120 de ani de la primul obiectiv Carl Zeiss

Cel mai renumit producător de lentile împlineşte 120 de ani de la lansarea primului lor obiectiv foto, ce a devenit apoi şi unul dintre cele mai cunoscute şi apreciate, Tessar.

În ultimii ani, producătorul a podus lentile pentru camerele Sony şi pentru Telefoanele Nokia ceea i-a permis să rămână un important producător pe piaţa de obiective, dar şi obiective ‘third party’ pentru camerele foto de top, acestea fiind apreciate pentru calitatea imaginii ridicată şi luminozităţii mari.

120 Years of Lenses from Carl Zeiss

Milestones in lens development

In 1896 Carl Zeiss presented its Planar lens. This lens type is still found in many professional optical tools for photography on Earth and in space. The Planar is the foundation for a variety of Carl Zeiss high-performance lenses with impressive color correction, speed, image flatness and low image distortion.

In 1902, Carl Zeiss submitted a patent for what would eventually become the most famous photo lens of all time: the Tessar. This lens was characterized by a relatively high speed and, for the first time, could take extremely sharp pictures with very little optical effort. It paved the way for camera design miniaturization, a trend that continues today. Millions of lenses in contemporary, high-quality photo cameras and mobile telephones followed the Tessar’s example with its outstanding image quality.

In 1935, Carl Zeiss followed with another breakthrough invention that opened up new possibilities for brilliant imaging: This anti-reflex coating is denoted by the symbol T* on today’s lenses. This vacuum-deposited coating on the lens’s glass surfaces reduces bothersome reflections and stray light in the image, and paved the way for today’s highly complex optical systems.

In 1943, Carl Zeiss also developed a procedure to measure lens image quality with so-called “MTF” curves (modulation transfer function), which numerous manufacturers today use for quality control.

Carl Zeiss even played a pioneering role in computer aided lens design. The introduction of CAD-supported lens development in 1961 replaced lens design by hand and has enabled a far more complex construction and improved interaction between lens elements ever since.

Over the last 15 years, joint ventures with Sony and Nokia have allowed Carl Zeiss lenses to spread widely. Sony has been using ZEISS lenses in its compact cameras and camcorders since 1996. Since 2005, Nokia smartphone and mobile phone users have been taking photographs with integrated ZEISS lenses.
