Durable Thermal Resistance Borosilicate Fresnel Glass For Stage Lighting Equipment

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.
