Description Measures transmittance or absorbance of visible light at three wavelengths through a sample with a 10mm path length and displays the values on a liquid crystal display or via USB to dedica
The Irwin Colour Mixing kit is designed to demonstrate primary and secondary colour mixing. The kit comprises, essentially, a scaled up version of our small colour mixing apparatus. A robust, upright
Aluminium construction with 9 black-light LEDs. Can be used to indicate gas leaks, tracking powder, counterfeit banknotes and pet stains. 30 lumen output. Requires 3 x AAA batteries. Length 90mm.
Metal-bodied solder sucker for removal of excess solder. Overall length 185mm..
Suitable for fine electronic work with heat-sensitive electronic components. Ideal for working on modern, low voltage circuit boards, fine wires and cables. Supplied with precision point tip. Temperat
This system provides a cost effective and simple to use light gate and millisecond timer for use with linear air tracks and measuring 'G by Free Fall' Each light gate has 4 threaded holes in various h
Clear acrylic all faces polished 100x18mm
S.B.C. double contact brass, lamp holder mounted on rectangular moulded base, with two 4mm socket connections.
A digital timer with multi functions. It can be used with photo gates to observe the frequency, time interval and as counter during the various experiments. It is a compact handy device operates on po
Periscope that allows the view of an obstructed field above or below the level of viewer. It is a Z shaped tube with mounted mirrors on both sides at 45° facing each other.
A set of acrylic blocks with white matt bottom to provide a view of the ray inside the block set in includes Semi circular block, Right angled prism, Trapezoidal block, Plano concave and Plano convex
The colour mixing apparatus consists of three super bright LED‚Äôs RED, \nGREEN and BLUE to demonstrate the creation of secondary colour with \na combination of three primary colors. Intensity of these three LED‚Ä&ocir
Reads to 6 minutes of arc (0.1°) 170 mm diameter metal scale graduated 360° x 1°, independently rotatable, with locking screw, vernier attached to the telescope reads to 0.1° (6 minutes of arc). Collimat
Pocket type magnifier mounted in single body with a metal cover which doubles as a handle fitted with a single lens of diameter 18 mm with a magnification of x 10.
The performance of this ultra-low cost spectroscope is comparable with instruments typically costing much more. It uses a CD or DVD as a reflective diffraction grating and clearly shows Fraunhofer lines in the spectrum arising from natural light
Laser Ray Box 5 Beams. Side by side lasers,1.6cm apart, 650 nm wavelength. Will easily demonstrate the following when used with suitable optics. Light bending by reflection, focusing effect, reflection with mirrors, Fre
Can be used to filter light sources for special effects and in scientific experiments. Supplied in pack of 5 assorted colours. Each piece 100 x 140mm approx.
These low cost solar beads (UV beads) are extremely sensitive to natural light and change colour dramatically from white to various colours when taken outside ‚Äö√Ñ√∂‚àö√ë‚
This meter is used to measure solar power (sunlight). It is an easy to use instrument which offers a compact design & robust construction. It is designed for environmental monitoring of sunlight intensity and is particularly useful to solar po

Spherical, optically worked glass, with grounded edges highly polished.
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
Resistance varies with the intensity of light falling on the unit.
Semi-circular concave mirror, 115mm x 50mm high. Depth is 75mm Made in stainless steel and polished on inside surface.
With ground and polished faces and ground edges. One each of double convex, plano-convex, \nconverging concave-convex, diverging concave-convex, double concave, plano-concave. Supplied in box.
Single moulded leak proof semicircular acrylic tank to perform a variety of light experiments and to find out the refractive index of different liquids. A protractor for measuring the angle of refraction with a circular scale
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
