STARLAB FiberArc Projector

Introduction

The STARLAB FiberArc Projector uses a revolutionary means of projecting images. By

replacing the standard halogen projection bulb with a combination of a high intensity

arc-lamp light source and a state-of-the-art ber optic light guide, the FiberArc pro-

vides an image clarity that is unsurpassed by any other portable planetarium projec-

tor available today.

While the STARLAB FiberArc uses the same projection cylinders and setting proce-

dures as the STARLAB Standard Projector, it also offers a variety of new options not

previously available. The FiberArc includes separate meridian and cardinal points

projectors that greatly expand the way that the planetarium can be used. In addi-

tion, a variable speed motor allows you to adjust the speed of Earth’s rotation and a

selector switch allows you to change the direction for either the northern or southern

hemisphere. The FiberArc also includes four “gooseneck” side lamps that can be

controlled either individually or in tandem. By manipulating these side lamps into a

variety of positions, you will be able to effectively provide reading light for yourself

and participants without disrupting the night sky. They can be adjusted to simulate

sunrise and sunset and various levels of light pollution. And, they can be adjusted to

illuminate the control panel.

Because the

STARLAB FiberArc

Projector has many

more controls than

the STARLAB Stan-

dard Projector, it is

important that users

familiarize them-

selves with all of the

different components

and maintenance

requirements.
