HemiStar Dome Presentation Lenses

HemiStar Dome Lens Series

Navitar has leapfrogged the current dome lens optical technologies to offer a single lens dome presentation solution for customers that require higher resolution on screen. The Navitar 6.75 mm HemiStar projection lens is designed to project a full 180 degree image onto a hemispherical dome surface in combination with a LCD or single chip DLP projector of up to 1.3” format.

Navitar 6.75 mm HemiStar Lens

Characteristics of the HemiStar lens include:

180 degrees field of view
6.75 mm focal length
F# 3.05
95% center to edge relative illumination
1:1 throw ratio with 1.3" format projector
Optimal projection distance of 15 inches to infinity

The HemiStar lens is compatible with 1.3” format or smaller LCD and single chip DLP projectors with resolution of 1024 x 768 XGA, such as the Christie LX-700 LCD projection with 7000 lumens and 90% brightness uniformity. The lens was designed to be used on-axis to the dome surface; however, due to the outstanding depth of focus characteristics of this lens, it can also be placed off-axis to a dome surface and maintain resolution.
