Laser Reflection and Refraction Tank
Laser Reflection and Refraction Tank demonstrates the principle of reflection and refraction. The clear circular acrylic tank has a circular scale graduated on the white base of the tank, making it easy to measure angles. Adjust the pivot-arm mounted laser to any angle along its full 360° range and measure the angle of reflection or refraction. Rotate the laser and observe first a reflected ray, then both a reflected and refracted ray, and finally just a refracted ray. Leveling screws on the tank’s base make leveling quick and easy. The laser is attached to the pivot-arm by a magnet and can be removed for use in other experiments. Instructions included.

Refraction & Reflection Tank
A versatile optical apparatus designed for studying reflection and refraction of light. The apparatus is mounted on a stable base with a circular protractor and pointer for precise angular readings. Supplied with a semicircular acrylic block, prism, and mirror, it enables students to explore core concepts such as Snell’s law, total internal reflection, critical angle, and light behavior through various media. Perfect for hands-on optics experiments in schools and colleges.
Features :
- Circular protractor scale with degree markings for angle measurement
- Rotatable pointer for easy reading of incident and refracted angles
- Sturdy base with graduated markings for positioning
- Includes Student manual.

Demonstration Diffraction 3 in One
For demonstrating the principle of diffraction grating and the way in which its properties are dependent upon the number of lines per unit length. Comprises a card mount 90 x 40 mm approximately with three 16 x 9 mm apertures, each containing a diffraction grating replica. The gratings are of 100 lines/mm. 300 lines/mm and 600 lines/mm, respectively and are protected by cover glasses.

Malus’ Law
Students can investigate the relationship between the intensity of transmitted light and the angle of rotation of two polarizing filters. A graduated cartridge containing two polarizing filters allows students to observe the change in intensity as they are rotated relative to one another. The analyzer allows quantitative readings to be taken using a voltmeter at five-degree intervals as the polarizing filters are rotated from minimum to maximum transmission. The output from the analyzer changes linearly with light intensity and so the resulting data can be used to verify Malus’ Law. Includes instructions.

Newton’s Color Disc
To demonstrate the discovery made by Newton that white light is composed of seven colors. Consisting of a pulley mounted on a metal stand, the seven colored disc is driven by gears connected to a hand driven wheel. When the colored disc rotates, the eye can’t distinguish between individual colors and perceive it as white color.

Newton Colour Disc with Adjustable Clamp
The Newton Colour Disc with Adjustable Clamp is a simple yet effective tool to demonstrate the principle of color mixing. When rotated, the colored segments blend together, visually illustrating how primary colors combine to form white light. Its adjustable clamp allows easy attachment to stands, making it convenient for demonstrations and experiments.
Features:
- Vividly painted color segments for clear visibility
- Adjustable clamp ensures secure and flexible mounting
- Demonstrates the additive mixing of colors
- Durable and lightweight design

Light Kit
Simple kit that helps explain students the principle of reflection and refraction. Using mirrors, lenses, acrylic prism set and a ray box, light can be reflected and refracted in different ways. The acrylic prism set includes a triangular, half-round, double convex and rectangular prism and two double concave prisms all packed in a wooden storage box. A Newton color disc is also provided with this set. The color disc illustrates an important property of light that white light is composed of seven colors. With instructions.

Color Mixing Apparatus
The color mixing apparatus consists of three super bright LED’s Red, Green and Blue to demonstrate the creation of secondary color with a combination of three primary colors. Intensity of these three LED’s are controlled with a microcontroller-based controller. Intensity can be varied from 0-100%. LED’s data can be stored to memory and later restored. The kit consists of two screens (one white Perspex screen and a black aperture screen) and a power supply.
