The history of the telescope can be traced to before the invention of the earliest known telescope, which appeared in 1608 in the Netherlands, when a patent was submitted by Hans Lippershey, an eyeglass maker. Although Lippershey did not receive his patent, news of the invention soon spread across Europe. The design of these early refracting telescopes consisted of a convex objective lens and a concave eyepiece. Galileo improved on this design the following year and applied it to astronomy. In 1611, Johannes Kepler described how a far more useful telescope could be made with a convex objective lens and a convex eyepiece lens. By 1655, astronomers such as Christiaan Huygens were building powerful but unwieldy Keplerian telescopes with compound eyepieces.
The Newtonian telescope, also called the Newtonian reflector or just a Newtonian, is a type of reflecting telescope invented by the English scientist Sir Isaac Newton, using a concave primary mirror and a flat diagonal secondary mirror. Newton's first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope. The Newtonian telescope's simple design has made it very popular with amateur telescope makers.
Aden B. Meinel was an American astronomer. He retired in 1993 as a distinguished scientist at the Jet Propulsion Laboratory. He also held the rank of professor emeritus at the University of Arizona College of Optical Sciences. His research interests have included upper atmospheric physics, glass technology, optical design, instrumentation and space systems.
The Hale Telescope is a 200-inch (5.1 m), f/3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale. With funding from the Rockefeller Foundation in 1928, he orchestrated the planning, design, and construction of the observatory, but with the project ending up taking 20 years he did not live to see its commissioning. The Hale was groundbreaking for its time, with double the diameter of the second-largest telescope, and pioneered many new technologies in telescope mount design and in the design and fabrication of its large aluminum coated "honeycomb" low thermal expansion Pyrex mirror. It was completed in 1949 and is still in active use.
The Large Millimeter Telescope (LMT), officially the Large Millimeter Telescope Alfonso Serrano, is the world's largest single-aperture telescope in its frequency range, built for observing radio waves in the wave lengths from approximately 0.85 to 4 mm. It has an active surface with a diameter of 50 metres (160 ft) and 1,960 square metres (21,100 sq ft) of collecting area.

The history of Mars observation is about the recorded history of observation of the planet Mars. Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. Chinese records about the motions of Mars appeared before the founding of the Zhou dynasty. Detailed observations of the position of Mars were made by Babylonian astronomers who developed arithmetic techniques to predict the future position of the planet. The ancient Greek philosophers and Hellenistic astronomers developed a geocentric model to explain the planet's motions. Measurements of Mars' angular diameter can be found in ancient Greek and Indian texts. In the 16th century, Nicolaus Copernicus proposed a heliocentric model for the Solar System in which the planets follow circular orbits about the Sun. This was revised by Johannes Kepler, yielding an elliptic orbit for Mars that more accurately fitted the observational data.
The Max Born Award is given by Optica for "outstanding contributions to physical optics" and is named after Max Born.
James Clair Wyant was a professor at the College of Optical Sciences at the University of Arizona where he was Director (1999–2005) and Dean (2005–2012). He received a B.S. in physics from Case Western Reserve University and M.S. and Ph.D. in optics from the Institute of Optics at the University of Rochester.
Charles Sheldon Hastings was an American physicist known for his work in optics. His father was Panet Marshall Hastings and his mother was Jane Sheldon Hastings. The father was a physician and anatomy teacher at Hamilton College, where Charles was born. At the age of six the family moved to Hartford, Connecticut, where Charles received his early education. Hastings entered Yale University's Sheffield School of Science in 1867 and received his bachelor's degree in 1870. His early interest in astronomy and telescopes were likely due to Chester Lyman, Chair of Physics and Astronomy at the Sheffield School. He then earned a PhD from Yale in 1873, and immediately was made an instructor in physics. In 1875 he resigned to study in Germany and France until being named an associate at the new Johns Hopkins University in 1876. He became an associate professor of physics at Johns Hopkins University and the first Chair of Professor of Physics of Sheffield Scientific School at Yale University. He collaborated with John A. Brashear on the optical design of large telescopes including the 72-inch (180 cm) reflector at Dominion Astrophysical Observatory and the 30-inch (76 cm) photographic refractor at Allegheny Observatory. His optical designs enabled much progress in astronomy at U.S. observatories. The Hastings Triplet magnifying glass design is based on his optical formulae. He was awarded the Elliott Cresson Medal in 1926.
