Optical Glass Colour Filter

What is an Optical Glass Colour Filter?

Optical glass colour filters are precision-engineered glass components that selectively transmit light of specific wavelengths while blocking others. These filters are widely used in stage lighting systems to achieve vibrant, dramatic, or mood-setting effects.

Unlike plastic filters that degrade over time due to heat, our glass colour filters maintain consistent color output and thermal resistance, even under high-power lighting setups.

TIHOTOPTICS offers a wide range of custom colour filters made from high-quality borosilicate or soda lime glass, designed for maximum durability and optical clarity.

What is a Colour Filter Used for in Stage Lighting?

Colour filters are an essential tool in the stage lighting industry. They:

• • Modify the color of the light beam to set different scenes or moods

• • Support theatrical lighting effects for concerts, theater plays, exhibitions

• • Enable creative visual impact for architectural and decorative lighting

• • Filter unwanted wavelengths to protect lenses or sensitive detectors

Whether it’s a warm amber for a romantic scene or a deep blue for dramatic suspense, glass colour filters deliver the precision and stability lighting designers rely on.
