Abstract

MOPTOP is a new polarimeter design for the Liverpool Telescope, which aims to provide a wide field of view with high temporal resolution and multi-colour capability using a combination of a half wave plate, a polarizing beamsplitter and multiple sCMOS cameras. Here we present the optical design of a single-band prototype. We use a combination of commercial achromat and photographic camera lenses to obtain an image quality (100% encircled energy) of < 1.5 arcsec across a 7x7 arcmin field of view and a wavelength range of 400-800nm.
