This meter is closely related to the Chromophot and uses a phosphorescent reference surface. The meter is placed on the viewing lens, the finder then shows a luminous area and a number of small circles, the circle just a little brighter than the background indicates a value which is used in a table to find the exposure setting. The meter was priced at 19/6 for cameras with an f4.5 or f6.3 lens, an adapter was available for f7.7 lenses.
