“…We have applied the IAH to a segmented aperture similar to that used in the Thirty Meter Telescope (TMT; Nelson & Sanders 2008 ;Sch öck et al 2009 ;Cole 2017 ), one of the largest and most technologically advanced telescopes in the world. Scheduled for construction at Mauna Kea, Hawaii, USA, and it is planned that the telescope will MNRAS 523, 5442-5451 (2023) have its first light in the early 2030s, this ground-based astronomical observatory is a collaborative effort among astronomical communities from India, Canada, China, Japan, and the United States, who are jointly determining the scientific goals, array of instruments, and o v erall design of the TMT observ atory (Si v arani et al 2022 ). The observatory boasts a 30-m diameter segmented mirror, comprising 492 hexagonal elements, each with a corner-to-corner measurement of 1.44 m. These segments are meticulously arranged, maintaining a mere 2.5 mm gap between them (Nelson & Sanders 2006 ).…”
