Lens bi-convex 3.75cm Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-11803

The Light Box (Hodson) - Lens Bi-Convex 3.75cm by Scientifc Equipment is an educational optics accessory designed for demonstrating refraction, convergence of light rays, focal point, focal length, image formation, and ray diagram experiments. It is suitable for school physics laboratories, college science labs, STEM classrooms, optics practicals, and teacher-led demonstrations.

This bi-convex lens accessory is commonly used with a compatible Hodson-style light box or ray box to show how parallel rays bend inward and meet at a focus. It helps students understand convex lens behavior, real image formation, magnification, refraction, and basic optical instrument principles.

Product Description

A bi-convex lens has two outward-curved surfaces and is used to converge light rays. When light from a suitable light box passes through the lens, the rays bend toward the principal axis and may form a focal point or image depending on the setup.

The Scientifc Equipment Light Box (Hodson) - Lens Bi-Convex 3.75cm may be supplied as a bi-convex lens fitted in a holder, lens mount, or compatible optical accessory frame depending on product configuration. It is designed for supervised educational and laboratory optics demonstrations only.

Product Specifications

How to Use

1. Place the Hodson light box or compatible ray box on a stable, dry, and clean laboratory bench.
2. Inspect the bi-convex lens to ensure it is clean, secure, and free from cracks or scratches.
3. Connect the light box to the recommended low-voltage power supply or approved power source.
4. Position the bi-convex lens in the path of single or multiple light rays.
5. Switch on the light source and observe how the rays bend after passing through the lens.
6. Adjust the lens position to locate the focal point where the rays meet.
7. Use a white screen or paper surface to observe image formation where applicable.
8. Measure the distance between the lens and focal point to estimate focal length if required.
9. Record observations and draw ray diagrams showing incident rays, refracted rays, and focus.
10. After use, switch off the light box and allow any warm parts to cool before storing.
11. Clean the lens gently with a soft lens cloth and store it safely in a protective place.

Safety and Handling Instructions

• Use only under teacher, laboratory instructor, or trained adult supervision.
• Do not stare directly into the bright light source or concentrated beam.
• Do not use the lens for viewing the Sun, lasers, UV lamps, welding arcs, or high-intensity light sources.
• Use only with compatible educational light box or ray box equipment.
• Handle the lens carefully to avoid scratches, chips, cracks, or breakage.
• Do not force the lens holder into an incompatible slot or optical mount.
• Keep the lens away from water, chemicals, dust, heat, and rough handling.
• Switch off and disconnect the light box before changing optical accessories.
• Clean only with a soft dry lens cloth; avoid abrasive materials and harsh solvents.
• Store the lens safely to protect the optical surface from damage.
