CTOnews.com, Oct. 24 (Xinhua)-- Superlens is currently a relatively marginal optical technology, mainly sought after by startups and scientists, but the entry of Canon will intensify competition in the industry.

According to Japanese media Mynavi News, Canon demonstrated its support for superlens technology at Canon 2023, and historically, most of the new technological innovations displayed at Canon have been introduced to the market in a short period of time (usually in just a few years).

A superlens is a flat surface designed to replace full-size optics in a completely different way. Basically, hyperlenses reduce the usually large and complex optical structure of standard camera lenses and compress them into a smaller system that uses nanoparticles and hypersurfaces rather than curved optics to bend light. the goal of the hyperlens is to eventually completely eliminate the bulge of the smartphone camera.

According to the photos shared by the media, Canon can make not only the superlenses, but also the equipment needed to produce the superlenses, indicating that the company has invested heavily in this area.

CTOnews.com Note: superlenses (Metalenses) are also called hyperstructured lenses. It is a two-dimensional planar lens structure, which is made of optical elements of focused light on the hypersurface (planar two-dimensional (2D) metamaterials with subwavelength thickness). It is regarded as one of the top ten emerging technologies in 2019.

The superlens has the advantages of thinner volume, lighter weight, lower cost, better imaging and easier integration, which provides a potential solution for compact integrated optical systems. And the polarization, phase and amplitude of light can be controlled by adjusting the shape, rotation direction, height and other parameters of the structure.

The biggest players in the field of superlens technology are Metalenz and Samsung, which has only expressed interest in using the technology in mobile phones.

Metalenz, which is directly engaged in the research and manufacture of superlenses, is perhaps the best-known company in the field. The start-up completed round B financing in October last year and raised an additional $30 million, highlighting its interest in the technology.
