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
Compact in size, inexpensive, lightweight with low power consumption diode laser is housed in a plastic moulded case (90x90x42) mm approx., qualitatively used for ray optics demonstration and simple diffraction work as well as to indicate the points on overhead images and charts. It required three button cells to project visible red spot with a sharply focused beam of wavelength (630-680) nm with only 1mw power consumption.
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.
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.
Fresnel Biprism setup illustrates about the phenomenon of interference of light. With the help of interference phenomenon, we can find the wavelength of monochromac light source like sodium light in a very easy manner. Complete with opcal bench of one meter long with 5 riders & Bi-prism assembly and Fresnel Bi-prism . Supplied without sodium light source.
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
