Battery Laser Ray Box
The Battery Laser Ray Box has many advantages over a standard ray box. These include:
Battery Laser Ray Box £25.00 Battery/mains Laser Ray Box d The Mains Laser Ray Box has many advantages over a standard ray box. These include:
Battery/mains Laser Ray Box £33.00 Colour Mixing Apparatus
The unit uses coloured LEDs to project primary and secondary colour mixing circles. Comes complete with primary and secondary shadow masks and colour TV demo. Supplied with plug top low voltage power supply. Please note. This equipment produces small colour mixing circles and is intended for pupil use. For demonstration apparatus please refer to the New Products section. Colour Mixing Apparatus £31.50
White Light Apparatus
A versatile teaching aid containing a white led light source at one end and a combined red, green and blue led at the other end. The RGB led is fully adjustable so that colour mixing may be demonstrated or red, green or blue light may be produced. Supplied with plug top low voltage power supply. White Light Box £31.50 Portable, Battery Operated UV Source
A battery operated ultra violet light source suitable for Forensic Science investigations. Takes 4 x AA cell (not supplied). Fitted with 150mm UV fluorescent tube.
Portable UV Source £9.99
Mains Powered UV Source
A mains operated Ultra Violet light source ideally suited to demonstration use. Comes complete with on/off switch. The tube is 45cm long and is housed in a UV reflective plastic housing. Suitable for showing the fluorescing properties of chemicals (eg washing powder) and for work in the new Forensic Science part of the syllabus. UV lantern £25.00 Replacement UV Tube £9.99 Audio Signal Generator
A microprocessor controlled signal generator, offering high quality output of sine, square, triangle and sawtooth waveforms. Output frequency is adjustable from 1Hz to 35KHz. Fixed output level capable of driving 1W into 8 ohms. Ideal for demonstration with an oscilloscope. Comes complete with plug-top power supply.Signal Generator £85.00
A compact loudspeaker unit fitted with a 10 watt, 8 ohm driver. Connection is via colour coded 4mm sockets. Fitted into a durable ABS case. Loudspeaker Unit £23.00
A superb class 2 laser pointer giving a bright red spot suitable for demonstrating and lecturing. May also be used with our diffraction gratings (above). The unit uses 2 x AAA cells (supplied). Red Laser Pointer £15.00
| Standard Ray Box 12V £27.00 24V £28.00
A robust ray box made from powder coated steel. Complete with a single/triple ray comb. The ray box is supplied with 1m of cable terminated with 4mm plugs. The ray box is supplied in two versions: 12V 21W or 24V 21W. Budget Ray Box 12V £21.00 24V £22.00
A robust powder coated steel ray box with two integral triple ray slits and one single slit allowing up to three groups to work simultaneously. Supplied with 1m of cable terminated with 4mm plugs. The ray box is supplied in two versions: 12V 21W or 24V 21W. Raymond the Raybox £15.00 Spare lamp £0.20
Specifically designed for Primary and Lower Secondary use, Raymond the Raybox has triple and single slits built in. In addition, three primary colour filters are fitted to allow the standard colour mixing discs to be easily produced with the aid of two plane mirrors (supplied). Raymond is operated from any 6V supply (batteries or power supply) and is fitted with 1m of cable terminated with 4mm plugs. Raymond is supplied with a spare lamp. NB Parallel light may be obtained using the 75mm cylindrical plano convex lens detailed below. Laser Element Class II £10.00
The heart of any laser is the lasing element. The element requires 3V dc which can be sourced from two AA/AAA cells. Enables the hobbyist to construct a class II laser at a very competitive price. Class II lasers are inherently safe as they have a power of less than 1mW and have zero infra-red content. They are the only type of laser approved for use in schools. Diffraction Gratings and Polarisers A range of diffraction gratings for general use or use with our range of lasers. Suitable for wavelength measurements.
Triple Grating (100l/mm, 300l/mm, 600l/mm) £19.00 Quality British grating - not to be confused with inferior Indian products. 500l/mm grating fitted in 35mm slide mount £3.95 1000l/mm grating fitted in 35mm slide mount £3.95 Polarising filter fitted in 35mm slide mount £3.95 Polarising Glasses two filters at right angles £1.00 Diffraction Grating glasses £1.00 Ray Box Spares Parallel light may be obtained from any of our ray boxes by using a cylindrical convex or biconvex lens of focal length 75mm.
*These lamps are suitable for Griffin, Philip Harris and older type ray boxes. They are not suitable for our ray boxes which are designed to take a radial filament lamp which is orientated to align the filament with the slits for the tightest possible beam. (Per pack of 10) 12V 5W SBC radial filament lamp £7.00 12V 12W SBC opal lamp £18.00 12V 21W SBC radial filament lamp £6.00 12V 24W SBC axial filament lamp £15.00 12V 36W SBC axial filament lamp £15.00 12V 48W SBC axial filament lamp £18.00 Brass SBC Lampholder £25.00
A brass SBC lamp holder mounted on a metal base fitted with 4mm sockets. Complete with lamp. Lamp holder only (no lamp) £4.20 Lamp holder + 12V 21W lamp radial £4.65 Lamp holder + 12V 24W lamp axial £5.25 Lamp holder + 12V 36W lamp axial £5.25 Lamp holder + 12V 48W lamp axial £6.00
