BECK DRAWING APPARATUS.
No. 3660
The method of drawing objects, as seen through the microscope, by means of projecting an image on to the paper, is perhaps the most simple of any method. It requires no artistic skill, and it is simply the outlining of a picture which is actually projected on to the drawing paper.
The difficulty generally arises in obtaining a sufficiently visible picture giving good contrast, and thus making the process of drawing easy and certain. The arrangement of the microscope, lamp, etc., also present some difficulties.
We have, therefore, produced a self-contained apparatus with lamp, a platform for the microscope, right angle prism and drawing board. The apparatus is provided with adjustable curtains which exclude all extraneous light from the drawing board. These curtains are so arranged that they can be folded back, while the adjustments of the microscope are operated and let back in position while the drawing is being carried out. It will be found that with either of the illuminants which we list this apparatus can be used with any powers up to and including a 1 /12th, and that even with the latter power when all light is shut off by means of the curtains, an image is projected which is quite sufficiently brilliant to enable drawings to be made with ease.
In ordering, the pattern of microscope should be specified, also the diameter of the eye end of the draw-tube over which the prism has to fit.
