to be positioned at the position corresponding to edge of the first object lens rear end.
The utility model has following beneficial effect:
1, LED illumination mode cost provided by the utility model is lower, is positioned over the back edge position of the first object lens, the field angle needed for guarantee and imaging resolution, compares and the scheme being placed on the first object lens front end, can avoid blocking visual field, improves resolution;
2, be plano-convex lens by the first object lens edge designs, the light of LED paster excessive for lighting angle can be converged, thus avoid affecting imaging system, and can brightness of illumination be strengthened.
3, compared with the device that the utility model and Vehicles Collected from Market are sold, owing to decreasing a front screening glass in the utility model design, consider from fund angle, cost decreases.
Accompanying drawing explanation
Fig. 1 is traditional hard tube mirror inner structure schematic diagram;
Fig. 2 is the objective lens schematic diagram of the hard tube mirror with LED illumination of the present utility model;
Fig. 3 is the overall diagram of the hard tube mirror with LED illumination of the present utility model;
Wherein, 1-objective lens, 2-rod mirror group, 3-eyepiece group, 4-spacer tube, 5-wire, 6-mirror pipe, 7-LED paster, 8-supplying channels, 9-main mirror, 10-first object lens, 11-second object lens; (defining towards observed object side is front end, the other end, be namely rear end towards observer side).
Embodiment
As shown in Figure 3, a kind of hard tube mirror with LED illumination of the present utility model, the imaging system, LED paster 7 and the wire 5 that comprise main mirror 9, supplying channels 8, mirror pipe 6 and be made up of objective lens 1, excellent mirror group 2, eyepiece group 3 and spacer tube 4.Wire 5 to the rear end of mirror pipe 6 through connectivity gap, conveniently leads to outside main mirror 9, is also provided with supplying channels 8 by the wire 5 that LED paster 7 is drawn.Objective lens 1 comprises the first object lens 10 and the second object lens 11; LED paster 7 to be installed between the first object lens 10 and the second object lens 11 and to be positioned at the position corresponding to edge of the first object lens 10 rear end.Field angle needed for guarantee and imaging resolution, compare and the scheme being placed on the first object lens 10 front end, can avoid blocking visual field, improves resolution.
As shown in Figure 2, the marginal portion of the first object lens 10 is designed to planoconvex lens, for converging light.The light of LED paster excessive for lighting angle can be converged, thus avoid affecting imaging system, and can brightness of illumination be strengthened.
First object lens front end face is plane, and as the screening glass foremost of hard tube mirror, need not arrange separately front screening glass, cost decreases.
LED paster 7 is white light LEDs paster.Mirror pipe 6 is stainless steel material.
To sum up, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
