Product Code : SCL-W-12390

The Convex Lens +20D is a physics laboratory lens used for demonstrating ray convergence, focal length, image formation, magnification, and positive lens behaviour in ray optics. It is suitable for schools, colleges, STEM laboratories, physics teachers, and students studying light, refraction, lenses, and geometrical optics.

Product Description

The School Equipments Convex Lens is listed as Double Convex Spherical Lenses +20D, product code EL-W-11127. The product description states that it is a double convex spherical lens with optically worked faces, ground edges, 50mm focal length, +20D power, and approximate refractive index of 1.52.

This convex lens helps students observe how parallel rays bend inward and meet at a focus after passing through a converging lens. It is useful for ray tracing, image formation, focal length experiments, magnification demonstrations, and comparison with concave lenses in school optics practicals.

Key Features

• Double convex lens design: Demonstrates converging lens behaviour in practical ray optics experiments.
• +20D stated power: Supports classroom demonstrations of positive lens power and ray convergence.
• 50mm focal length: Listed for experiments involving focal point location and image formation.
• Optically worked faces: Supports clearer observation of light paths and image formation.
• Ground edges: Improves handling safety during supervised school laboratory use.
• Approx. 1.52 refractive index: Provides a stated optical reference value for technical documentation.
• Useful optics accessory: Can be used with ray boxes, optical benches, screens, and lens holders.

How to Use the Convex Lens

1. Place the convex lens in a suitable lens holder or optical bench setup.
2. Align the lens with a ray source, light box, object, or screen as required.
3. Direct parallel or narrow light rays toward the convex lens.
4. Observe how the rays converge after passing through the lens.
5. Adjust the screen position until a clear image or focal point is obtained.
6. Measure the distance from the lens to the sharp focus when required.
7. Compare the observation with a standard convex lens ray diagram.

Safety note: Handle the lens by its edges and do not look directly into bright light sources or lasers. Use glass and optical components only under teacher supervision.

Care & Maintenance

• Clean the lens with a soft, lint-free optical cloth after use.
• Store the lens in a dry case to protect it from scratches and dust.
• Do not drop the lens or press heavy objects against its optical faces.
• Keep fingerprints, chemicals, and abrasive cleaning materials away from the lens surface.

Frequently Asked Questions

What is a Convex Lens used for in physics?

A Convex Lens is used to demonstrate convergence of light rays, focal length, magnification, real image formation, and ray tracing in school optics experiments.

What is the focal length of this convex lens?

The listed focal length is 50mm. This makes it suitable for compact school experiments involving focal point location and image formation.

What is the power of this convex lens?

The product title and description state +20D, but the technical table also shows +2D. Confirm the final lens power before publishing or placing a technical order.

What type of lens is this?

It is listed as a double convex spherical lens. A double convex lens is thicker at the centre and acts as a converging lens.

Can this lens be used with an optical bench?

Yes, it can be used with a suitable lens holder and optical bench for image formation, focal length measurement, and ray optics demonstrations.

What should buyers confirm before ordering?

Buyers should confirm final power, diameter, material, packing quantity, lens holder compatibility, storage case, and any tender-specific specification before purchase approval.
