Taking photographs with a microscope is relatively straight forward, and most SLR
35 mm film and digital cameras are suitable -
Adapters -
The primary requirements are that the lens system of the camera should be removable and that the camera back has through the lens light metering. Most of the microscopes described in our brochures are suitable and photography adapters can be attached to either the monocular, binocular or trinocular eyetubes of our range of stereo and compound microscopes. Some models do require a slightly more complex adapter and the appropriate accessories are listed for each microscope.
The adapters themselves need to be converted with a T2 ring to the lens fitment of the camera make to be used (Olympus, Canon, Nikon etc.). The microscope in effect becomes the lens system of the camera back, and focus is achieved by looking through the viewfinder of the camera and adjusting the controls of the microscope. The camera back will automatically select the correct shutter speed.
Photoeyepieces -
The adapters need to use an eyepiece in order to achieve the overall magnification that you see by looking down the microscope. An ordinary eyepiece can give acceptable results. However, the specialist photoeyepieces give flatter images if a more professional result is required. If is often worth trying the standard eyepiece supplied with the microscope first before deciding whether or not you consider a photoeyepiece to be necessary.
It should be remembered that 35 mm SLR cameras have freshnel viewing screens best
suited to conventional photography. In some cases they can be heavily frosted (particularly
Nikon and Olympus), this can make focusing the microscope difficult. However in some
models the frosted screens can be replaced with clear screens by your local camera
dealer. Alternatively the parallax periscope focusing device by-
Trinocular microscopes such as the Brunel SP100 (compound) and IMXZ (stereo) have a third eyetube so that the camera back or CCTV camera can be mounted and the microscope used at the same time. In addition these models can be fitted with a parallax focusing system with a periscope focusing device, so that the view finder of the camera does not have to be used for focusing. This adapter is shown attached to a compound microscope trinocular tube and is highly recommended for trouble free focusing for all trinocular instruments.
Parallax focusing device -
Some trinocular microscopes (e.g. Leitz and Olympus) have very wide trinocular tubes
that will only take the manufacturers adapters which can be very expensive. Brunel
Microscopes have special adapters for most of these types of trinocular heads to
reduce them to standard eyetube diameter so that they can then take the adapters
described here. Non SLR digital cameras cannot be attached to microscopes in this
way because the lens cannot be removed -
