Convex Lens Manufacturer,Supplier and Exporter in India
Product Code : SCL-LAO-11234
A convex lens is thicker near its centre than at its edges and bends parallel incident rays towards a principal focus. In laboratory activities, students can position the lens between an illuminated object and a screen to observe real images and investigate how image position and size change with object distance.
The available product information confirms 50 mm and 75 mm diameter options. Focal length, lens material, curvature, centre thickness, edge finish and optical tolerance are not specified. Buyers should confirm these parameters before selecting the lens for a prescribed experiment, replacement requirement or institutional tender.
Key Features
Two diameter options: Offered in nominal 50 mm and 75 mm sizes for different laboratory arrangements.
Converging optical form: Directs suitable incident light rays towards a principal focus.
Supports image formation: Enables real-image demonstrations using an object, lens and screen.
Useful for focal-length activities: Supports suitable experimental methods for estimating focal length.
Visual optics learning: Helps students connect ray diagrams with observable image behaviour.
No electrical supply required: The lens operates as a passive optical component.
Suitable for repeated practical work: Can be reused when its surfaces and edges are handled carefully.

What's Included in the Kit
One Convex Lens in the selected 50 mm or 75 mm diameter
A lens holder, optical bench, illuminated object, screen, metre scale and light source are not confirmed as included.
Applications / Uses
Demonstrating convergence of light rays
Locating the principal focus of a convex lens
Estimating focal length by suitable laboratory methods
Studying real and virtual image formation
Comparing image size at different object distances
Verifying the lens formula with compatible apparatus
Supporting ray-optics and geometrical-optics lessons
How to Use the Convex Lens
Mount the lens vertically in a compatible lens holder.
Align the illuminated object, lens and screen along the same optical axis.
Move the screen until a sharp real image appears.
Measure the object distance and image distance from the optical centre.
Repeat the observation at several object positions.
Record the image orientation, size and sharpness.
Use the readings for the required focal-length or lens-formula calculation.
Safety note: Never look at the sun through the lens. A convex lens can concentrate sunlight and may cause eye injury, burns or ignition of nearby material.
Care & Maintenance
Handle the lens by its edges to reduce fingerprints.
Clean optical surfaces with a soft lens cloth.
Store the lens in a padded, dry compartment.
Do not place the lens face-down on a hard surface.
Why Choose Lab Exports
Lab Exports manufactures and exports scientific instruments, physics experiment apparatus, educational models, science kits and STEM laboratory products.

The required diameter, focal length and mounting arrangement should be confirmed in the quotation before procurement.
Frequently Asked Questions
What is a convex lens used for in a physics laboratory?
A convex lens is used to demonstrate light convergence, refraction, focal length and image formation. It can produce real or virtual images depending on the object position.
Which convex lens sizes are available?
The available product listing shows 50 mm and 75 mm diameter options. Select the size according to the lens holder and experiment setup.
What is the focal length of the lens?
The focal length is not specified. Buyers requiring a particular focal length should include that value in the enquiry.
Is a lens holder included?
A lens holder is not confirmed as part of the supply. Request a component-wise quotation when a complete experimental setup is required.
Can this lens form a real image on a screen?
Yes. A convex lens can form a real, inverted image on a screen when the object is positioned beyond the focal point.
Can students use the lens to observe the sun?
No. Looking at the sun through a convex lens can cause permanent eye damage. Concentrated sunlight can also cause burns or fire.
