Lens Designs That Offer High Brightness & Contrast At Navitar we have gained invaluable experience from decades of internal product development and partnerships with key organizations in the projection industry. We excel at producing high contrast and high lumen (fluence) projection lenses. 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 are...

Custom Projection Lens Design Perfect Image Quality by Design The engineers at Navitar know how to create 2K, 4K and 8K projection lenses optimized for specific projection equipment. The secret to designing a near-diffraction limited lens is close interaction between the designer and projector manufacturer to overcome subtle projector nuances. The RGB panels of a projector’s light source are often tuned to the original OEM lens. Obtaining those calibrations will enable a replacement lens to match the light source with the same precision.
