Custom Gobs 1 of 4
 OPTI Custom Gobos
In addition to the standard range of OPTI Effects,
shown on the site, OPTI also manufacture custom
glass gobos using a wide range of processes for our
own, as well as other lighting manufacturers,
equipment.
Gobo is a theatrical word for a slide. Usually circular
they fit into a projector and with light passing through
them they are focussed to create a projected image.
The use of gobos has become extremely popular for
brand enhancement and promoting messages in retail,
exhibition, leisure, corporate and architectural
environments.

The gobo formats that we produce for use in our own
projectors are 50mm diameter single gobos, 50mm and
3 inch Cassettes - which combine two glasses, one
static and one rotating, and 6 inch Wheels.
Duplicate 35mm slides are also offered for use in all
our projectors, like the OPTI Solar 250 and the OPTI
GoBoShow, except the OPTI K4. These fit into the
same holder as 50mm gobos on various accessories
and are an economic solution for a few days use at
trade shows and other short term promotions or events.
For longer term use in any OPTI projector, or use in
the OPTI K4 projector, glass gobos must be used.
Many other sizes of gobo exist. We are able to offer
most commonly found formats, such as those listed here,
from stock. More unusual sizes are available to order.

For photographic half-tone images use Photoshop® or Paint Shop Pro®, saving the images, at 1,200dpi, as‘jpg’s’ for e-mailing or transmitting via ISDN.
When making an enquiry or ordering please let us know which type of projector the gobo is for. For example
an OPTI Solar 250. We will also need to know if the image will be back or front projected and whether or
not this will be via a mirror. All this information helps us to get it right first time for you.
