Abstract
The utility model relates to a new viewing lens unit for a continuous zoom type stereomicroscope including two objective lenses (1), a half-angle prism (2), an erecting prism (3) and two eyepieces (4). The utility is characterized in that a photographic object (5), a primary reflector (6) mounted above the photographic object (5), a secondary reflector (7), a photo ocular (8) and a photographic equipment (9) which are arranged in the reflective direction of the secondary reflector (7) are also included. The optic axes of the two objective lenses (1) and the photographic object (5) have an intersection point, the photographic object gear (11) on the body tube of the photographic object (5) individually engages the two objective lenses gears (10) on the body tubes of the two objective lenses (1), the spiral neck grooves (13) (12) on the body tubes of the photographic object (5) and the two objective lenses (1) have reverse directions, the photo ocular (8) and the two eyepieces (4) are triangle arranged. The continuous zoom stereomicroscope viewing lens unit does not affect the stereoviewing effect of the original object lens, at the same realizes the function of taking photographs.
Description
One, technical field
The utility model relates to a kind of continuous zoom viewing head that is used on the stereomicroscope, the particularly a kind of continuous zoom stereomicroscope observation head that can make a video recording.
Two, background technology
The viewing head of existing stereomicroscope has two-way to observe lens barrel, has following manner to realize in the time of photographing usually:
1. the on the left side prism is observed on the lens barrel and is removed half pentagonal prism, makes to go to the photo ocular tube behind imaging beam two secondary reflections of left side object lens and realize camera function through camera mechanism again.At this moment, can only use the right object lens to observe object, no stereoscopic result.
2. on two and half pentagonal prisms of prism viewing head, respectively glue together a prism that is coated with semi-transparent semi-reflecting film, respectively tell a light path.On these two new light paths, one causes camera, and one causes lighting device, realizes camera function and indirect illumination function respectively.Owing to used semi-transparent semi-reflecting film, the brightness of image and contrast all obviously descend, and have influenced the observing effect of binocular.
Because existing continuous zoom stereomicroscope observation head all need reduce reality under the prerequisite of observing quality when photographing, so bring inconvenience for observation work.
Three, summary of the invention
The utility model purpose is to provide a kind of continuous zoom stereomicroscope observation head that the binocular observation effect can be realized camera function simultaneously again that neither influences.
New type of continuous of the present utility model becomes a times stereomicroscope observation head and comprises two viewing objectives, the half-angle prism, erecting prism, two observation eyepieces, it is characterized in that it also comprises a photographic field lens, be positioned at a reflective mirror of photographic field lens lens barrel top, the secondary reflecting mirror, be positioned at photo ocular and camera on the secondary reflecting specular reflection direction, the optical axis intersection of two viewing objectives and imaging lens is in a bit, on the photographic field lens lens barrel photographic field lens gear respectively with two viewing objective lens barrels on the viewing objective gearing mesh, photographic field lens helix groove on the photographic field lens lens barrel is opposite with viewing objective helix groove direction on two viewing objective lens barrels, and camera and two observation eyepieces are isosceles triangle and distribute.
Because continuous zoom stereomicroscope observation head of the present utility model has increased a photographic field lens, thereby increased a light path, this light path aims at the realization camera function and increases, the multiple of the photographic field lens that increases newly and two viewing objectives are identical, photographic field lens helix groove opposite with viewing objective helix groove direction, under two viewing objective gear drivens, the photographic field lens gear also rotates, realize the purpose of the image synchronization of three object lens, therefore, do not influence original binocular observation effect at all.
Four, description of drawings
Fig. 1 is the structural representation of the utility model continuous zoom stereomicroscope observation head;
Fig. 2 is the structural representation of the utility model continuous zoom stereomicroscope observation head mirror tube part;
Fig. 3 is the vertical view of the utility model continuous zoom stereomicroscope observation head gear parts.
Five, embodiment
Be described further below in conjunction with the structure of accompanying drawing the utility model continuous zoom stereomicroscope observation head:
The utility model continuous zoom stereomicroscope observation head has comprised the basic structure of common continuous zoom stereomicroscope observation head, two viewing objectives 1 are promptly arranged, half-angle prism 2, erecting prism 3, two observation eyepieces 4, viewing objective gear 10 and driven wheel 14 engagements are arranged on two viewing objective 1 lens barrels, adjust the viewing objective helix groove 12 of viewing objective 1 multiple on two viewing objective 1 lens barrels in addition, the characteristics of the utility model continuous zoom stereomicroscope observation head are that it has also increased a photographic field lens 5, the optical axis of the optical axis of photographic field lens 5 and two viewing objectives 1 meets at a bit, a photographic field lens gear 11 is arranged on photographic field lens 5 lens barrels, mesh respectively with two viewing objective gears 10, on photographic field lens 5 lens barrels, also have one identical with viewing objective helix groove 12 structures, the photographic field lens helix groove 13 that direction is opposite, photographic field lens 5 lens barrels top is provided with a reflective mirror 6, above reflective mirror 6, also has a secondary reflecting mirror 7 on the direction parallel with reflective mirror 6, photo ocular 8 and camera 9 are set on the reflection direction of secondary reflecting mirror 7, photo ocular 8 and two observation eyepieces 4 are isosceles triangle and distribute, the multiple of the multiple of photographic field lens 5 and two viewing objectives 1 is identical, and the multiple of the multiple of photo ocular 8 and two observation eyepieces 4 is identical.
When the utility model continuous zoom stereomicroscope observation head is observed under the driving of using at driving wheel, regulate transhipment driven wheel 14, thereby driving two viewing objective gears 10 rotates, two viewing objectives 1 enlargement factor at this moment changes synchronously, photographic field lens gear 11 backward rotation under two viewing objective gears 10 drive, because the direction of photographic field lens helix groove 13 is opposite with viewing objective helix groove 12, therefore the enlargement factor of photographic field lens 5 changes identically at this moment, the image that produces arrives photo ocular 8 and cameras 9 through reflective mirror 6 and 7 reflections of secondary reflecting mirror, thereby reach the photography purpose, also do not influence binocular observation simultaneously.
