Yellow layer 0.08mm

K or Black/White layer 1.1mm

Clear protective layer 0.5mm

Lastly the metal protective ring

Black and White Glass Gobos

Black and white gobos are the most popular gobos ordered

They are just 1 single layer of glass with the image lasered out letting the light pass through to project the image.

They are coated "BLACK" on the one side to eliminate reflections.

The Black side must always face away from the LAMP or they will burn.

Greyscale Glass Gobos

Greyscale gobos

They are just 1 single layer of glass with the image lasered out in a Raster or halftone pattern letting the light pass through to project the image. It can create a 3D effect and is a popular way to project real life images, faces, patterns and 3D effects

They are coated "BLACK" on the one side to eliminate reflections.

The Black side must always face away from the LAMP or they will burn.

Black & White &Greyscale Glass Gobos

They are the same as greyscale gobos just with solid areas lasered out as well as a raster or halftone pattern. It can create a 3D effect and is a popular way to project real life images, faces, patterns and 3D effects

They are coated "BLACK" on the one side to eliminate reflections.

The Black side must always face away from the LAMP or they will burn.

Black & White + SPOT COLOUR Glass Gobos

Spot Colours make colour gobos simple and easy to setup, Above is the Samsung logo using only 2 layers,
whereas in the past we would have to use 4 layers Magenta + Cyan to make blue + Black + clear.
With 14 new different dichroic colours we can match pretty closely your logos colours.
We can layer up to 3 layers of colours, but the focal point becomes wider so using 2 layers is the safe maximum.
The Spot Colours are solid layers so the end result is a RICH image. These are very popular and are selling well.
Metal Gobos
For black/white line art projection only, no fine structures, halftones or gradients. The artwork is cut out of the metal disk and the light simply shines through the holes. Metal gobos require bridging (see right) but withstand higher heat than glass gobos. Therefore metal gobos are an alternative for lights that get too hot for glass gobos. But metal gobos look like stencils and are prone to warping after useage.
