1 INSTRUMENT DESCRIPTION
1.1 Name and Intended Application
The use of commercially available 35 mm SLR cameras on microscopes from Carl Zeiss is a low-price
alternative to photo documentation using the MC 80
DX
and MC 200
CHIP
microscope cameras.
1.2 Instrument Description and Main Features
With the relevant adapters, commercially available 35 mm SLR cameras can be connected to all
microscopes from Carl Zeiss for image documentation in the 24
×
36 mm format.
These adapters feature the magnification factor 2.5
×
, i.e. the image section covered by the 35 mm
format corresponds to a 17.5 mm field diameter in the eyepiece intermediate image.
The instrument-side connection surfaces of the adapters correspond to the camera ports of the
microscopes and phototubes from Carl Zeiss, while the T2 adapter is available on the camera side.
The T2 adapter is standardized: M 42
×
0.75 thread
distance between T2 contact surface and film plane = 54.9 mm
SLR cameras are screwed on the T2 connector via the T2 adapter suitable for the relevant camera. The
T2 adapters are tailored to the flange focal distance (distance between lens contact surface and film
plane) and the lens connector (e.g. Contax or F bayonet) of the camera. This ensures that the film plane
of the SLR cameras always lies in the image plane of the microscope adapters.
Depending on the performance parameters, exposure control is performed by the SLR camera through
TTL metering. Major importance has been attached to automatic exposure control, but manual metering
is also possible.
