Optical Plane Glass Slab

Product Code : SCL-LAO-11289
The Optical Plane Glass Slab is a transparent optics component used for demonstrating refraction, lateral displacement and the emergence of a light ray parallel to the incident ray. It is intended for students, physics teachers and laboratory instructors conducting supervised geometrical-optics and ray-tracing experiments.
Product Description
The Optical Plane Glass Slab has two opposite plane faces arranged parallel to each other. A light ray entering the slab obliquely changes direction at the first air-to-glass boundary and refracts again as it leaves the second glass-to-air boundary.
The emergent ray is typically parallel to the incident ray but shifted sideways. This lateral displacement depends on the angle of incidence, slab thickness and refractive index. The exact glass grade, optical properties, dimensions and surface tolerances must be confirmed from the current product specification.
Key Features
- Parallel plane faces: Supports clear demonstrations of refraction through a rectangular transparent medium.
- Lateral displacement study: Shows the sideways shift between incident and emergent ray paths.
- Ray-tracing compatibility: Can be used with pins, a ray box or another suitable narrow-beam source.
- Reusable glass component: Suitable for repeated school and college laboratory sessions.
- Direct visual learning: Connects refraction diagrams with observable ray behaviour.
- No power requirement: The slab itself operates without electricity; a separate light source may be required.
- Curriculum relevance: Supports introductory lessons on Snell’s law, parallel-sided media and optical displacement.

How to Use the Optical Plane Glass Slab
- Place a clean sheet of paper on a stable laboratory table.
- Position the slab on the paper and trace its outline.
- Direct a narrow light ray toward one plane face at an oblique angle.
- Mark the incident ray and the points where the ray enters and leaves the slab.
- Trace the emergent ray after it exits the opposite face.
- Remove the slab and join the marked points to show the refracted path.
- Compare the incident and emergent rays and measure the lateral displacement.
Safety note: Handle the glass slab by its edges. Do not use a chipped or cracked slab, and never direct an intense light or laser beam toward the eyes.
Care & Maintenance
- Clean both plane faces with a soft, lint-free optical cloth.
- Avoid touching the optical surfaces with bare fingers.
- Do not use abrasive cleaners or place the slab against other glass components.
- Store it in padded, dry packaging to prevent scratches and edge damage.

Frequently Asked Questions
What is an Optical Plane Glass Slab used for?
It is used to demonstrate refraction, lateral displacement and the parallel relationship between incident and emergent rays.
Why does a ray shift sideways through a glass slab?
The ray changes direction at both parallel faces. It emerges parallel to its original direction but from a laterally displaced position.
What material is the slab made from?
The product name confirms glass construction. The optical-glass grade and refractive index must be confirmed before purchase.
What affects lateral displacement?
Lateral displacement depends on slab thickness, angle of incidence and the refractive index of the glass relative to the surrounding medium.
Does the slab include a ray box?
No ray box has been confirmed as included. Request an itemised packing list when a light source, tracing sheet or holder is required.
Is it suitable for school physics laboratories?
Yes. It is suitable for supervised secondary-school, senior-secondary and introductory college experiments on refraction.
