Meade 4 Inch Refractor

The Meade Instruments Corporation (also shortened to Meade) is an American multinationalcompany headquartered in Irvine, California, that manufactures, imports, and distributes telescopes, binoculars, spotting scopes, microscopes, CCD cameras, and telescope accessories for the consumer market.^[2] It is the world's largest manufacturer of telescopes.^[3]

Besides selling under its 'Meade' brand name, the company sells solar telescopes under the brand 'Coronado'. Its products are also imported and sold in Europe by a former subsidiary under the Meade and Coronado brand names.^[4]

Origins and history[edit]

Founded in 1972 by John Diebel, Meade started as a mail order seller of small refracting telescopes and telescope accessories manufactured by the Japan-based Towa Optical Manufacturing Company.^[3] Meade started manufacturing its own line of products in 1976, introducing 6' and 8' reflecting telescopes models in 1977. In 1980, the company ventured into the Schmidt-Cassegrain market that up to that time had been dominated by Celestron Corporation.^[3] Meade has a long history of litigation with other companies over infringement of their patents, particularly with its once bitter rival Celestron. In August 2008, Meade modified their line of Schmidt-Cassegrain telescopes with changes to the optical surfaces in design they call 'Advanced Coma-Free optics' (ACF Optics).^[5]

Past production sites include 16542 Millikan Avenue in Irvine, which was used in the 1990s. Meade production was consequently moved to a new build plant in 6001 Oak Canyon, located as well in Irvine. The Oak Canyon plant was in use for about a decade until 2009, after which production was moved to an expanded plant in Tijuana, Mexico.^[6]^[7]

On November 26, 2019, in the United States District Court for the Northern District of California a federal jury found that Ningbo and Meade suppressed competition and fixed prices for consumer telescopes in the United States in violation of federal antitrust laws (case# 16-06370).^[9] Optronic Technologies, Inc. was awarded $16.8 million in damages.^[10]

On December 4, 2019, Meade Instruments Corp. filed bankruptcy in the United States District Court for the Central District of California as case number 19-14714.^[11]

Catadioptric cassegrains[edit]

ACF telescopes[edit]

ACF (Advanced Coma-Free) is an altered version of the Meade's previous schmidt-cassegrain telescopes that replaces the traditional spherical schmidt-cassegrain secondary mirror with a hyperbolic secondary mirror. In the new design the full aperture corrector is slightly altered in shape and combined with a spherical primary mirror.^[14] Meade's literature originally describe their ACF as a variation on the Ritchey-Chrétien telescope, although it does not use the two hyperbolic mirror combination in that design (being more of an aplantic design).^[15] After a legal settlement Meade dropped the claim.^{[citation needed]}

Models

LX90-ACF, 8' to 12'^[16]
LX200-ACF, a series of LX200 with ACF Optics 8' to 16'^[17]
LX400-ACF, 16 to 20' f/8, w/ robotic equatorial mount^[18]
LX800^[19]

Maksutov telescopes[edit]

The Meade 'ETX' series Maksutov-Cassegrain telescope (105mm aperture).

Meade produces a line of Maksutov telescopes under their ETX series (Everybody's Telescope). They were first produced in 90 mm (3-1/2') Maksutov Cassegrain telescope in 1996. They range in size from 90 mm to 125 mm.

Newtonian telescopes[edit]

GoTo telescopes[edit]

Many Meade telescope lines are classified by the self aiming computerized alt-azimuth and equatorial mounts they come on, a technology commonly called a 'GoTo' mount.

Solar telescopes[edit]

In 2004, Meade acquired Coronado Filters from founder and designer David Lunt,^[20]^[21] who produce an extensive range of specialty telescopes that allow views of the sun in Hydrogen-Alpha, and formerly, at Calcium K line wavelengths. The Meade Coronado telescopes are called 'Solarmax 40' or higher depending on the model.

Other products[edit]

Achromatic refractors (5 and 6-inch)
Meade also sells under the 'Meade' name imported low to moderate cost reflectors and refractors intended for the beginner retail market.

Telescope accessories[edit]

Accessories produced by Meade include the series 5000 eyepieces that are comparable in construction to those of Chester, New York-based Tele Vue Optical's 'Nagler' (82-degree field of view), 'Panoptic' (68-degree field of view), and 'Radian' (60-degree field of view) eyepieces. Meade sells Deep Sky and Lunar digital imagers for telescopes. They also market the mySKY & mySKY Plus, multi-media GPS devices guiding users to the sky, similar to the competing Celestron SkyScout.
