Diagnostic Instruments 0.55x Microscope Relay

Description

This is a special relay lens assembly designed for adapting CCD video cameras to various microscope phototubes ports. This particular system consists of four separate elements. The main portion is the relay lens housing itself, which has a tube factor of 0.55x. This allows the camera to encompass a significantly larger portion of the field of view as seen in the binocular tube than would be possible when not using any relay lens. The upper portion is threaded to accept interchangeable camera mounts. Included is a two-part adapter for Sony bayonet mount cameras (ENG 12). This adapter has a locking sleeve which may be used to parfocalize the camera CCD plane to the image in the binocular tube.

The lower portion of the relay adapter tube accepts a series of different clamp tubes used to fit the relay lens to the various microscope phototubes. The included clamp tube is not identified by type letters, but its dimensions are as follows. I believe it is a type BMX suitable for Olympus BX series phototubes.

Length (not including bottom annular dovetail) � 127mm
Dovetail diameter � 42mm
Dovetail height � 5.8mm
Overall diameter of clamp tube base � 59.75mm

The relay system is in excellent condition.
