The convex optical lens 50mm is a converging optical component used for focusing light and studying real or virtual image formation. It is intended for secondary-school, college and university physics laboratories that require a reusable lens for focal-length measurement, ray tracing, magnification and optical-bench experiments.
Product Description
The STEMAids Convex Optical Lens 50mm is thicker at its centre than at its edges. Parallel rays passing through a convex lens converge toward a principal focus on the opposite side, subject to the lens profile, refractive index and surrounding medium.
The nominal product size is 50 mm. However, the available information does not confirm whether this value represents overall diameter, clear aperture or mounting size. The focal length, optical power, lens material and surface finish must be verified before quantitative use. Browse related physics laboratory products for compatible optics apparatus.
Key Features
- Convex optical profile: Converges parallel incident rays for practical optics demonstrations.
- Nominal 50 mm size: Provides a laboratory-scale lens format; the precise measurement basis requires confirmation.
- Image-formation capability: Produces real or virtual images depending on the object position relative to the focal point.
- Focal-length experiments: Supports suitable displacement, distant-object and optical-bench methods.
- Hands-on ray tracing: Helps learners connect physical observations with standard convex-lens diagrams.
- Passive operation: Requires no battery or electrical connection.
- Reusable laboratory component: Suitable for repeated supervised practicals when protected from scratches and impact.

How to Use the Convex Optical Lens 50mm
- Inspect the lens for cracks, chips, dust or fingerprints.
- Secure it in a compatible holder without applying excessive pressure.
- Align the lens centre with the object, light source and observation screen.
- Position the object beyond the expected focal point when forming a real image.
- Move the lens or screen gradually until the image appears sharp.
- Measure object and image distances from the optical centre of the lens.
- Repeat the observation before calculating focal length or magnification.
- Remove the lens by its edges and return it to protected storage.
Safety note: Never look through the lens at the Sun, a laser or an intense lamp. A convex lens can concentrate light and create an eye, skin or fire hazard.
Care & Maintenance
- Remove loose dust with clean air or a soft optical brush.
- Clean the faces using lens tissue and approved optical cleaner.
- Store the lens in a padded, dry and dust-free container.
- Protect the optical surfaces and edges from impact and abrasion.

Frequently Asked Questions
What is a convex optical lens used for?
It is used to converge light and study focal points, magnification and real or virtual image formation.
What does 50 mm mean for this lens?
The product name specifies a nominal 50 mm size. Confirm whether it refers to overall diameter, clear aperture or mounting diameter.
What is the focal length of the lens?
The focal length and optical power are not published. Request the verified value before using the lens for calculations.
Is the lens made from optical glass?
The material and optical grade are not verified. Glass, acrylic or another optical material should not be claimed without confirmation.
Can this convex lens form a real image?
Yes. A real image can form on a screen when a real object is placed beyond the focal point of a suitable convex lens.
Is a lens holder included?
The inclusion of a holder or mounting ring is not confirmed. Check the approved bill of materials before ordering.
