- Description:
- In this apparatus, the whole condensing system is arranged to slide upon one rectangular bar firmly attached to a base-board. There being no continuous base-board, the camera is kept in line with the condensing system by means of two telescopic tubes attached to the sides of the base of the condensing system. It is claimed for this system that a more perfectly corrected and powerful illumination is secured, in the following way:- The light from the zirconium jet is taken up and parallelised by the doublet condenser, and from thence falling upon the lens, is converted into a converging cone which, entering another lens, is again parallelised, the emergent beam being of such size as exactly to fill the back lens of the sub-stage condenser. A water - tank is interposed to take up the heat rays
