150mm LENSE - GOBOSHOW OR GOBOPRO

150mm Lens [GS6192]

Very narrow angle lens
for the GoBoPro and GoBoShow projectors

All OPTI Kinetics projectors are supplied with an 85mm focal length lens as standard.  The 150mm lens, GS6192, is an alternative focal length lens for the Goboshow or GoboPro Projectors.

nb If a narrower lens is required, note that K series lenses can be fitted to the GoBo range using the Lens Mount LA528037 (GS6100).

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.
