100mm FOCUS LENSE - SOLAR 250 or 100C

100mm FOCUS LENS [FG6170]
for use with Solar 250 or 100C Projectors

Provides a narrower projection angle
for larger venues for your Solar series projector

All OPTI Kinetics projectors are supplied with an 85mm focal length lens as standard.  The 100mm lens, FG6170, is an alternative focal length lens for the Solar 250 or 100c Projectors.

If you require an even narrower projection, combine this lens with the Solar Zoom Attachment LA528134 (FG6120).

Lens Angles

The focal length of a lens determines how wide an angle the image is projected. In simple terms the larger the number of the focal length of the lens the narrower the beam. The lower the number the wider the angle. This angle is called the 'inclusive' angle. The 'inclusive angle' of each lens can be plotted on design drawings to determine the projected image size.

Lens Selection Calculations

This simple graph shows approximate image sizes at various projection distances for all of the lenses in the OPTI range.
