This system is easy-to-use and inexpensive, with a variety of safety features that make it suitable for beginning labs. Mount any of the 8 different spectral tubes into the power supply and turn it on. The 26cm long tubes a re capillary-thin over the middle 10 cm, providing sharp, bright spectra.
Features Student Safety:� The tubes mount from the front of the supply and snap into moulded sockets that fully enclose the conducve ends. The all metal case is electrically grounded.
Spectral Tube Safety: A c u r r e n t l i m i n g transformer protects the tubes. A protecve shield also helps safeguard the tubes, while blocking unwanted ambient light for clear viewing
Philips make Mercury Vapour Lamp is supplied. With a rated output of 80W, this source provides sufficient intensity for almost any experiment. With a good light source, student can invesgate energy levels using a spectrometers.
Either Philips or Osram make Sodium Vapour Lamp is supplied. This low pressure Sodium Vapour lamp works better than 99% of the visible output, concentrated in 5889 0 & 5895 A Spectra lines

It is Ramsden eye piece with a plain glass plate held between lens and eye lens at 0 an angle of 45 . This item replaces the normal spectrometer eye piece when aligning the instrument
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.
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.
Imported Laser tubes along with SMPS Power Supply are housed in thick powdered coated aluminium box. From the hole the laser beam comes out . Supplied with rectangular holder & heavybase
A compact, fully solid state instrument produces an intense beam of light at a wavelength 635-670nm for red colour. This semiconductor diode laser is mounted in a simple mount. Supplied completely with power supply
Generally this light source is used for above Michelson Interferometer. Supplied with sodium vapour lamp transformer 35 W, sodium vapour lamp 35W & heavy metal box for sodium vapour lamp with electrical fing
A simple device for the rapid qualitative examination of the composition of emission and absorption spectra. It has the principal components â?? collimator, prism, and telescope, all arranged along the same straight tube. Comprises a plated brass pipe with adjustable slit at one end for adjusting the inside amount of light entering inside, and a drawtube at the other end having eyepiece. The drawtube can be slid along its length for sharp focusing of the spectrum and is fitted with a multi-element prism causing appreciable dispersion of light without the device.
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.
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.
