Abstract:
The calibration of the 60-inch aluminization chamber is a critical prerequisite for the successful re-aluminization
of the 1-meter Carl Zeiss reflector telescope mirror. This process ensures the deposition of a uniform and
precisely controlled aluminum coating, which is essential for optimal optical performance. Calibration involves
several key steps, including thorough cleaning and inspection of the chamber, accurate placement and testing
of filaments, and the verification of coating thickness and reflectivity uniformity across the chamber. A series
of test runs culminating in mirror coupons is carried out to confirm these parameters before proceeding with
the final aluminization of the 1-m Carl Zeiss telescope primary mirror at Vainu Bappu Observatory in India.
The entire process is designed to meet the stringent optical standards required for high-precision astronomical
observations.
