. Beck microscopes. Microscopes. The Luminex magnifier is the latest development in magnifiers, the source of light for the illumination of the object being contained in the instrument. By means of a specially shaped reflector the light is condensed into a brilliant patch which shows detail in the most effective manner. The convenience of this method is readily seen, as however inaccessible the object may be, or in whatever position the magnifier is held, an intense light is thrown upon the object. The Luminex is made in a fixed focus model, focussing the object just below the rim of the reflector. This has a power of x 10. Another model, made with a power of either X 10, X 15 or x20, has a focussing motion to the lens, so that the magnifier may be rested upon an object and the image brought into focus by the adjustment to the lens. The power x 20 is fitted with an achromatic lens, giving at this high magnifying power a field of view free from aberration. A model containing a graduated scale which is seen superimposed upon the object being viewed, so that measurements can be readily taken, is also manufactured ; this has a power of X 10. A focussing adjustment is provided to the lens, bringing both scale and object into accurate focus. Anv of the following scales can be supplied :— I in. straight scale divided into lOths, 50ths and 200ths of an inch, =-\ 10 m/m. straight scale divided into 100 divisions, , 1/lOth of a millimetre. Squares over the whole field in either J, I or 1 m/m*.
