Optical Research Instruments

Constant Deviation Spectrograph

A Constant Deviation Spectrograph is widely used in advanced optical studies. The special quality of the prism used in the instrument is finely cut and optically worked to ensure that the angle of incident light and angle of emergent light is the same. High quality optics used in the construction ensure that accurate results are obtained with every use.

Photo Measuring Comparator

An optical comparator, this instrument is used to optically measure various objects to a high degree of accuracy. The instrument finds wide application in the manufacturing industry as it capable of measuring the smallest deviations from the benchmark.

Fabry-Perot Etalon

The Fabry-Perot Etalon is widely used in telecommunications, lasers and spectroscopy to control and measure the wavelengths of light. Given their wide application, students find it helpful to work with the instrument to develop a solid foundation. Our Etalon has been specifically designed for experimentation. It is easy to use and delivers accurate results and hence a favourite among educators.

Edser Butler Plate

The Edser-Butler plate is extremely helpful in determining the diameter of fine fibres. By analysing the interference pattern of light from two, parallel, semi-silvered surfaces, the diameter of the fibre can be calculated to a high degree of precision. The optical surfaces of our Edser-Butler Plate are precisely worked to give a clear interference pattern and hence makes it easy to use.

Fabry-Perot Interferometer

An instrument suitable for comparison of wavelengths of different light sources. The instrument is also widely used to study the hyperfine structure of spectral lines and Zeeman Effect by measuring the changes in wavelength of light on application of magnetic field. Given the use, it is evident that precision is the key, and our Fabry-Perot Interferometer is known for its accurate & consistent performance.

Michelson Interferometer

The Michelson Interferometer is used to accurately measure the wavelength of optical beams through the creation of interference patterns. The Michelson interferometer is a historically important & compact device which provides simple interferometric configuration. Our Michelson Interferometer has accurately machined fine motion and high quality optics makes it easy to use without compromising on the accuracy.
