Ealing / Beck Microscope Condenser Mount
Call 781-871-8868 for Price
This is a very fine condenser holder which I believe is from the Ealing / Beck Research Optical Bench. It is exquisitely made and all motions are perfectly free of backlash and exceptionally smooth. It includes a pin mounting. One of the two centering screws is missing the milled adjusting head, but it still moves freely. It should be replaced for more efficient use.
The condenser mount accepts sleeve-type condensers of 38.75mm diameter. There is a locking screw for securing the condenser. The condenser may be centered to the optic axis with plus / minus 1.5mm axial motion. The two centering screws are located at right angles to each other so motion is imparted in an orthogonal manner. Once the condenser has been centered, a locking screw coaxial to the spring plunger is used to prevent further drift. The rack and pinion focus drive has an excursion of approximately 20mm..
The pin is 12mm in diameter and 58mm long. Distance from nominal optical center to the pinion base (top of pin) is 45mm. The dovetail for the motion has a cylindrical profile which is very unusual.
