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 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.
Malus’s Law
Malus’s LawStudents can investigate the relationship between the proportion of transmitted light and the angle of rotation of two polarising filters. A graduated cartridge containing two polarising filters allows students to observe the change in intensity as they are rotated relative to one another.
Microwave Mounting Stand
Microwave Mounting StandHolds the receiver/amplifier and other objects for the Microwave Optics systems (WA-9314B, WA-9316).
Optics Bench Pair
Optics Bench PairThis is an economical alternative to a mounted optical bench. Each of the acrylic components can be easily aligned against a metre rule (not supplied) so that distances between components can be easily calculated and investigations into magnification and focal length can be carried out.
Optics Board
Optics Board9mm fibre board bonded to an MDF backing sheet for optics work. The fibre board takes optical pins for ray tracing etc.
Optics screen
Optics screenA 120 x 175mm white screen on a simple base for use in lens investigations where a real image is projected onto a screen.
Periscopes Kit
Periscopes KitA pack of 30 cardboard periscope nets with mirrors. Requires double sided tape for fixing the mirrors in place and normal tape for securing the net.
Polarimeter
PolarimeterPolarimetry is a rewarding field of study in any Post-16 course to explore the applications of polarised light.
Polarising Filter, 20 x 25cm
Polarising Filter, 20 x 25cmQuality filter that closes completely when placed 90 degrees above each other. (transmit below 0.005% with crossed filters).
Polaroid Analyser
Polaroid AnalyserThe Polaroid analyser gives a convenient method for analysing polarisation of light and stress in suitable materials.
Semi circular Refraction Dish
Semi circular Refraction DishThis open prism can be used in optics experiments to identify the refractive index of different liquids, as the exit angle in relation to the plumb line for the light source can be read at the bottom of the prism.
Note The material is plastic and is therefore not resistant to alkaline or acidic liquids, and it is therefore recommended that the prism be cleaned after use.
Slide Carrier
Slide CarrierA simple acrylic carrier to hold standard slides 50 x 50 x 2mm such as Young’s slits
Product code: LA20-882
Spare Tube For Polarimeter
Spare Tube For PolarimeterA flat bottomed glass tube of the type used in the Student Polarimeter
Spectral Source
Spectral SourceThis unique unit has been specially developed to provide a varied range of light sources for examination by spectrometers.
Speed of Light
Speed of LightVery short but powerful pulses of light are emitted from the box. When the light pulses hit the special retroflective foil of the reflector they are directed back towards the source – with no need for tedious adjustments. Via a beamsplitter, the light pulses finally hit a high speed photodiode, converting them into electric pulses to be displayed on an oscilloscope. A separate synchronization signal marks the time of pulse emission and constitutes a reference for timing the pulses.
Stress Structure Set
Stress Structure SetA set of four additional shapes for use with the polaroid analyser and a sheet of material 200 × 200 × 2mm from which other shapes may be cut.
