Abstract

A test cell useful for determining the photosensitivity of a photopolymerizable material, includes a support plate having a top surface portion, a bottom surface portion, and an opening extending therebetween, a light-transmissive base member removably or permanently connected to said bottom surface portion to form with said opening a well, into which well photopolymerizable material can be deposited, and a sensor comprising a thermal sensor, strain sensor, or combination thereof operatively associated with said light-transmissive base member.
