No. 3340

The camera has an extension of 30 in. It consists of a steel hexagonal bar supported on four levelling screws. Along this bar slide three frames with connecting bellows, each frame being provided with a clamp screw. The frame at one end holds the ground glass and double plate holder, the frame at the other end carries a flexible bag to attach to the microscope. By means of the levelling screws, the centres of the camera can be adjusted at any height from 5f in. to 71 in.

This camera is in the main features similar to the No. 3340. It, however, has a total extension of 36 ins. and is provided with a reversing back and exposing shutter. An extra front panel is also provided to which can be attached a short focus lens when it is desired to take low power photomicrographs. Four sockets are supplied to screw on to bench, into which the levelling screws fit.

MICROSTIGMAR LENSES.

This series of lenses have been specially designed and corrected for photomicrography. They are found extremely useful when it is desired to take photographs of large objects at low magnifications. The working aperture is f/4’5, and the mounts have the standard R.M.S. gauge of screw.

up the outer tube,

This consists of a high-power lens mounted in an adjustable tube, which can be set so that when it is stood upon the ground glass the latter is sharply focussed. A small portion in the centre of the ground glass screen of our cameras is left clear so that the image can be viewed with the focussing glass without being partially obscured by the ground glass.

The method of setting the focussing glass is as follows: Loosen the top cell which holds the lens combination by slightly unscrewing it, then screw the outer one of the tubes downwards away from the cell, leaving the screw of the top cell exposed. Now hold the inner tube and screw the top cell backwards and forwards until a pencil mark on the lower side of the ground glass is sharply defined, while the focussing glass is held against the upper side. Then screw which will form a lock nut and fix the top cell in the correct position.
