60mm FOCUS LENSE - SOLAR 250 or 100C

60mm FOCUS LENS [FG6150]
for use with Solar 250 or 100C Projectors

Provides a wider angle projection from your Solar series projector
Useful for projecting across a wall or screen at closer proximity.

All OPTI Kinetics projectors are supplied with an 85mm focal length lens as standard.  The 60mm lens, FG6150, is an alternative focal length lens for the Solar 250 or 100c Projectors.

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.

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