This adapter fits a Bausch and Lomb StereoZoom 7 microscope equipped with a trinocular camera port to a digital SLR camera via an SLR bayonet fitting.
The term kinematic in this context means that the mechanism provides minimal mechanical constraints to locate the components relative to each other.Full engagement to the camera lens typically requires only 2 or 3 careful turns.Many cameras accept up to 8mm for the threaded portion instead of just 4mm, since 4mm is only about 5 threads of a 32 tpi pitch, and at least 2 of these 5 threads must be relieved for runout up to the shoulder in single-point.The adapter and digital camera are shown here mounted on the beamsplitter for the Topcon SL-7E slit lamp.The adapter shown here (25mm focal length) nests entirely within the opmi fitting, as does the camera's turret, leaving only about an inch of the tiny camera projecting out from the beamsplitter.Modifying the Microsoft Lifecam Cinema and Lifecam Studio for Instrumentation Applications At left is an example of how I modify the the Microsoft Lifecam Cinema (720p HD) and Microsoft Lifecam Studio (1080p HD) cameras for scientific and medical instrumentation.Canon includes a basic remote capture application with the camera.The adapter piece is machined from aluminum to be very lightweight yet strong.This adapter mounts an Imaging Source camera on a Questar telescope.An Olympus photo eyepiece for film photography, such as an "NFK.5X LD 125 is designed not to produce an afocal image such as you would view by eye, but instead to relay an image 125mm further up from the registration surface, the image being.See also a high-resolution (3872 x 2592) digital anterior photograph 513KB jpeg file as taken with this instrument and adapter.Thus the adapter will consist of a turret with outside threads to mate to the camera lens, and an inside bore to slip snugly over the microscope eyepiece.The connector receptacle (not shown, see above photos) mounts in the large hole in the bracket, and connects to the mating plug on the cable.This camera provides 1080p HD video via a hdmi or RGB connection from a separate controller.
In terms of typical dimensions, a typical 10X wide-field eyepiece exit pupil is sized as a disk of about 10mm diameter floating about 20mm above the eyepiece, while a typical large camera lens has an entrance pupil 35mm or more in diameter, located 50mm.
See the mechanical drawing 572 KB PDF file, 1 page for details.
An electronic interface circuit contained inside the grey connector hood converts the logic and levels of the film camera signals to be compatible with the digital connections.
This choice of geometry is called the "crop and is fixed by the optical scaling by the adapter of the instrument field onto the digital camera sensor.
The photo at the left shows a typical photo eyepiece ( mechanical drawing 256KB PDF file) which I designed and fabricated to adapt a 58mm camera thread to a 23mm eyepiece tube.
However, see my custom adaptation of the SD750 and SD790 above.Photographic enlarger lenses use several standard threads for mounting.With camera lenses, bigger is usually better, since you can gather more light.This is my custom adapter which replaces the original Olympus fitting with a T-mount camera thread, which is then adapted for use with digital SLR cameras.Since the microscope objective is working maya unlimited 6 crack in reverse, the sampled spot size on the microscopic subject is reduced (minified) by the magnification factor of the objective; for example, a 10X objective would reduce a 100 micron illuminated installing cruise control on manual transmission fiber core diameter to a sampled spot.Depending on the application, this choice may be simply a matter of visual style, or it may be dictated by requirements such as having to see all of the microscope field (which dictates an inscribed crop) or having to use all of the camera field.The adapter afocalizes the end of the fiber, creating a collimated beam of laser light, and inserts this beam into the Olympus microscope imaging path through the reflected path of the Olympus U-DP beamsplitter.She asserts most EF lenses provide 58mm filter threads, with 52mm on some cheaper lenses, 78mm on most professional lenses, and 72mm on some older lenses.Tethering the camera to a PC display is thus desirable with the pivoted orientations.Kowa's instrument design is quite suitable for digital conversion because the viewfinder is a fixed and separate part of the instrument, instead of being incorporated into the 35mm film or Polaroid film camera backs.Photo eyepiece V3 sample image: Bausch Lomb Galen II,.54mm field width at 100X,.9 micron/pixel, showing a thin central section of a woody pine stem.Sometimes the scaling of the circular field may be deliberately shrunk to somewhat smaller than the vertical aspect, to allow for manufacturing tolerances in the optical and mechanical elements.Alan Wood documents the Olympus OM series of film cameras (1972-2003 for which Olympus produced adapters for fitting to Olympus microscopes, at his Olympus OM System Page.Inscribed cropping: The circular microscope field of view "inscribes" the rectangular camera field of view.
