Description
Technical field
The utility model relates to microscopic structure to be improved, and is specifically related to a kind of zoom-stereo microscope based on LED cold light source coaxial-illuminating device, may be used for observation and the detection of deep hole class sample, belong to microscopy field.
Background technology
Zoom-stereo microscope has a wide range of applications in fields such as education, industry, medical treatment, business qualifications.Wherein in industrial detection, for deep hole of workpiece or heavy parts degree of depth crack, then need the stereomicroscope with coaxial-illuminating light source, what ability was good realizes object.Common zoom-stereo microscope adopts skew ray indirect illumination or circular lamp illumination, all can not be close to imaging system and arrive detection position, helpless to the detection of the hole or crack that reach certain depth.In line illumination systems design, lighting source is that outgoing arrives detecting position and puts from imaging eyepiece, is for coaxially.
What coaxial-illuminating design in the past adopted is halogen light source, because stereomicroscope is double light path imaging, so halogen light source 360 degree of luminescences, is convenient to illuminator and collects light source from Halogen lamp LED both sides, enter two-way imaging system.
Halogen light source coaxial-illuminating zoom-stereo microscope is generally made up of zoom main body and frame, and coaxial-illuminating device is positioned at position, main body back upper place, built-in light source.The anti-heat of halogen light source is large, and the radiating groove at its top can not provide enough radiating conditions.This situation is very disadvantageous for needs long observation operation.Fig. 1 adopts Halogen lamp LED to be that (hollow arrow is illuminating ray direction for the coaxial-illuminating zoom-stereo microscope systematic schematic diagram of light source, filled arrows is imaging radiation direction), as we can see from the figure, Halogen lamp LED coaxial-illuminating device adopts a Halogen lamp LED 9 for light source, enter two illumination paths respectively, then enter two object lens light paths realization illuminations respectively.Halogen lamp LED 9 two-way light path, before entering semi-transparent spectroscope 2, needs two groups of catoptrons 10 to change optical path direction.As can be seen from Figure 1, due to position relationship, moulding light path is longer, and light path has carried out multiple reflections, and focusing position is many and complicated, needs two light paths to return unit on a Halogen lamp LED.
Because the energy utilization rate of Halogen lamp LED is low, thermal value is very high again, and the high temperature that the luminaire like this in imaged body inside produces all passes to whole main body, very unfavorable to microscopical use operation.To such an extent as to this product is in very awkward condition in visual field always, most users has to because temperature is too high abandon.
Halogen lamp LED coaxial light source is due to structure arrangement problem simultaneously, also makes main part be difficult to arrange photography three order structure, does not often install the interface of digital equipment.
Summary of the invention
For prior art above shortcomings, the purpose of this utility model is to provide a kind of zoom-stereo microscope based on LED cold light source coaxial-illuminating device, the utility model effectively can eliminate the heating problem that original halogen light source causes, digital equipment can easily be installed, to export electronic image simultaneously.
To achieve these goals, the technical solution adopted in the utility model is such:
Based on the zoom-stereo microscope of LED cold light source coaxial-illuminating device, comprise coaxial-illuminating device, two semi-transparent spectroscopes, the continuous zoom body be made up of two continuous zoom object lens and two eyepieces, two semi-transparent spectroscopes, two continuous zoom object lens and two eyepieces are corresponding formation two independently imaging optical path respectively.Described coaxial-illuminating device be two covers that structure is identical and with two semi-transparent spectroscope one_to_one corresponding, often overlap coaxial-illuminating device and form by LED cold light source with to the condensing member of LED cold light source optically focused, semi-transparent spectroscope and condensing member emergent light are 45 ° and arrange; Two coaxial-illuminating devices, two semi-transparent spectroscopes and two continuous zoom object lens are corresponding formation two independently illumination path respectively.
Two imaging optical paths are arranged symmetrically with, the side that two cover coaxial-illuminating devices are positioned at the relative two imaging optical path symcenter of respective imaging optical path to.
Turn to prism often overlapping imaging optical path is provided with, turn to prism between semi-transparent spectroscope and eyepiece.
Described condensing member is made up of condenser and lens, and condenser is between lens and LED cold light source, and lens are between semi-transparent spectroscope and condenser.
The utility model, by adjustment optical lighting system, reasonably achieves the application of LED light source on zoom-stereo microscope.Compared to existing technology, the utility model has following beneficial effect:
1, the relative halogen light source of LED light source compares, and has the features such as cost is low, electric energy conversion efficiency is high, thermal value is little.
2, the application of LED light source also relative simplicity original structure, namely original coaxial-illuminating light source is cancelled because the radiator structure of the large needs of thermal value, therefore while optimizing structure, reduce manufacturing cost and difficulty, and then make axis light illuminator obtain better effect in application aspect.
3, two LED coaxial-illuminating device positions use flexibly, can easily install digital equipment, export electronic image.
