Overview of B/W Gobo technologies (FAQ):  

Drix manufactures etchable aluminum-on-glass gobo materials for use in the lighting industry.

Such blank (unpatterned) gobo's consist of a substrate of borosilicate glass, covered with a metal layer and optionally positive photoresist.

These gobo's are manufactured in various sizes to accomodate different lighting fixtures. 

There are two methods for patterning gobo’s:
- Laser ablation.
- Chemical etching.

Chemical patterning can be done by exposing through a film with ultraviolet light, then the photoresist layer is developed, after that the aluminum layer is etched and then the photoresist layer is stripped. Full technical support is available for correct chemical processing and etching with high resolution, high consistency and low defect count. 

Some of the Drix materials are suitable for laser ablation, others are suitable for chemical etching.
