Our Products
Spectrometer is an instrument used to study the spectra of a material as well as to find its refractive index also. This is done by producing spectral lines and after that, wavelengths and intesities can be measured.
Sigma Spectrometers stand on top when it comes to quality, accuracy and workmanship. Our Spectrometers are exclusively provided with a buil in light system to read the Vernier scale. The light system in our Spectrometers is unique in its class and adequate in terms of illumination, enabling the user to read the Vernier scale easily. Our Spectrometers are checked tested and aligned in such a way that the optic axis of collimator and telescopes pass through the vertical line in the center of the prism table through the same point at all positions of the telescope.
lb photometer is used to compare the intensities of two light sources. This is achieved by using a combination of specially made prisms knows as lummer brodhun cube. Lb photometer consists of a box that is made totally dark from inside and the prism cube is fitted inside this box along with right angled prisms in a very symetrical fashion.
light entering from the openings of the box strike the right angled prisms and passes through a right angle and falls on the prism cube.
our lb photometer is best in its class and precisely developed. We use custom made right angled glass prisms whose opposite sides are made convex by grinding and then pressing against eachother in a special brass enclosure known as the brodhun cube. With precise, carefull machining and proper design, our lb photometer is totally capable of performing the light intensity experiments very accurately.
