Abstract
Mt. Abu Faint Object Spectrograph and Camera-Pathfinder (MFOSC-P) is an instrument currently under development for PRL 1.2m Optical-Near Infrared Telescope at Mt. Abu. It is a pathfinder instrument for a bigger and more complex next generation instrument on upcoming PRL 2.5m telescope. MFOSC-P has been conceptualized as a general purpose user’s instrument with sufficient ease in its operation. It offers options for both the imaging as well spectroscopy within the same optical chain in visible waveband (4500-8500 angstroms). The optics has been designed to provide ‘seeing limited imaging’ in astronomy standard Bessell’s B, V, R and I filters. Three modes of spectroscopy with resolutions (λ/Δλ) 2000, 1000 and 500 around 6500, 5500 and 6000 angstroms are achieved with plane reflection gratings. The mechanical system of the instrument has been designed and successfully evaluated for its structural integrity using finite element analysis. Here we present the optical and opto-mechanical designs of the instrument, which have been successfully developed in house under several existing technical constraints. The results of finite element analysis of the instrument are also presented.
