Durable Thermal Resistance Borosilicate Fresnel Glass For Stage Lighting Equipment
1. Core Material:
Borosilicate Glass: High-performance glass (e.g., Schott Borofloat®) with exceptional thermal stability, low thermal expansion coefficient (CTE ~3.3 x 10⁻⁶/K), and high chemical resistance. The primary material enabling thermal shock resistance.
2. Key Properties:
Extreme Thermal Shock Resistance: Withstands rapid temperature fluctuations (ΔT > 150°C) without cracking – critical when high-power LEDs cycle on/off or dim rapidly during shows.
Precision Optical Performance: Maintains >90% light transmission with minimal distortion. The Fresnel design ensures consistent optical quality across the lens surface.
UV & Heat Stability: Resists yellowing, hazing, or degradation from intense UV/IR radiation emitted by high-output stage LEDs.
Mechanical Durability: Highly scratch-resistant surface preserves clarity. Superior impact resistance compared to acrylic or soda-lime glass.
Chemical Inertness: Withstands cleaning solvents, fog machine fluids, and environmental contaminants common in theatrical environments.
3. Primary Functions:
Beam Shaping & Control: The concentric Fresnel lens grooves efficiently collimate and focus LED light into adjustable spot-to-flood beams for precise stage illumination.
Thermal Stress Management: Prevents lens fracture from sudden heat changes caused by high-wattage LEDs or environmental shifts (e.g., outdoor festivals).
Optical Efficiency: Maximizes light output (lumens) from LEDs, ensuring optimal brightness and color rendering for stage applications.
Equipment Protection: Shields sensitive LED chips and electronics from dust, physical contact, and chemical exposure.
Glare Reduction: Engineered surface minimizes stray light and hotspots.
4. Target Applications (Stage/Entertainment Lighting):
LED Fresnel Fixtures: Primary replacement lens for professional stage, studio, and film Fresnel spotlights.
Moving Heads & Spotlights: Lens module in intelligent fixtures requiring robust optics for pan/tilt movement and rapid thermal changes.
Followspots & Theatre Luminaires: Critical for high-output fixtures where beam quality and reliability are non-negotiable.
Concert/Touring Lighting: Ideal for demanding environments with frequent setup/teardown and variable temperatures.
Architectural Accent Lighting: High-end installations (museums, stages) where precise beam control and durability are essential.
