The plastic lens holder is an optical laboratory accessory used for positioning a compatible lens during light, image-formation and focal-length experiments. It is intended for school, college and university physics laboratories that need a simple support for keeping an optical lens upright and aligned during supervised practical work.
Product Description
The STEMAids Plastic Lens Holder supports lenses used in introductory ray-optics experiments. A correctly positioned holder keeps the lens stable while students align a light source, lens and screen along a common optical axis. This improves observation and reduces unwanted movement during measurements.
The holder is identified as plastic construction. Its confirmed lens-diameter range, aperture size, base design, dimensions and optical-bench compatibility are not currently published. Buyers should verify these details against the lenses and experimental setup already used in their laboratory. Related equipment is available in the STEMAids physics laboratory products range.
Key Features
- Plastic construction: Provides a lightweight lens-support format for routine educational use.
- Stable lens positioning: Helps keep a compatible lens upright during optical demonstrations and measurements.
- Improved alignment: Supports placement of the lens between a light source, object and projection screen.
- Hands-on learning: Allows students to adjust component positions and observe changes in image formation.
- Reusable laboratory accessory: Suitable for repeated supervised experiments when handled and stored correctly.
- Simple operation: Requires no electrical supply or complex setup.
- Broad optics relevance: Can support compatible convex- and concave-lens activities, subject to holder size.

Applications / Uses
- Holding a compatible convex lens during focal-length experiments.
- Supporting concave-lens demonstrations with the required auxiliary optics.
- Studying real and virtual image formation.
- Investigating object distance, image distance and magnification.
- Aligning lenses for refraction and ray-tracing activities.
- Supporting classroom demonstrations and student laboratory practicals.
How to Use the Plastic Lens Holder
- Place the holder on a level laboratory bench or compatible optical support.
- Check that the lens diameter and edge profile fit the holder without force.
- Insert the lens carefully and confirm that it remains upright.
- Position the light source, object, holder and screen along the same optical axis.
- Move the holder or screen gradually until the required image or ray pattern is visible.
- Measure the object and image distances from the optical centre of the lens.
- Remove the lens with clean hands and return it to its protective case after use.
Handling note: Do not force an oversized lens into the holder. Handle lenses by their edges and keep intense light sources away from eyes and heat-sensitive plastic parts.
Care & Maintenance
- Wipe the holder with a soft, dry or slightly damp cloth.
- Keep the holder away from solvents and excessive heat unless material compatibility is confirmed.
- Store it flat or upright in a covered cabinet to prevent deformation and dust buildup.
- Inspect the lens-contact points before each practical.

Frequently Asked Questions
What is a plastic lens holder used for?
It is used to keep an optical lens upright and positioned during experiments involving refraction, focal length, magnification and image formation.
What material is the holder made from?
The product is identified as a plastic lens holder. The exact polymer grade is not published and should not be assumed.
Which lens sizes fit this holder?
The compatible lens-diameter range is not currently published. Confirm the lens diameter and holder opening before ordering.
Can it hold both convex and concave lenses?
It may support either type when the lens dimensions match the holder. Compatibility should be verified for each lens.
Is a lens included with the holder?
The available information does not confirm that a lens is included. Treat the lens as a separate item unless the quotation states otherwise.
Can this lens holder be used in schools?
Yes. It is suitable for supervised school and college optics practicals when used with compatible lenses and light sources.
