Projector Application Diagrams Our ultra wide-angle HemiStar lenses are used in cove and pit mount planetarium applications, single or multi-channel simulation configurations, full dome setups, and complex, dynamic amusement ride systems. Whatever your application, Navitar has a solution. Design capabilities include: • Relay and non-relay designs • Rectilinear and fisheye design forms • Fisheye lenses with F-theta distortion • Uniform pixel mapping at image edge • Unique chip sets and color off-sets • Panel size variations in light engines • Custom internal masking requirements • Tolerance...

Custom Projection Lens Design Perfect Resolution by Design The lens designers at Navitar understand the exact design requirements for 1080p, 2K and 4K projection lenses. The secret to a near-diffraction limited lens design is in part from the lens designer working closely with the projector manufacturer to overcome subtle projector nuances when designing lenses. For example, in most cases the RGB panels within the light engine are tuned for factory lenses. This must be considered when designing replacement lenses. Tight Color Registration - All the Way to the Corners Navitar understands the...

High Contrast and High Fluence Projection Lens Design Through extensive internal development efforts, acquisition, and partnerships with projector manufacturers and customers in the premier digital cinema market, Navitar has gained expertise in high contrast/ high lumen (fluence) projection lens design. Navitar has developed lenses that work with traditional Xenon based light engines up to 40K ANSI lumens as well 6P platforms up to 60K ANSI lumens. We have over 500 lenses installed on 1.38” DLP platforms for digital cinema applications which see 35K ANSI lumens on a daily basis. Our designs...
