Instrument Name: Zeiss Photomicroscope
A large laboratory microscope with an integrated, internal 35mm camera. The microscope consists of two main units: the microscope (stage unit), and an external “automatic exposure device.” Two additional film magazines are also present in this example.
The eyepiece extends from the tube head at the top of the unit. Film magazines are mounted inside the camera body from the right side. An electrical photocell measuring light intensity for exposure control is housed inside the body. A lever below the film magazine mount cocks the shutter and operates the film advance. A knob on the opposite side sets the shutter speed. The objective turret holds five objective lenses. This microscope has a complicated substage featuring a transmitted-light condenser. A remarkable amount of wear is evident on the finish of the stage beneath the focus wheels. A built-in illuminator is housed in the base of the stage beneath the stage. The lamp is located at the back of the unit.
The automatic exposure device attaches to the stage unit with two cords (missing from this example). Illumination, exposure, and shutter functions can be controlled from this device.
35mm photographic film is loaded into a spool holder. This fits inside a magazine which is mounted in the body of the camera. This microscope comes with two additional magazines, one of which has film inside.
