Factory Custom Borosilicate Optical Glass

Factory Custom Dichroic Optical Glass – Borosilicate Colored Glass for Stage Lighting & Entertainment Systems

High-Temperature Resistant Dichroic Glass for Color Lighting Effects
We offer factory-direct custom dichroic optical glass, made from durable borosilicate substrates, engineered for high-performance color filtering under intense lighting conditions. Ideal for stage lights, night bars, theaters, clubs, and disco environments, this colored glass provides vibrant light transmission while withstanding prolonged exposure to high temperatures and strong light sources such as halogen, LED, and HID lamps.

Key Features

• Substrate Material: Borosilicate glass (thermal shock resistant, low expansion)

• Dichroic Coating: Multilayer interference coatings using dielectric materials

• Wavelength Control: Precise color separation (pass/block defined spectral ranges)

• Color Options: Red, blue, green, yellow, magenta, cyan, amber, and custom shades

• Temperature Resistance: Up to 400°C continuous working temperature

• Durability: Scratch-resistant surface, no fading or degradation over time

Customization Options

We support full custom production for OEM or lighting system integrators:

• Available Shapes: Round, square, rectangular, or custom laser-cut profiles

• Thickness Options: 1 mm – 5 mm standard (custom thickness upon request)

• Size Range: From small filters (10×10 mm) to large panels (300×300 mm)

• Coating Type: Hot mirror, cold mirror, bandpass, edge filters, or full spectrum splitters

• Mounting: With/without metal holders or frames for integration into lighting fixtures

• Surface Finish: Polished, frosted, or sandblasted for beam shaping or diffusion

Applications

• Stage & Theater Lighting – color beam shaping for moving head lights, PAR lights, and ellipsoidal reflectors

• Nightclubs & Bars – dynamic lighting effects, decorative projection, or beam coloring

• Disco Ball Systems – rotating light filters for RGB and CMY systems

• Architectural & Event Lighting – ambient lighting color control

• Projection Systems – internal dichroic filters for color image separation
