Colour Mixer
Colour MixerThis is a fully self-contained apparatus for demonstrating the mixing of coloured lights to produce secondary colours (and white) in the traditional three-circle pattern.
Colour Wheel
Colour WheelThe spinner is motorised and in use the apparatus is held in a clamp stand and the motor is connected to a variable low voltage d.c. power supply covering the range 0 to 12V.
Dual Colour Laser
Dual Colour LaserThe Lascells semiconductor laser contains two independently controlled laser diodes, one at the standard 650nm red and a second at 532nm green. Both lasers may be simultaneously passed through a double slit slide and both diffraction patterns may be displayed one above the other for an immediate comparison.
Emitter Detector Pair
Emitter Detector PairAn economical infra-red fibre-optic system providing and LED source and photodiode detector with housings to accept polymer fibre.
Fibre Optic Probe
Fibre Optic ProbeA white LED source with detachable fibre optic cable. The LED can be powered by any low voltage supply and when the fibre optic is inserted the beam can be seen coming from the fibre.
Fibre Optics
Fibre OpticsThis set provides a rugged, self-contained system for demonstrating and using a fibre optic communications link.
Fibre Optics Polymer 20mtrs
Fibre Optics Polymer 20mtrs20m of unterminated fibre optics polymer.
Fibre Optics Polymer 5mtrs
Fibre Optics Polymer 5mtrs5m of unterminated fibre optics polymer.
Infra Red System
Infra Red SystemThis equipment is designed to support the topic of the Electromagnetic Spectrum so that a practical demonstration of the application of infra-red radiation can be given.
Laser Receiver
Laser ReceiverA dual purpose receiver designed for use with the Lascells Dual Colour laser, the unit contains a planar chip photodiode tied to a 1Mhz amplifier for speed of light calculations along with an audio amplifier for demonstrating data transmission using light.
LED Light Source
LED Light SourceThis apparatus has been updated to simplify the construction and provide improved performance at reduced cost.
LED Ray Box
LED Ray BoxA classic ray box for ray tracing in optics experiments. The light source is a high intensity white LED which runs at low temperature. Ships with removable slit plate and lens to provide one or three parallel rays.
