The box is rectangular in shape and provided with slits on three sides equally spaced to enable three experiments to be performed simultaneously using one light source. Each slit is provided with a cover so that it can be closed when not required. Bulb holders of finest quality are fitted in wooden box with special co
Help your students to understand the properes of light energy with this kit. 18 acvities, including light transmission, light theory and color, light sources, reflecon, refracon and diffracon of light. Teacher's Guide included.
A very efficient 12 V 100W quartz iodine lamp mounted in a well ventilated metal housing. Apertures 19 mm diameter are provided on two adjacent sides so that the lamp may be used either as an intense horizontal 'line' source, or end-on as a powerful 'point' source. The aperture not in use may be closed by a pivoted shuer equipped with a lock screw. The lamp house is mounted on a rod 160mm longx10mm diameter for supporng from an ordinary laboratory stand. Dimensions of lamp house 78x78x153mm. Supplied complete with 1mmowin cable
Demonstrates the working and optical arrangement of simple optical instruments. Complete with lenses, mounted vertically on the board with a ray diagram printed to give an idea of their work. Different models available are
A solid state laser enclosed in a sheet metal case, produces a laser light beam of bandwidth 630 to 680 nm. Provided with clips on the output window for mounting of opcal accessories, as needed. Maximum output is rated at <1mW. With 3-core mains lead and ON/OFF switch and fused input.
A simple optical toy in a tube that produces beautiful symmetrical patterns due to reflection/refraction of light from numerous small colored glass pieces.
LO-6403Â Kaleidoscope, in plastic tube
LO-6403Â Kaleidoscope, in plated metal tube
Two transparent acrylic plates (90x90)mm and (90x120)mm printed with pattern of concentric circles to represent wave fronts and to demonstrate the interference pattern of two waves on an overhead projector.
Sheet Metal box with 12V, 10W Festoon type axially straight filament lamp. The body is fitted with a cartridge for holding 4 types of slits - single, double, triple and wide slots for quick adjustment to get the desired ray/beam type and with colour filters. Also included is a convex cylindrical collimating lens for adjusting the beam type to obtain long clear tracks parallel, converging or diverging in nature
LO-6367 Ray Opcs and Colour Mixing Box
LO-6367 Light Pipe or Light Path Guide Demonstrator for demonstrating the principles of fiber opc i.e., to confine light within a guide or fiber due to total internal reflecon. A ray of light directed into its one end will be emitted out at the other end with superb display of internal reflection. Boom frosted or painted white to aid the visibility of path followed by the light ray

Advance spectrometer with an improvement that the telescope and collimator are held in support rigidly and in perfect alignment. Vertical adjusting screws are provided to both the telescope and collimator. Clamping devices are provided to lock the telescope and collimator are adjustment i.e. fine adjustment to the telescope & collimator tubes are provided laterally as well as vertically
Our Advance Student Spectrometer is a solidly - the constructed instrument, thoughtfully provided with features and accessories that assist student sin making precise measurement of spectral lines or prism angle.� High Quality, large-aperture optics produce sharp spectral images, while precision machining allows for precise rotation and accurate measurement. Resolution to1minuteof an Arc.� The 125mm or 150mm diameter, precision engraved degree plate is complemented by 2 precision engraved verniers, one on each side of the instrument for convenient reading.

A diffraction grating spectroscope for viewing visible lines and absorption spectra. The spectrum is visible, superimposed on a scale, which gives the approximate wavelengths. The high-resolution diffraction grating replica used produces an extremely bright spectrum. The complete body of unbreakable molded plastic and can easily be held in the hand. The construction eliminates internal reflections to provide the sharpest, clearest spectrum possible.
This apparatus consists of two identical units, each provided with Polaroid disc mounted in a rotatable mount, with aperture of 25mm. Both rotatable mounts have a lever to add rotaon and a pointer which traverses a 75mmdiameter brass silvered scale divided into 360 1. The size is universal and can be fied to any size of collimator and telescope. To fit over the object end of telescope and colimator.
A compact visible spectrometer which allows the direct reading of spectral length and employs a prism for dispersion. It is also useful for flame test of basic radicals (sodium, stronum, potassium, copper etc.) There is a single eyepiece and independent focussing tube for the gracule, which carries an index at 590mm, with Dâ?? marked right below the scale, (corresponding to the wave length of sodium light) can be calibrated to a known light source by adjustment of knurled screw. The amount of light admited to the spectroscope can be regulated by a variable slit, adjusted by a knurled ring round the rating tube.
