We report a near-common-path self-reference quantitative phase microscope, wherein a quantitative phase image is formed through the off-axis interference of the sample wave with a 180-degree rotated version of itself. A pair of dove prisms, oriented in different directions, is used to effect the relative transformation between the beams. Our technique features a simple optical design that requires no maintenance, rendering it accessible to nonspecialists in the field of optics. Additionally, its variable magnification and low-noise phase measurement capabilities make it suitable for high-accuracy imaging of biological samples of different sizes.
