5. Viewfinder focus and shooting
(1) diopter adjustment
In the side view within the eyepiece viewfinder has a glass screen, on which are engraved double cross lines. Adjustment when turning left and right diopter adjustment ring, so that side-view eyepiece viewfinder telescopic tube of the front-end and change the focal length, to clearly distinguish between pairs of cross-line only (see right). Pairs of cross-line calibration, you can not arbitrarily change in diopter adjustment ring, to prevent the focal length change. Viewfinder focus, simply using a microscope focusing screw. Sigma Pharmaceutical Group
In the micro-photography research purposes according to shooting, shooting and shooting is to determine the scope and meaning of images in the film on the object size (multiples). Special microscopic photographic equipment,engraved double cross the line side-view eyepiece viewfinder glass screen on which are engraved there are several kinds of specifications of rectangular viewfinder. Under the scope of photo negatives can not see the entire field of vision, only a circular field of vision in the rectangular section (see right).
viewfinder when the object to make photo images was a rectangular viewing box is located diagonal center, and make the corresponding length of the two. Need to 90 ° adjustment, rotating loading platform or the camera device, so that images of the long axis and horizontal axis parallel to the frame. Image the size of the objective lens and the eyepiece can be used to control the exchange.

(3) Focus and shoot
microscope, the thickness of the focusing spiral rotation, changing lens, and was seized objects in the distance, so that images of objects in the focus of vision gather in the black box of the focal plane.
vertical and horizontal movement Dresser producer samples to find images of filming; the upper and lower rotating focusing spiral, clarify the fine structure of specimens. Viewfinder focus, be repeated several times. Film image clarity determined by a quasi-before shooting the final focus.
viewfinder focusing is completed, immediately pushed the shutter button, any operation must be completed before the focus. After the quasi-coke tiny vibration will give rise to changes in focus, leading to shoot the film image blurred.
6. Record medical R&D
The micro-photography to record the results of scientific research in a way, so microscopic photography, each shot should be one or a number of detailed records of each film has been shooting the film shooting conditions and circumstances, such as being proactive specimen characteristics, instrument portfolio, photos, conditions, exposure time, film type, etc. for subsequent reference work.
