Convex Lens 50mm

Product Code : SCL-LAO-12092

The Convex Lens 50mm is a high-transmittance converging optical component used for focusing parallel light rays and demonstrating real image formation. Designed for physics students and educators, this premium biconvex optical lens provides an exceptionally clear plane reference for accurate focal length measurement and light ray refraction tracking.

Product Description

This precision-ground optical element provides a reliable mechanical tool for fundamental and advanced light refraction studies. Ground from high-purity crown glass, the lens maintains a completely uniform refractive index across its volume to eliminate structural beam distortion. The precision-polished dual convex surfaces converge incoming parallel light paths symmetrically, creating clean real focus lines that are easy to map with standard light sources.

For secondary schools and universities updating their standard inventory of physics lab equipment, this glass lens provides exceptional pedagogical value. It allows student cohorts to execute highly reproducible geometric ray tracing laboratories without the mechanical warping or cloudiness common with cheap plastic alternatives. The durable silicate structure easily tolerates regular classroom handling, making it a permanent baseline asset for wave mechanics workstations.

Key Features

• Premium Crown Glass Build: Ground from high-purity crown silicate glass to ensure maximum beam transmission and minimal internal flaws.
• True Bi-Convex Design: Features symmetric dual outward curvatures designed specifically to maximize ray convergence tracking precision.
• Standardized 50mm Aperture: Fits seamlessly into universal lens rings, holders, and standard optical bench accessories.
• Ground Edges for Safety: Designed with fine perimeter ground borders to prevent structural chipping and ensure safe student handling.
• Anti-Scratch Polish Finish: Hard glass structure provides excellent resistance against fine abrasions from plastic storage dividers or alignment calipers.

Technical Specifications

What's Included in the Kit

• 1 x Convex Lens 50mm diameter optical element
• 1 x Protective lint-free storage container
• 1 x Microfiber optical cleaning cloth

Applications / Uses

• Tracing convergent beam geometries to verify the fundamental lens maker's equation under multiple boundary configurations.
• Measuring real focal lengths by tracking the position where parallel light rays converge to a sharp focal point on standard screens.
• Calculating object distances and image distances to satisfy the standard thin lens formula:
• Determining the linear magnification ($m$) of real images across varying distances via the geometric relation:
• Integrating smoothly inside high-resolution optics experiment kits to construct complex multi-lens optical systems.

How to Use the Convex Lens 50mm

1. Clean the lens surfaces thoroughly with the provided microfiber cloth before beginning your laboratory configuration.
2. Insert the 50mm convex element securely into a universal lens holder ring attached to your tracking rail slider.
3. Position an active light source or multi-beam laser ray box up-beam from the convex lens.
4. Turn on the light source to observe the parallel light rays converge inward as they pass through the glass element.
5. Move a white projection screen along the track until the inverted image resolves into a perfectly sharp focus point.
6. Read the coordinate markings along the bench scale to calculate the exact focal length indices.

Safety Note: Never use the convex lens to focus direct sunlight or high-power unattenuated lasers onto flammable materials or human skin, as the concentrated energy can cause rapid thermal burns.

Care & Maintenance

• Cleaning: Dust the glass carefully using standard lens blowers or clean compressed air before wiping with a specialized lens cleaner solution.
• Storage: Always store the lens inside its padded protective container to shield the polished faces from metal tools or accidental abrasions.
• Handling: Never touch the polished optical face with bare skin; hold the element strictly by its ground outer rims to avoid leaving skin oil deposits.

Frequently Asked Questions

What does a positive focal length mean for this convex lens?

A positive focal length indicates that parallel light rays passing through the lens converge toward a real physical focal point located on the opposite side of the incoming light.

Can I project a real image directly onto a screen using this lens?

Yes, a standalone convex lens naturally produces real, inverted images of objects placed beyond its principal focal point, which can be projected directly onto a physical surface.

Is this lens made of glass or optical polymer plastic?

The optic is ground from premium crown silicate glass, which provides superior refractive stability, better scratch resistance, and higher clarity than cheap plastic alternatives.

What size lens holder ring is required for this optic?

This lens features a precise 50 mm outer diameter, making it fully compatible with standard universal lens ring clips and standard bench holders.

Does this lens work with green and blue laboratory lasers?

Yes, the high-transmittance optical crown glass easily handles all visible light wavelengths cleanly without distorting or absorbing the color frequencies.
