Rectangular Optical Light Box

Product Code : SCL-LAO-12071

The Rectangular Optical Light Box is a precision light source instrument used for projecting clear, parallel light beams during geometric optics experiments. Engineered for physics educators and laboratory technicians, this apparatus allows students to trace light ray paths and visually analyze the laws of reflection and refraction.

Product Description

This mechanical laboratory ray box features a durable, ventilated die-cast aluminum housing designed to manage heat dispersal efficiently. It utilizes a low-voltage tungsten halogen or incandescent bulb assembly to emit high-intensity, localized light rays through front and rear optical apertures. The structural design ensures that the projected beams remain sharp and focused across flat laboratory tracking sheets.

This instrument is engineered to accommodate diverse optical slit plates, color filters, and cylindrical elements seamlessly. As a core component of your standard inventory, it offers immense pedagogical value by turning abstract optical equations into sharp, high-visibility ray trails. Adding this unit to your setup provides student groups with a reliable, repeatable method for evaluating light behavior.

Key Features

• Ventilated Aluminum Housing: Features rapid heat dissipation channels to allow continuous, safe operation throughout extended classroom laboratory periods.
• Dual Aperture Layout: Emits clear light rays from both ends simultaneously to maximize student collaboration and experiment efficiency.
• Adjustable Collimating Lens: Equipped with an internal sliding bracket to adjust beam profiles from widely divergent to highly parallel rays.
• Multi-Slit Compatibility: Accurately holds single, triple, or multiple slit plates to create varied light ray configurations.
• Integrated Filter Channels: Designed with built-in sliding tracks to secure color filters for advanced wavelength and color mixing studies.

Technical Specifications

What's Included in the Kit

• 1 x Rectangular Optical Light Box unit with pre-installed 12V bulb
• 1 x Single and triple slit plate combo component
• 1 x Multi-slit comb plate (5 or 7 slits)
• 1 x Primary color filter set (Red, Green, Blue)

Applications / Uses

• Visualizing light reflection paths on plane, concave, and convex mirror surfaces.
• Investigating light refraction indexes through semicircular, rectangular, and triangular prisms.
• Demonstrating the convergence and divergence of light rays using cylindrical lenses within modular optics experiment kits.
• Verifying Snell’s law at refractive boundaries where the formula is defined

How to Use the Rectangular Optical Light Box

1. Place the Rectangular Optical Light Box on a flat, clean white sheet of paper or tracking board.
2. Connect the 4 mm safety sockets to an external low-voltage 12V AC/DC laboratory power supply.
3. Insert the single or triple slit plate into the dedicated front aperture channel slots.
4. Move the internal collimating lens bracket back and forth until the projected light ray paths are perfectly parallel.
5. Place your prism, mirror, or other optical bench accessories into the path of the beam to trace the resulting reflection or refraction profile.

Safety Note: The metal housing can become hot during prolonged usage; always allow the unit to cool completely before handling the bulb or changing slits.

Care & Maintenance

• Cleaning: Wipe down the exterior housing with a dry microfiber cloth; ensure the optical openings are kept free of dust and chalk debris.
• Bulb Replacement: Always turn off the power supply and use a soft cloth when handling a replacement 12V bulb to avoid leaving skin oil deposits.
• Storage: Store the apparatus in a dry, ventilated equipment cupboard to maintain internal electrical components.

Frequently Asked Questions

What power source does the Rectangular Optical Light Box require?

The unit requires an external low-voltage 12V AC/DC laboratory power supply to operate safely.

Can this ray box project multiple light beams simultaneously?

Yes, by inserting the multi-slit plate, the light box can project up to three or five sharp parallel light rays at once.

How do you adjust the beams from divergent to parallel?

You can adjust the ray path by sliding the internal collimating lens rod until the light focus reaches the desired parallel profile.

Does the unit get hot during operation?

Due to the high-intensity bulb, the die-cast aluminum housing will warm up, which is why it features dedicated ventilation slots for heat dissipation.

Are the color filters included with the ray box?

Yes, the basic package comes equipped with a set of primary color filters that slip easily into the integrated front filter slots.
