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.
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
Interference fringes are clearly seen when the apparatus is viewed in sunlight, fluorescent light or monochromac light. The glass plate and convex lens are held in a heavy aluminum frame having three adjusng screws. The frame is 9 cm in diameter and aperture is 5 cm.
This aluminium metal box is round in shape & mounted horizontally on a sturdy metal base. Box is provided with one slit fitted with iris diaphragm to control the intensity of light. Bulb holders & lead of finest quality are fied in box to give you trouble free working for long life. This mount is suitable for 35W as well as 55W Lamp. Supplied without bulb & transformer.
An 80 Watt choke of excellent quality is clamped on a heavy steel cabinet. An Anchor make piano type switch ad 5-pin socket is provided for on/off and output respectively
The Iron sheet box is round in shape & mounted vertically on a heavy cast metal stand. Only one slit is provided. Bulb holders & lead of finest quality are fitted in box to give you trouble free working for long life. Suitable for 80W lamp. Supplied without lamp & choke.
Specially designed for easy to use, moderately priced, for colleges and research laboratories. Ideal for determining the specific rotaon of optically acve substances. Our Polarimeters are now extensively used in industrial laboratories as well. A corning glass tube is enclosed in a circular aluminum tube with top door for access and exclusion of external light. The circular scale is aached near the analyzer and the range of measurement is 0 360�°.A movable Vernier on the scale enables reading of optical rotation to 60 seconds. Worm and gears combine rough and fine adjustment, provided with , giving three parts field for easy seng, adjustable half shadow angles. This instrument can be used on monochromtiac light only. When light passes through a polarized sheet and then through the soluon, the emerging light is observed through rotatable polarized lens, analyzer which is used as eyepiece. The angle of lighs rotated and read directly on the circular scale. Supplied on the adjustment stand, Packed in cardboard box with working manual.
Laser Reflection and Refraction Tank demonstrates the principle of reflection and refraction. The clear circular acrylic tank has a circular scale graduated on the white base of the tank, making it easy to measure angles. Adjust the pivot-arm mounted laser to any angle along with its full 360�° range and measure the angle of reflection or refraction. Rotate the laser and observe first a reflected ray, then both a reflected and refracted ray, and finally just a refracted ray. Leveling screws on the tank's base make leveling quick and easy. The laser is attached to the pivot-arm by a magnet and can be removed for use in other experiments. Instructions 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.
