Spectrometer - Advanced Manufacturer,Supplier and Exporter in India
Product Code : EL-W-11185
Product Description
The Spectrometer is an incredibly important and powerful scientific instrument, as it allows analysis of the composition of matter and the structure of atoms, just from the light emitted or absorbed by it.
A spectrometer has applications in many areas of science, including astronomy and analytical chemistry.
When combined with a Spectrum Lamp, Spectrometers provide an accessible way to teach this essential area of Physics.
The principle is simple; incident light is bent, or refracted, through an optical device such as a prism or diffraction grating.
A spectrum is produced, each wavelength of light refracted by a unique angle.
By measuring the angles at which light is refracted, a precise spectrum can be determined.
By looking at what spectral lines are missing, otherwise known as an absorption spectrum, the composition of a body that does not emit its own light, such as a gas cloud, can be determined.
Scale:
The 177mm diameter circle is fixed, and the table and telescope movements are completely independent of each other.
Both movements can be read to 30 sec. of arc by means of bouble ended verniers.
Both rotations have fine adjustment screws, and release of a clamping screw enables coarse adjustment to be made by hand.
Prism Table:
The table is marked with lines to assist placing the prism with respect to the table levelling screws, and has interchangeable clamping units for the prism and a diffraction grating.
Collimator:
Mounted on fixed pillar and fitted with 178mm focus achromatic objective, 32mm clear aperture. A unilaterally adjustable slit, 6mm long is also fitted.
Telescope: Mounted on moveable pillar and fitted with 178mm focus achromatic objective, 32mm clear aperture. Also fitted is a x15 Ramsden eyepiece and a cross line graticule.
Both the telescope and the collimator have rack and pinion focusing.
Standard accessories supplied:-
1 x diffraction grating holder.
1 x Watchmaker's eyeglass.
1 x dense flint glass prism.
1 x prism clamp.
1 x tommy bar for adjusting optical axes.
1 x Polished hardwood case.
