Description

This is Beck’s ‘New Model Star Microscope’ which was introduced in 1885, this is the later model which was introduced around 1890. It was one of Beck’s cheaper microscopes, the price was between 3 and 5 pounds, depending upon the optics included. This stand is derived from the more elaborate ‘popular microscope’ which could be folded. The microscope has a triangular brass foot plate with a curved  triangular stand carrying the limb between trunnions. The steel limb can swivel over an angle of 90 degrees. The microscope has a square stage with spring clips, below the stage an iris stop or a condenser. The mirror in a bracket is on a swing arm, allowing oblique illumination. With its eyepiece and objective lenses. The instrument has been lacquered ‘arsenic grey’.
