Glass Fresnel Lenses – Compact Light Focusing & Collimation Detailed
Description:
Glass Fresnel Lenses are flat optical elements with concentric, stepped grooves on one surface that act as individual prisms to focus or collimate light. Compared to traditional convex lenses, they are significantly thinner and lighter, making them ideal for applications where space and weight are critical. Our glass Fresnel lenses offer high thermal stability and excellent performance in lighting, imaging, and solar energy systems.
Key Specifications:
