Optics | Light, Sound and Waves | PHYSICS A. Camera Obscura
The ancestor of all cameras, this hand-held camera obscura projects an image onto a screen inside the box.
The wooden camera is supplied in kit form and has an authentic look and feel when assembled.
E8R07413 B. Ray Optics Kit
A versatile kit of components for ray optics experiments. Possible investigations include linear propagation of light rays, focusing of rays by cylindrical lenses, focusing of multiple rays showing aberration, law of reflection, refraction in water, prisms, etc.
Contents: • 2 lamps and stands • 1 pair of housing shields • 2 combined single and triple slit plates • 2 multiple slit combs • 2 holders for combs and slit plates • 4 wooden light barriers • 4 plano cylindrical lenses +7D • 2 plano cylindrical lenses +10D • 2 plano cylindrical lenses +17D • 2 plano cylindrical lenses -17D E8H25857
C. Lamp and Stand
Comprising a 12V 24W lamp in a conical lamphouse mounted on an adjustable boss. The lamphouse has cut-outs in its side giving a clear passage for the light while restricting the amount of stray illumination. The assembly is supported on a rod with a triangular cast base. Triangular base: 100mm side x 28mm high. Overall height of stand: 240mm. Supplied with lamp and lead with 4mm plugs.
E8H76828 D. RayZer Lightbox
Bring modern technology into your classroom with this raybox for the 21st century.
This unit is for studying ray optics. It contains 3 laser diode modules. The power of each diode is less than 1mW and the wavelength is 650nm.
The Rayzer is supplied with a plugtop power supply and is mounted on a white plastic baseboard. The beams may be switched between one and three.
Paper can be placed on top of the baseboard and the rays traced. If required the unit can be used with a 9V PP3 type battery and our battery connector.
Classroom management is eased as no blackout is required to operate the RayZer.
When the RayZer is switched to one beam and a diffraction grating is placed in the path of the beam the wavelength of the laser light can be calculated.
The RayZer has been tested for safety and it is class 2 to the current versions of IEC 60825-1 and BS EN 60825-1.
