Excellent for showing refraction and internal reflection in water, and to measure its refractive index. These clear hollow acrylic refraction cells have uniform wall thickness to eliminate any distortion. Dimensions: 12 cm Diameter x 2.5 cm Height
Polarized Sheet 12" X 17" 6mil Thick. Polarizing filters are used for experiments involving birefringence, light scattering, polarized light experiments, light reflection, Brewster's angle and how polarized sunglasses work. Same linear polarized material as our Polarized 3-D glasses and our polarized 2" X 2" slides. 12" x 17" sheets.
The Ajax Scientific Polished Glass Double-Convex (Bi-Convex) Lens has two outwardly curved surfaces that converge light rays to a point for demonstrating optical principles and effects for students. The lens has a focal length of 100mm and is 50mm in diameter. It is made of polished glass with ground edges. Lenses are used in scientific experiments and classroom demonstrations. Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology. Ajax Scientific distributes scientific equipment, supplies, and instruments for industrial, research, and educational applications. The company, founded in 1984, is headquartered in Toronto, ON, Canada.

EISCO Ray Box(1) Ray box, (2) meter of flex, (2) 4mm plugs, (1) 12V - 24W B15 bulb, (1) bulb holder, (1) slit plate, (2) aluminium blanking platesThis traditional Ray box has three openings, two of which can be used simultaneously by two sets of pupils. The two side openings each havetwo slots for accommodating blanking plates, 50 mm slide accessories. A front opening provides seven grooves for accessories and lenses which have been designed so that when used with a biconvex cylindrical lens of 75 mm focal length, divergent or convergent rays are obtained through the slit plate. Only a minimum of accessories are needed to cover a wide range of optics experiments. Supplied with 2 meter of flex and two 4mm plugs, 12V, 24W B15 bulb, bulb holder, slit plate, aluminium blanking plates. Supplied with working instructions.
