ETX may refer to:
A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics). Catadioptric combinations are used in focusing systems such as searchlights, headlamps, early lighthouse focusing systems, optical telescopes, microscopes, and telephoto lenses. Other optical systems that use lenses and mirrors are also referred to as "catadioptric", such as surveillance catadioptric sensors.
Mài is a Chinese surname. It is commonly transliterated as Mak in Hong Kong, based on the Cantonese pronunciation, though other transliterations exist. "麥" is the standard character in both Traditional and Simplified scripts but 麦 is also a variant seen in both. The meaning of the Chinese character is either wheat or barley. According to a 2013 study, 麦 was the 200th most common surname, shared by 550,000 people or 0.041% of China's population, with Guangdong being the province with the most.
The Maksutov is a catadioptric telescope design that combines a spherical mirror with a weakly negative meniscus lens in a design that takes advantage of all the surfaces being nearly "spherically symmetrical". The negative lens is usually full diameter and placed at the entrance pupil of the telescope. The design corrects the problems of off-axis aberrations such as coma found in reflecting telescopes while also correcting chromatic aberration. It was patented in 1941 by Soviet optician Dmitri Dmitrievich Maksutov. Maksutov based his design on the idea behind the Schmidt camera of using the spherical errors of a negative lens to correct the opposite errors in a spherical primary mirror. The design is most commonly seen in a Cassegrain variation, with an integrated secondary, that can use all-spherical elements, thereby simplifying fabrication. Maksutov telescopes have been sold on the amateur market since the 1950s.

John or Johnny Gregory may refer to:
Albert A. Bouwers (1893–1972) was a Dutch optical engineer. He is known for developing and working with X-rays and various optical technologies as a high-level researcher at Philips research labs. He is lesser known for patenting in 1941 a catadioptric meniscus telescope design similar to but slightly predating the Maksutov telescope.
John F. Gregory was an American optical engineer and a popularizer of amateur telescope making. He is credited with the design of a version of the Maksutov telescope called the "Gregory-Maksutov telescope".
The MAK – Museum of Applied Arts is an arts and crafts museum located at Stubenring 5 in Vienna's 1st district Innere Stadt. Besides its traditional orientation towards arts and crafts and design, the museum especially focuses on architecture and contemporary art. The museum has been at its current location since 1871. Since 2004 the building is illuminated in the evenings by the permanent outdoor installation "MAKlite" of American artist James Turrell. In 2015 the MAK became the first museum to use bitcoin to acquire art, when it purchased the screensaver "Event listeners" of van den Dorpel. With over 300,000 objects displayed online, the MAK presents the largest online collection within the Austrian Federal Museums. The audio guide to this museum is provided as a web-based app.
