  We present a continuous-wave, post selection-free implementation of a
widefield optical multipass microscope. It can be operated with a spatially and
temporally incoherent light source, and requires no active outcoupling or
exotic detection schemes. This implementation is capable of deterministically
interrogating a sample sequentially up to $m=4$ times. Through multiple
interrogations, a linear enhancement in phase shift and absorption imparted by
the sample can be achieved, fundamentally increasing the signal-to-noise of the
obtainable images.
