What does Carl Zeiss mean?

Carl Zeiss AG (Carl Zeiss) is a long-established German company that manufactures optical systems, industrial measuring instruments, and medical devices. The company takes its name from one of its founders, the German optician Carl Zeiss (1816-1888). Carl Zeiss began manufacturing scientific instruments in the southwestern German city of Jena, and its commercial activities began in earnest after 1866. A researcher at the time, Dr. Ernst Abbe, developed a theory of microscopic imaging that became the scientific foundation of the optical industry. Dr. Paul Rudolph, one of Abbe's assistants, developed a set of high-performance photographic lenses. As a result of these achievements, Carl Zeiss became the leading company in the field of optical instruments. Since then, along with highly achromatic lenses (1880s), aspherical mirrors (1930s), astronomical telescopes, binoculars, eyeglasses, surgical microscopes, the projector planetarium (1925), and other groundbreaking achievements, Carl Zeiss has been able to remain at the forefront of the optical instrument industry. Carl Zeiss was granted a patent in 1935 for an effective anti-reflective coating technology, the Carl Zeiss T*, considered one of the most significant inventions of the 20th century.

Carl Zeiss AG was founded in Jena in 1846 by Carl Zeiss, Ernst Abbe and Otto Schott. Due to the Second World War, the original company was split into two parts. One was Carl Zeiss AG in Oberkochen, which had two important subsidiaries in G?ttingen Ahlen and Hallbergmoos. The other is Carl Zeiss GmbH in Jena.

Carl Zeiss is the first constituent company of the Zeiss Group (Zeiss Gruppe) and one of the two largest components of the Carl Zeiss Foundation (Carl-Zeiss-Stiftung). The Zeiss Group is located in Heidenheim and Jena. The other constituent companies of the Carl Zeiss Foundation are the glass manufacturer Schott GmbH and the Jena glassworks (Jenaer Glaswerk), located in Mainz and Jena, respectively.

Today Carl Zeiss has grown to become Europe's largest optical instruments company, with 14,000 employees, factories and subsidiaries in more than 20 countries, including Japan and the United States. Carl Zeiss produces a large range of high-performance lenses. The lenses are used in a wide range of applications, including research, industry, imaging, aerospace and defense. Carl Zeiss is also used in style photography, cinematography (analog and digital), archival photography and quality inspection photography. Whether on Earth or in outer space, the design and performance are among the best available under any environmental conditions.

Classic Zeiss Optics

Since the early 1900s, Zeiss has developed several lens designs (ranging from wide-angle to telephoto), all of which are classic lens designs that have influenced an era of imaging:

Distagon: A reverse-focused, wide-angle lens design, primarily for use from 18mm to 35mm, featuring slight distortion and high central resolution. and high center resolution.

Biogon: A symmetrical design designed for use with RangeFinder cameras, with average resolution but noticeable light loss.

Hologon: Designed for ultra-wide-angle rangefinder cameras, the Hologon has more noticeable light loss than the Biogon and requires filter correction.

Tessar: "Tessar lenses", for the standard lens design, mainly composed of four three-group lenses, features: low distortion and thin.

Planar: mainland China phonetic translation for "Planar", for the standard wide-angle to 135mm telescopic lens design, is a six-piece four-group lens symmetrical Gaussian, at first only f/4.5. Today Planar lens has been made to f/1.4, Planer's features are chromatic aberration correction, perfect, symmetrical design, the Planer lens has been made to f/1.4, Planer's features are chromatic aberration correction, the Planar lens has been made to f/1.4, the Planar lens has been made to f/1.4. The Planer is characterized by perfect chromatic aberration correction, symmetrical design, and very low distortion, and was designed by Paul Rudolph in 1896.

Sonnar: Translated as "Sonnar" in mainland China, it is designed for medium-zoom (135mm) to long-zoom (250mm), featuring no spherical aberration, minimal loss of light, and deformation so low that it is not recognizable to the naked eye, but dispersion must be corrected by APO. Invented in [[1931]] by Zeiss optical designer Ludwig Jakob Beltre, the Vario-Sonner is a zoomable design derived from the Sonner.

Tele-Tessar: A super-zoom (250mm+) design derived from the Tessar, featuring no spherical aberration, very low distortion, very slight light loss, and a very small lens composition, with a minimum lens count of 300mm F/2.8, and using only seven lenses.

Mirotar: A reflex lens for super telephoto. There is a 500mm f/8 for general photography and 500mm f/4.5 and 1000mm f/5.6 for space.

Super Achromat: The best achromatic lens design available, used only on Hasselblad cameras.

Mutar: 1.4x, 1.7x doublers for the Rolleiflex Twin Lens Reflex camera, Rollei 16 miniature camera, and now only for Sony's digital cameras.

Mutargon: Reduction lens (also known as wide-angle lens), currently only used in Sony's digital cameras.

T* Coating: A multi-layer anti-reflective coating developed by ZEISS in collaboration with Rollei.
