What's happening
At AMPA 2026, Rich Gobo (Hsin Chuan) demonstrated a single-piece full-colour glass gobo using proprietary 6-micron microdot photolithography, replacing traditional multi-layer stacked dichroic glass. The process delivers HD detail, sharp edges, smooth gradients and heat resistance to 300C, reducing assembly error and image noise versus conventional gobos.

Why it matters for buyers
For a retailer, venue or signage buyer, the practical effect is simple: the unit that reads on your wall at your ambient light, with your artwork, beats the one with the bigger number on the box. Specification order — distance, image size, ambient, then brightness — decides the result.
It also changes lead-time risk. Custom gobos and certified outdoor builds need briefing before the date is fixed; the projector is rarely the long pole, the artwork and certification are.
The technical angle
Colour filters cost output. Every added filter layer absorbs a slice of light; a three-colour stack can lose 40–60% of beam brightness. Quote the filtered lumen figure, not the bare lamp lumen, when comparing.
What to specify
Before you request a quote, lock these down:
- Gobo material: glass for longevity and colour, metal for cheap short runs
- Throw distance from bracket to surface, measured on site — not estimated
- Ambient light level at the hour the projection must read
- Mounting surface and whether the bracket can hold aim
