Abstract

The Japan national large telescope (JNLT) project challenges new technology in adopting an actively supported monolithic 8 m mirror of meniscus form with a thickness of 20 cm. An air- flow-controlled co-rotating telescope enclosure is designed to protect the sensitive main mirror from disturbing wind, yet to keep enough flushing effect, in order to achieve the high image resolution target of approximately 0.'2.
