What types of stage lighting glass components can we produce?
BO-GLASS manufactures precision glass optics for stage lighting, including convex, Fresnel, step, and TIR lenses. Our chemically strengthened glass exceeds EU standards, withstanding 2J+ impact and 120°C thermal shock. We support your projects from prototyping to mass production.
Primary Optical Components
Convex Lenses: For basic focusing and beam shaping.
Fresnel Lenses: Create a soft-edged, adjustable spot-to-flood beam. Known for their stepped design that reduces weight and heat retention.
Step Lenses: A more efficient version of the Fresnel, often used in ellipsoidal spotlights.
TIR (Total Internal Reflection) Lenses / Collimators: Typically made of optical glass ， these are highly efficient for collecting and collimating LED light into a controlled beam. Often used in LED pars, spots, and moving heads.
Dichroic Reflectors: Cold-mirror reflectors that allow infrared heat to pass through while reflecting visible light, reducing heat on the stage and object.
Aluminized Glass Reflectors: Provide a highly reflective and durable surface for shaping and projecting light from the source.
Protective & Filter Components
Dichroic Color Filters: Thin-film coated glass that transmits specific wavelengths (colors) of light while reflecting others, used for creating vibrant, fade-resistant colors without gels.
UV Filter Glass: Blocks ultraviolet radiation, which can be harmful to both eyes and materials.
Heat Shield Glass (Infrared Filter): Placed between the lamp and other components to protect them from extreme radiant heat.

FAQ: Custom Glass Optics for Stage Lighting
What types of glass components can you manufacture for stage lighting fixtures?
Lenses: Convex, Fresnel, Step, and TIR (Total Internal Reflection) Lenses.
Reflectors: Dichroic (Cold-Mirror), Aluminized, and Ellipsoidal Reflectors.
Protective & Filter Components: Cover Glass, Dichroic Color Filters, UV Filters, and Heat Shield Glass.
Why is chemical strengthening important for stage lighting glass?
What are the benefits of using your TIR lenses and dichroic reflectors?
Dichroic Reflectors & Filters: Provide vibrant, consistent, and fade-resistant colors without gels. The “cold-mirror” effect also passes IR heat away from the stage, protecting both the fixture internals and the performers.
Can you create custom glass optics based on our design specifications?
What is your typical lead time for prototypes and mass production?
