Pressed Borosilicate Glass Fresnel Lenses For Stage Light And Traffic Signal Light
Material:
The Pressed Borosilicate Glass Fresnel Lenses are made from high-quality borosilicate glass, a non-alkali glass that contains boron and silicon dioxide. This material provides excellent thermal shock resistance, making it ideal for use in extreme temperature environments.
Quality:
These lenses offer exceptional clarity and durability, with high transparency, low distortion, and excellent scratch resistance. They are designed to maintain their optical integrity even in harsh conditions, such as exposure to chemicals or extreme temperatures up to 550°C.
Function:
The primary function of these borosilicate glass fresnel lenses is to concentrate light energy into a narrow beam for stage lighting and traffic signal applications. They can be used to minimize glare and maximize the intensity of the light emitted, while withstanding high temperatures and harsh environments.
Specific Application:
Their durability and thermal resistance make them an ideal choice for these applications, where exposure to extreme temperatures is a concern. They can also be used as protective covers for sensitive optical instruments or as diffusers for softening harsh light sources.
