Bausch & Lomb Optical Company The apparatus also furnishes an excellent light source for photomicrography, and any laboratory having occasion to use a simple illuminating apparatus will find numerous uses for it. Figure 3—Simplified Micro-Projection Apparatus without Optical Bed, Showing Regular Table Microscope Clamped to Baseboard. In order to provide as inexpensive an outfit as possible we are prepared to supply this apparatus with a bi-convex condenser of spherical curvature in place of the aspheric condenser and also without the optical bed. (See Figure 3.) This condenser does not, of course, give the clear, brilliant field obtained with the aspheric, but its efficiency is of a comparatively high order. When the optical bed is omitted, a simple clamp is provided at the end of the baseboard to hold the microscope. 85
