Morphology
off-axis + reflector
The phrase is directly compositional: 'off-axis' means away from the central axis (i.e., not on the axis) and 'reflector' denotes a mirror-based telescope, so together they describe a reflector positioned or tilted off the optical axis. This follows ordinary noun-modifier composition and is inferable from the constituent meanings, so learners who know the parts can deduce the overall sense.
Etymology
Off-axis reflector is a type of reflector telescope where the main mirror is tilted so light is sent to the side instead of along the center. Because the light goes 'off-axis' or 'to the side', nothing in the middle blocks it, so the design gives a clearer image and lets a viewer use a side eyepiece.
