R. & J. Beck MICROSCOPE

Brass microscope signed on the tripod R.&J. Beck.

Broad, heavy tripod base.  From the centre of the base rises a stout column, to the top of which is attached, by a firm joint, the Jackson model arm, carrying the compound body, by which the inclination can be varied to any degree, from vertical to horizontal. Beneath the stage is a tube carrying all the sub-stage apparatus, the achromatic condenser, a double mirror concave and plane is hung upon a swinging bar, and with every possible motion for direct and oblique illumination. The stage is of glass, with a complete rotation in the optic axis, upon the top of which is a sliding object- holder, very thin, and with a spring clip for holding the object in place during rotation. This clip is removable. Focus adjustment by means of rack and pinion, with large milled heads.
