Abstract
In certain embodiments, a beamsplitter includes a substrate and an interior plane within the substrate. The substrate comprises a transparent material and surfaces that receive light from a sample and an overlay projector and transmit light towards oculars and a camera. The interior plane includes a central partially reflective portion and an outer transmissive portion. The central partially reflective portion: transmits a portion of light to direct light from the sample towards the oculars; reflects a remaining portion of light to direct light from the sample towards the camera; and reflects light to direct light from the overlay projector towards the oculars. The outer transmissive portion: transmits light to direct light from the sample towards the oculars; and transmits light to direct light from the overlay projector towards an aperture that blocks the light.
