In this report, we present an optical design for a 3-sided reflective pyramid wavefront sensor which allows for the imaging of the pupils onto a single detector. A general approach for this reflective design is demonstrated; however, in effort to implement the optical system into the Shane Telescope's adaptive optics module, this reflective pyramid wavefront sensor design is constrained by the module's current specifications. Due to the physical constraints in the AO module, the developed optical design shares an undeviated optical axis with a transmissive wedge solution for discrete modulation. Pupil images were created using a lab test bench that demonstrates the design's proof of concept. We will discuss the details of the optical design and its motivating parameters using the Shane Telescope's adaptive optics module.
