It consists of a 1 1/2 meter long stainless steel double rod optical bench with the following accessories.Lamp house : an electric bulb workable on 220V AC is encased in a metal caseMetal Screen White with cross slit : the slit has one white surface and other black Plane true tiltable mounted mirrorLens assembly consisting of combination of single & double lens holder on a mount rotating on a vertical axis. The Assembly is adjustable in height and can be moved by rack & pinion.
Complete with 1.5 meter ss rod optical bench having the following components L.B. Photometer Head : made from precision optics. Light Form two sources fall on either side of a uniform white opaque screen and is reflected by side reflectors. Then it passes through LB cube. Observing the field through a telescope, tow light intensities are compared directly.Lamp House : tow lamp houses with electric bulbs workable on 220v.
Superior quality, all parts are made from brass, achromatic objective, provided with wooden folding stand.
For Accurate measurement of refractive index of transparent liquids, solids and solutions, used in sugar, ghee and oil mills, pharmaceuticals and chemicals chemical laboratories, jam factories and distilleries etc. Measuring range 1.3000 to 1.7000, measurement of sugar )% to 95%. The body of instrument is fixed with a leaning of 600, correct reading can be taken in the fields. It includes Abbe’s double prism with thermostat, compensator, telescope mirror, graduated scale, reading magnifier and radial arm which carries vernier. Complete in polished wooden box
With a rated output of 80 watt, this source provides sufficient intensity of white light for almost any experiment
Wooden box with slits on three sides to perform 3 experiments at a time, each slit has two riders to adjust the lenght of slit or close it when no experiment is being performed.Regular quality made of ordinary wood.Deluxe quality made of superior wood and has different sized slits for different experiments. The height of the box can also be adjusted to suit the requirements of the experiment
Simple form for school and junior colleges, focussing from one meter to infinity, provided with 10x Ramsden eye piece with cross wire, achromatic objective. Focussing with rack & pinion, height of telescopes is adjustable, fitted on cast iron base
Amounted on nice duco painted round cost iron heavy base with three levelling screws and 25mm dia and 450mm long steel pillar. The telescope is provided with high class optical combination and brass. C.P. fittings, provision for up and down, to and from moting is incorporated, complete with perspex scale and scale and scale holder.
For demonstration of interference, diffraction and holography. Laser source and switch mode power supply are housed in a thick aluminium box with a hole through which laser beam comes out. The laser unit is mounted on a precision 1 meter double rod SS optical bench. Intensity of laser beam is 2mW and it is red in color. Input power is 220V AC. Minimum operating life is 15,000 hrs. and shelf life is 10 year. The unit is supplied with single slit and diffraction gratingAlthough this is a very safe equipment to handle still a few precautions will ensure proper safety and long life viz. Operate the laser at least once in a fortnight
Workable on 230V AC, it gives stabilized power output of 2 amp. 12V DC, housed in sturdy metal box.
An ideal instruments to demonstrate basic principles of light like reflection, principles of light like reflection, refraction, deviation of light through prism or slab, with standard accessories
