Double concave glass lenses(pack of 4)

300mm focal length

2" (50mm) diameter

Country of origin: India

Brand: COMETEK

Lens Type: Double Concave (Bi-Concave) / Spherical
Focal Length: -300mm
Diameter: 2 inches (50mm)
Material: Optically worked glass
Quantity: Set of 4 lenses

The Cometek Double Concave Glass Lens Set is a premium optics kit designed specifically for educational physics environments and scientific demonstrations. Crafted from high-quality, optically worked glass, each 2-inch (50mm) diameter lens features a -300mm focal length, ideal for demonstrating light divergence and virtual image formation. Precision-engineered with highly polished faces and safe ground edges, these durable lenses are built to withstand heavy classroom use.

Features

Optically Worked Glass: Made from high-grade, optically true glass for exceptional clarity and accurate light refraction.
Double Concave Design: Features two inward-curved spherical surfaces optimized for diverging incoming parallel light beams.
Polished & Ground Edges: Highly polished optical surfaces with smoothly ground edges for safe handling during lab experiments.
Classroom-Ready Bulk Pack: Comes in a convenient set of 4 lenses, making it perfect for group lab work and school physics stations.

Applications

Optics Demonstrations: Visualizing how diverging lenses spread light rays to create virtual, upright, and diminished images.
Physics Lab Experiments: Perfect for student physics kits to map ray traces and study the lens maker's equation.
Laser Beam Expansion: Utilizing the concave structure to expand or diverge laser beams in simple experimental optical setups.
Focal Length Calculations: Serving as a standard test component for students to calculate negative focal lengths in light benches.
