Description

Pocket microscope

The utility model relates to a kind of pocket microscope, belongs to optical instrument field.

Present existing ordinary optical microscope can be divided into two big classes: the first kind is a conventional optical microscope, and it is mainly constructed and is divided into: (1) is separately fixed at the device (3) that optical amplification system (2) that the lens barrel two ends constitute focuses by ocular head and composition lens and takes from right electro-optical device (4) support, objective table etc.This microscope has following defective: (1) volume is big, complex structure, and enlargement factor is fixed, carry very inconvenient (2) and cost an arm and a leg, every needs Renminbi 400-600 unit, and can not popularize use (3) need focalize, select light source, limited by natural conditions, very inconvenient; Second class is to have increased lighting source on the basis of conventional optical microscope, this microscope is limited by natural conditions no longer when using, but still need focus, and fundamentally solution does not have the microscopic structure complexity now, enlargement factor is fixed, used and carry inconvenience, expensive problem, still can not popularize use.

The purpose of this utility model be to provide a kind of simple and reasonable, enlargement factor is adjustable, be easy to carry about with one, (need not to focalize and select light source) easy to use, cheap pocket microscope.

Pocket microscope provided by the utility model, form by the hold down gag of box body (1), bead lens (2), lens holder (3), microslide (5), microslide (5), electric light source etc., electric light source is arranged at the bottom in the box body (1), it is to be formed by connecting by battery (13), miniature bulb (15), switch (9) and lead (14), it is characterized in that: lens holder (3) is one to be inlaid in the boss that box body (1) is gone up on the end face and had through hole, and bead lens (2) are arranged in the through hole; The hold down gag of microslide (5) is formed by having the clamping piece (11) and the compression spring (12) that promote plush copper (6), and the lower end of clamping piece (11) compression spring (12) interior with being fixed on box body (1) connects; The top, one side (8) of box body (1) has the insertion mouth (4) of microslide (5) at interval and promotes the hatchway (7) of plush copper (6).

Pocket microscope according to the utility model regulation, box body (1) is gone up end face and is provided with a dovetail groove, lens holder (3) is a truncated rectangular pyramids, through hole and bead lens (2) in it are interference fit, and the lens holder (3) that bead lens (2) are housed passes dovetail groove and is inlaid on the last end face of box body (1).

Pocket microscope according to the utility model regulation, also be provided with a flap (10) in the box body (1), half sheet plate in the flap (10) and side (8) be arranged in parallel and form a chute, having the clamping piece (11) that promotes plush copper (6) is arranged in the chute, promotion plush copper (6) on the clamping piece (11) is stretched out outer also the floating of box body (1) and is arranged in the hatchway (7), other half sheet plate in the flap (10) connects with the another side of box body (1), and it be positioned at bead lens (2) under locate to be provided with a light hole (18).

Pocket microscope according to the utility model regulation, flap (10) is being provided with a hinged garden shape dimmer board (17) under the half sheet plate of light hole (18), the part plate face of dimmer board (17) stretches out outside the box body (1), dimmer board (17) is provided with large and small different one group of light modulation hole (16), and each light modulation hole (16) all can be on the same straight line optical channel with light hole (18), bead lens (2) by rotating dimmer board (17).

Because the utility model adopts bead lens (2) to replace the optical amplification system of conventional optical microscope, make of the present utility model simple and reasonablely, and manufacturing cost significantly descends.According to the spherical mirror amplification principle, the bead lens can amplify object, and this point is confirmed by experiment, and can obtain such conclusion: " the bead lens diameter is littler, and its enlargement factor is bigger ".Therefore replacing the optical amplification system of conventional optical microscope with the bead lens, is feasible.

Because the utility model is equipped with the lens holder (3) of bead lens (2) and is inlaid on the last end face of box body (1), the diameter difference of the bead lens of being adorned in the lens holder (3) (2), enlargement factor of the present utility model is just different, therefore can have the lens holder (3) of different-diameter bead lens (2) by replacing, and obtain the adjustable pocket microscope of enlargement factor.

Because the utility model has adopted the hold down gag of being made up of clamping piece (11) and compression spring (12), clamping piece (11) can be with microslide (5) jack-up and compressing upwards, can make that like this observing object on the microslide (5) can be near bead lens (2), thereby obtain amplification effect clearly, do need not to focus like this, saved focus control; In addition, be provided with an electric light source in the utility model, can limit by natural conditions so in use, need not to select light source; Also be provided with the dimmer board (17) of a scalable light power in the utility model, can provide suitable illumination intensity to observing object by rotating dimmer board (17), thereby more help obtaining amplification effect clearly.

Because the utility model is combined in above-mentioned these in less box body of volume (1) rational in infrastructurely, thus obtain a kind of simple and reasonable, enlargement factor is adjustable, be easy to carry about with one, the pocket microscope of (need not to focalize and select light source) easy to use.

Because bead lens of the present utility model (2) adopt comparatively simple known processing technology to make with ordinary optical glass, electric light source is formed by connecting with common bulb and dry cell, switch and lead, compression spring (12) is to select universal standard part for use, and box body (1) and other parts adopt plastics to make, so calculate by statistics, integrated cost less than ten yuans of the present utility model, price is quite cheap.
