Glass Prism (Equilateral, 50 × 50 mm)

Product Code : SCL-LAO-12095

The Glass Prism (Equilateral, 50 × 50 mm) is a high-transmittance optical component used for demonstrating light dispersion and measuring refractive indices. Designed for physics educators and university science students, this prism provides an exceptional physical medium for spectrum separation and quantitative wavelength analysis.

Product Description

This premium equilateral prism is engineered specifically for high-resolution spectroscopy and wave optics demonstrations in secondary schools and colleges. Fabricated from high-density optical glass, the block features excellent structural clarity and a highly uniform refractive index throughout its entire volume. Each of its three rectangular optical faces is ground and precision-polished to optical flatness to minimize light scattering, ensuring that emerging spectral lines remain sharp and distinct.

For institutions looking to expand their inventory of standard physics lab equipment, this component delivers superior pedagogical value. It shifts abstract optical mathematics into a highly visual physical display of primary colors, serving as a baseline tool for general wave mechanics courses. The robust silicate glass layout coordinates smoothly with diverse spectrometers and classical laboratory instruments.

Key Features

• High-Optical Purity Glass: Fabricated from premium optical silicate glass to guarantee maximum beam transmission and minimal internal bubble flaws.
• True Equilateral Profile: Machined with an exact angle layout to ensure highly predictable light ray paths and symmetric refraction boundaries.
• Optically Polished Faces: Features three precision-polished sides to deliver crisp, clear polychromatic light separation without structural distortion.
• Generous 50 mm Dimensions: Provides a large operational surface area that easily captures wide, uncollimated ambient light beams or broad laser arrays.
• Shatter-Resistant Edge Bevels: Designed with fine protective edge chamfers to protect student hands and prevent minor chipping during cleanups.

Technical Specifications

What's Included in the Kit

• 1 x Glass Prism (Equilateral, 50 × 50 mm) optical element
• 1 x Velvet-lined rigid protective storage container
• 1 x Microfiber optical lens wipe
• 1 x Technical data card detailing dispersion indices

Applications / Uses

• Demonstrating how a dense glass environment breaks white polychromatic light into its component spectral wavelengths.
• Determining the specific refractive index of optical glass by observing the angle of minimum deviation using the equilateral relation:
• Verifying Cauchy's classical dispersion parameters across visible light frequencies within high-resolution optics experiment kits:
• Demonstrating total internal reflection paths when setting the angle of incidence past critical thresholds.

How to Use the Glass Prism (Equilateral, 50 × 50 mm)

1. Clean the polished glass faces thoroughly using the provided microfiber wipe before setting up your experiment.
2. Place a white tracking worksheet flatly onto a level laboratory bench or standard prism table.
3. Position the Glass Prism (Equilateral, 50 × 50 mm) upright on one of its triangular frosted bases.
4. Direct a narrow, concentrated white light ray from a lamp or ray box toward one of the polished rectangular faces at an oblique angle.
5. Observe the emergent ray paths break apart spatially into a vibrant rainbow spectrum on the tracking board sheet.
6. Trace the incoming, internal, and emerging ray paths with a pencil to calculate your final geometric data.

Handling Note: Hold the prism exclusively by its top and bottom triangular frosted surfaces to avoid leaving skin oil micro-residues on the polished viewing windows.

Care & Maintenance

• Cleaning: Remove superficial dust particles using clean pressurized air before wiping with a lens fluid cleaner; avoid paper towels that introduce micro-scratches.
• Storage: Always return the optical block inside its velvet-lined protective container to prevent abrasive contact with other metallic tools.
• Handling: Keep the hard silicate glass clear of rough stone laboratory benchtops; place it down exclusively on soft felt mats or paper templates.

Frequently Asked Questions

Why does an equilateral prism separate white light into different colors?

The prism separates light because different colors have different wavelengths, and each wavelength experiences a distinct refractive index when entering the glass, causing violet light to bend significantly more than red light.

What are the exact structural measurements of this glass block?

The prism features a true equilateral profile where each of the three main rectangular polished faces measures exactly 50 mm in length and 50 mm in height.

Can this equilateral prism be used with a standard spectrometer table?

Yes, its 50 mm footprint fits comfortably onto standard universal prism alignment platforms used alongside classical spectroscopy instruments.

Is this optic made from glass or acrylic plastic?

This optic is ground from premium optical silicate glass, which provides superior refractive stability, higher scratch resistance, and greater clarity than commercial plastic alternatives.

Are all the faces of the prism polished clear?

The three side rectangular faces used for ray entry and transmission are polished to full optical clarity, while the top and bottom triangular bases feature a fine frosted finish for safe handling.
