Lens Making at GOTO INC

GOTO INC has been in the lens grinding business for nearly a century.
Over the years, GOTO moved from telescopes, to periscopes, to planetariums and fisheye movie camera and projection lenses.Today, one of the main lines of business for GOTO is the production of quality video projection lenses. This business is so good that GOTO’s optical lab is working full time to keep up with video lens orders!
The dome environment is a challenging one for most lens manufacturers. Especially at the outer edges of a projected image, many dome systems show lack of focus, asymmetrical star images, or chromatic aberration. Likewise, internal reflections can cause contrast loss, and a poorly designed lens can lose light output.
All of these challenges have been met by GOTO for decades now, since GOTO began designing and manufacturing wide angle and fisheye lenses for GOTO Astrovision large format film projectors. In fact, every lens produced for use inside a planetarium is optimized for use on spherical, not flat, surfaces.
Special anti-reflective coatings and internal, motorized irises keep contrast extremely high, and help realize GOTO’s goal of inky-black skies with tiny, beautiful stars.
GOTO’s line of video projection lenses include models designed for the latest 4K projectors, as well as many projectors which can be used in 2K applications. Future lens development continues, so users are encouraged to contact GOTO if they have specific questions or requests for lenses to match any new projectors.

Projector Lens Lineup

GOTO creates many lenses for projectors which can be used in 2K/4K applications for various solutionns. Future lens development continues. Users are encouraged to ask about other projectors!
