Glaswerk GmbH was founded to create cinema lenses that combine cinematographers’ aesthetic preferences with mechanical reliability and post-production efficiency. To achieve this vision, founders Viola Evang and David Kellermann collaborated with experienced engineers to develop their debut front anamorphic lens series, ONE.

The engineering team brings extensive expertise in lens design, stray light and ghost analysis, lithography, and machine vision, covering all essential optical, mechanical, and electrical disciplines to fulfil Glaswerk’s objectives.

Glaswerk collaborates with seasoned design firms for optical lens development, catering to the technological and aesthetic needs of the film industry.

Their designs, including Christoph’s Leica Noctilux 50mm f0.95, have seen widespread use. Additional information is available on the HOC Optik and Türck Engineering websites.

Glaswerk significantly benefited from Ingenieurbüro Bischoff’s extensive experience in designing precision opto-mechanics for lithography lenses and space technology, ensuring our lenses perform reliably in demanding on-set environments.

Their design philosophy, which prioritizes ease of assembly and maintenance, minimizes downtime, benefiting Glaswerk and our clients alike.

Since 2018, Glaswerk has collaborated with Hembach Photonik to not only minimize stray light but also to enhance flares (technically referred to as ghosts) for visually appealing images.

Hembach’s ghost analysis guides the selection of lens elements for special coatings to achieve the desired flare effects and enables a consistent integration of live-action and VFX shots with visible flares.

During numerous discussions with our customers, it became clear that metadata needed to be included in the release version of our lenses. Fortunately, we found the perfect project partner in Konstruktiv.

Their software expertise enabled full DCS format integration, while their proficiency in electrical design ensured highly reliable components that seamlessly interfaced with the mechanical design.

Glaswerk lenses require optics and mechanics that match the high quality of their designs, as well as assembly and adjustment in clean rooms to ensure that this quality is met or exceeded.

Spectros in Switzerland is the ideal partner for this process, not only because of their technical expertise but also thanks to their great and dedicated team.
