Abstract: An epifluorescence microscope achieves a compact form factor without sacrificing optical sensitivity by the novel use of combined optic mounts and light baffles constructed using additive manufacturing processes. The use of additive manufacturing enables stray-light-capturing structures that are not practical to make by other techniques. Some embodiments of the present invention do not require installation of filters by an operator, reducing the likelihood of dust and contamination on optical surfaces. Some embodiments of the present invention employ a novel light path that avoids passing the fluorescent light through off-axis elements. This optical arrangement provides for the use of a microscope objective having a finite corrected-image distance, such as a DIN objective, rather than infinity-corrected objective that require additional optical elements to form an image.
