Distance Calculation Formula
Please note all [OPTI] GoboPro and GoboPro+ can be used with
52.5mm barrel lenses so there may be other lenses available.
Gobos & Cassettes
All [OPTI] GoboPro and GoboPro+ projectors accommodate an
outside diameter of 50mm (+0 -0.1mm) rotatable gobo, and a
44mm OD (+0 -0.1mm) static gobo which can be purchased from
[OPTI] Kinetics directly. A 50mm cassette holder is supplied with
every GoboPro and GoboPro+ projector which all gobos need to
be inserted into to be projected.
Attaching the complete cassette to the projector
Engage the cassette onto the drive gear at the bottom and gently
snap the cassette onto the projector.
Removing the complete cassette from the projector
Insert a fingernail or flat blade screwdriver into the gap between
the cassette holder and the top of the cassette and gently lever out
the cassette.
Additional cassette holders are available.
Inserting a Gobo into the cassette holder
Line up the gobo with one of the tabs on the cassette holder and
gently press the gobo using your thumbs level with the two other
tabs. When the gobo is fully inserted, you will hear a click noise.
If you are inserting a 44mm static gobo, turn the cassette holder
over and gently push into the back of cassette rotator. It is
recommended that the two image faces of the 44mm and 50mm
gobo are placed next to each other within the cassette.
It is recommended to use a separate cassette holder for each
gobo. It is recommended to warm the cassette holder before
inserting your own gobo. For example leave the cassette holder on
the radiator for a few minutes.

Removing the gobo from the cassette holder
If the gobo has just been recently used on the [OPTI]
GoboPro/GoboPro+ projector, please wait unl it is cool enough
to touch before aempng to remove the gobo from the cassee
holder. That said; it is easier to remove the gobo from the cassee
holder if it is slightly warm. Leaving the gobo on the radiator for a
few minutes can help. To remove the static 44mm gobo (if fitted)
firmly tap the cassette holder (zoom gobo facing up) onto a
hard surface. To remove the rotating 50mm gobo, gently
press the gobo out with your thumbs from the rear.
