An all metal ventilated lamp house having an open front with extended sides \nfinned externally for heat dissipation and vertical internal grooves to accommodate a slit plate. It has a light source comprising of a 12 volts lamp in a holder with on
A metal Ray Box comprises of a die cast enclosure, delivers white light but runs much cooler than conventional ray boxes. It uses the latest cool ultra bright LED technology giving superior white light. Supplied complete with slit plate and batter
Non-optically worked with polished faces, edges slightly beveled. Nominal angles 90 x 45 x 45. Size: 50mm
Non-optically worked with polished faces, edges slightly beveled. Nominal angles 60 x 60 x 60.
A set of brightly coloured hand magnifiers, ideal for investigating bugs, leaves and patterns in nature. 60mm dia lens with 3x magnification. Supports the following areas of learning: • Understanding
For use with the mounted solar cell or on its own. A12V, 24W S.B.C. bulb in a metal socket mounted on a base with pair of 4 mm sockets
For use with the motor to demonstrate the \nproduction of electrical energy directly from \nlight energy. The apparatus comprises a \nselenium photo-voltic cell.
Metal-bodied solder sucker for removal of excess solder. Overall length 185mm..
A ray box consisting of a rugged sheet metal box with a 12 V, 10 W festoon type axially straight filament lamp. Fitted with a cartridge for holding 4 types of slits – single, double, triple and wide slots Ideal for quick adjust
Cardboard kaleidoscope tube that creates pretty multi-coloured patterns with the mirrors inside. Cardboard kaleidoscope 17cm
A flat glass plate and a slightly convex lens of 50 mm diameter Are placed in a metal frame with three pressure adjusting screws to produce Newtons Rings.
For demonstrating that white light may be composed from all the spectral colours by rotation of the multi coloured disk. Comprising of a 200mm disc, and driven by gears with the help of driving wheel fitted with a handle can be clamped to a desk.
Evacuated glass tube, about 26cm long, straight \nform, filled with different types of gases or vapours \nto study their respective discharge. The glass tube \nhas metal cap electrodes at both the ends for \nconnecting to high voltage supply and a
For the rapid examination of spectral composition of white light, metal tube with draw out focusing and an adjustable slit fitted with a chromatic objective glass and 3 element prism. Complete in wooden box.
Housed in black metal body, specially molded spectrum tube sockets enable the tube to be placed in position easily and also provides protection against electrical contact. Bottom socket is spring loaded for easy tube
These pigments normally have a pale, off-white appearance but in sunlight or UV light they instantly change to a bright, vivid colour. The pigments revert to their pale colour when away from sunlight or UV light. If the pigment is mixed with a bin

This liquid is non-toxic liquid paraffin containing a UV sensitive photochromic dye. Indoors it appears as a clear liquid but when exposed to natural light it immediately becomes coloured. This colour increases in intensity when exposed to direct
A range of encapsulated solar cell modules mounted in sturdy black polycarbonate cases. The faceplate consists of tiny bubble magnifiers which maximise performance by enhancing light as it strikes the cell. Monocrystalline constructi
Non-RoHS Photoconductive cadmium sulphide cell with a spectral response similar to the human eye. As light falling on the cell increases, so the resistance of the cell decreases. Peak spectral response: Typ. 550 nm
A mains operated Ultra Violet light source ideally suited to demonstrate use. Comes complete with an on/off switch. The tube is 45cm long and is housed in a UV reflective plastic housing. Suitable for showing the fluorescing propert
Two photo gates which can be used as a light operated timing gates. Fitted with a pair of 4mm terminals to allow \nconnection to electronic timers. When the light gates are switched on it creates a short circuit, \nwhich becomes an open circuit ea
To explore light reflection and refraction properties of concave and convex mirrors, laws of reflection, image formation, the effects of surface curvature on reflection, spherical aberration etc. Each
Comprise 7 blocks in wooden storage box as follows: \nRectangle 75 x 50 mmlSemi Circular 75 mm dia. \nTriangle 60º x 60º x 60º, 58 mm side. \nTriangle 90º x 45º x 45º, 75 mm hypotenuse. \nTrian
Transmission type 50x50mm available 600 lines per cm. Mounted in plastic frame.
A 250W tungsten filament bulb available with screw fitting, internally silvered.
For use with the motor to demonstrate the \nproduction of electrical energy directly from \nlight energy. The apparatus comprises a \nselenium photo-voltic cell.
UT383 is a MiniLight Meter equipped with photo electricsensing technology, which can effectively represent light intensity with electrical signals, then processes data and displays the result on LCD. It is light weight, compac
