ffering versatility and fl exibility, Navitar projection lenses are widely used within the amusement, attractions, and entertainment industries. The company works closely with leading projector manufacturers, producers of dome theatre equipment, providers of high resolution, full motion immersive environments and display systems, and the world’s foremost creators, designers, and builders of themed attractions. Its high brightness laser compatible lenses are ideal for immersive attractions, fl ying theatres, and dark rides. “We take the approach of a consultant, or an extension of your engineering team, to deliver exceptional off-the-shelf or custom lens solutions. Determining feasibility, exploring projector options, and confi guring the best lens solution for your project is our expertise. Our goal is the improve the ride experience by providing innovative projection lens solutions,” says Julian. Navitar‘s wide-angel HemiStar fi sheye lenses are used in cove and pit mount planetarium applications, single or multi-channel simulation confi gurations, full dome setups, and complex, dynamic amusement ride systems.
Design capabilities include: Relay and non-relay designs Rectilinear and fi sheye design forms Fisheye lenses with F-theta distortion Uniform pixel mapping at image edge Unique chip sets and color off-sets

“Navitar projections lenses offer precise resolution, accurate colour registration, and consistent quality from center to edge. Our fi sheye lenses have a very large depth of focus, allowing them to maintain sharpness in a variety of settings,” says Julian.
Navitar off the shelf and custom projection lenses have helped customers: • Decrease the number of projectors used to cover a dome surface
• Create seamless display overlap • Achieve superb center-to-edge image resolution • Maximize impact with high-quality images and brightness
• Navitar lenses output crisp images and the true color brightness of the projector.
HemiStar Fisheye Projection Lenses Navitar HemiStar 100°/160°/180°/360° Fisheye lenses allow for single projector/lens presentation solutions for multiple applications. Ideal for projection on small planetarium domes, front projection into immersive environments or globe- shaped digital signage applications, HemiStar lenses allow you to project 360° images inside spherical display systems.
Navitar has developed lenses that work with traditional Xenon based light engines up to 40K
ANSI lumens as well as 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.
????? explains: „Our designs are engineered for peak power and continual thermal cycles through on/off routines. Navitar lenses currently achieve contrast ratios in excess of 400:1.“
3.5X Fisheye Conversion Lens Navitar‘s 3.5X Fisheye Conversion Lens is designed to work with lower cost projectors that do not have replaceable lenses. This is an ideal solution for planetariums that want to upgrade their existing systems, but can‘t afford to buy new projectors or replacement lenses. The new 3.5X Fisheye will also work in many applications where users simply want to project a very wide projector angle onto a curved screen, such as simulation, immersive environments, and amusement parks.
Features: • Excellent illumination at image edge • Low distortion at edge of image • Fully capture all 1920 pixels at widest prime lens zoom
• Exceptional image quality
Applications: • Amusement Rides/Attractions • Museums
