Set of three lenses
Product Code : SCL-OS-12874
The Set of three lenses is a physics laboratory optics set used for studying refraction, focal length, image formation, converging rays, diverging rays, and ray diagrams. It is suitable for schools, colleges, science laboratories, STEM classrooms, teachers, students, and laboratory instructors.
Product Description
The Set of Three Lenses by Educational Instrument is designed to help students observe how light bends when it passes through transparent curved surfaces. The set allows comparison of different lens behaviours, including how convex and concave forms affect the direction of light rays.
This product is listed as Set of 3 Plexiglass Lenses, product code SCL-OS-12820. It is commonly used with a ray box, light source, optical bench, screen, white sheet, or lens holder for classroom optics experiments.

How to Use the Set of three lenses
Place one lens on a clean, flat surface or in a compatible lens holder.
Direct a ray box, LED light source, or suitable classroom light source toward the lens.
Observe the path of light before and after it passes through the lens.
Use a white sheet or screen to trace the refracted rays.
Identify whether the selected lens converges or diverges the light rays.
Mark the focal point and measure the approximate focal length where applicable.
Repeat the experiment with the other lenses and compare their optical behaviour.
Safety note: Use the lenses under teacher supervision. Avoid scratched optical surfaces, direct viewing of bright light sources, and rough handling during student practicals.
Care & Maintenance
Clean each lens with a soft, dry optical cloth after use.
Do not touch lens surfaces with oily or dirty fingers.
Store lenses in a dry protective box or laboratory cabinet.
Keep lenses away from abrasive materials, excessive heat, and heavy objects.
