Paper that prints silhouettes with sunlight. Place an item on top of the Sun Print Paper and then place it in direct sunlight. Remove it again after a few minutes and dip the paper in water to instantly develop a silhouette of the it
A 250W tungsten filament bulb available with bayonet fitting, internally silvered.
A cluster of three LDR’s, connected in parallel, to provide increased \nsensitivity and better control of current directly in a reed relay.
This meter is a precision instrument used to measure illuminance in the fi eld. It meets \nCIE photopic spectral response and is fully corrected for angular incidence of light. \nSupplied with carry case instruction manual and battery. Measuring r
Semi-circular convex mirror, 115mm x 50mm high. Depth is 75mm Made in stainless steel and polished on outside surface.
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
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
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 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
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
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
