Light
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.
Photo Detector
Photo DetectorEnclosed in a robust case this broad sensitivity detector provides a simple solution to showing that the electro-magnetic spectrum extends either side of the visible.
Pin Hole Camera
Pin Hole CameraFor student investigation of basic image production. Each “camera” is constructed from a durable, black ABS tube 190mm long and 50×60 end section which can stand repeated use and storage while leaving the students scope to construct the rest of the system.
Plane Mirror [Set Of 10]
Plane Mirror [Set Of 10]A pack of ten rear surface glass mirrors with ground edges for general optics work.
Polarimeter
PolarimeterPolarimetry is a rewarding field of study in any Post-16 course to explore the applications of polarised light.
Polaroid Squares
Polaroid SquaresA pair of rigid plastic Polaroid squares measuring 50 × 50mm each for use in polarized light investigations.
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
Solar Cell Array
Solar Cell ArrayThis unit measures 200 × 70 × 60mm and houses four solar cells, each 50 × 30mm. The cells are connected to 4mm sockets along either side of the base so that they may be connected together in any combination.
Two screw terminals are provided for connecting load resistors etc.
Solar Cell Investigation
Solar Cell InvestigationThis apparatus has a solar cell mounted on an acrylic base with moveable covers. Students can investigate the output of the cell as different areas are exposed to light making for an excellent investigation at KS3/4 combining electrical measurement with alternative energy topics.
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.
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.
