Abstract
A simplified version of variable phase contrast microscopy of the polanret type is developed, It uses only a single polarizing ring instead of three zonal polarizers, as required in Osterberg's original polanret device. The polarizing ring is preceded (or followed) by a quarterwave plate and sandwiched between two rotatable polars (polarizer and analyzer).
