An interferometer is a measuring device that helps in measuring rough surface profiles on a test object. The measurement is performed using radiation that is coherent over a short distance, a reference beam being periodically modulated in its path of light within propagation time. They are made to interfere with a measuring beam reflected off of the surface of the test object, and the interfered radiation being evaluated with respect to the maximum of the interference contrast. With a simple design, a high measuring accuracy is achieved in that the measuring device has a modulation-interferometer arrangement MI, in which the path of light is altered using acousto optical deflectors. A compensation device is provided for correcting the spatial decoherence and dispersion. In a downstream demodulation-interferometer arrangement, the measuring beam is interfered by the reference beam and fed to a photo detector.

We are a trusted names in manufacturing sodium lamps which are a kind of gas discharge lamp which uses sodium in an excited state to produce light. There are two varieties of such lamps:

• Low pressure:


The Low Pressure Sodium (LPS) Lamps, also known as Sodium oxide (SOX) Lamps, consist of an outer vacuum envelope of glass coated with an infrared reflecting layer of indium tin oxide, a semiconductor material that allows the visible light wavelengths out and keeps the infrared (heat) back.

It even has two inner borosilicate glass U-pipes that hold solid sodium and a small amount of neon and argon gas Penning mixture to start the gas discharge, so when the lamp is turned on it emits a dim red/pink light to warm the sodium metal and within a few minutes it turns into the common bright yellow color as the sodium metal vaporizes.


• High pressure:


The another kind is High pressure sodium (HPS) lamps which are smaller and contain additional elements such as mercury, and produce a dark pink glow when first struck, and a pinkish orange light when warmed. Some bulbs also briefly produce a pure to bluish white light in between. This is from the mercury glowing before the sodium is completely warmed.

The sodium D-line is the main source of light from the HPS lamp, and it is extremely pressure broadened by the high sodium pressures in the lamp, so colors of objects under them can be easily identified.

Our spectrometer consists of a graduated circle, generally fixed in a horizontal position, to which is attached a collimator and a telescope. Its collimator consists of a tube containing an achromatic lens at one end and a vertical slit at the principal focus of the lens. The movable arm carries an astronomical telescope which is always directed towards the center of the graduated circle.

The position of the telescope with reference to the fixed circle can be read by means of a vernier. Above the center of the graduated circle is a horizontal table, called the table of the spectrometer, which is capable of rotation about the vertical axis of the circle. The position of the circle table can be determined by means of the vernier.
