Spectrometers

 SPECTROSCOPE, DIRECT VISION

Spectroscope 

For quantitative examination of spectral composition of white light, radiant bodies etc.
Comprises a metal draw-out tube of 20mm diameter, with an adjustable slit at one end. The light passing through this slit falls on the prism elements and break up into a spectrum. This can be viewed through an eye piece at the other end of the tube. Fully drawn-out length is 130mm. Supplied in a velvet lined case.

Cat. No.

3372-00


SPECTROMETER, STUDENT

Spectrometer

For introducing students to principal type of spectra, determination of wavelength, frequency of emitted light and for quantitative spectrometric measurement of angle of prism, refractive index of the prism material etc.
Comprised of a cast base with an integral fixed pillar for the collimator support and a swinging telescopic arm. Both the collimator and the telescope are fitted with an axis adjustment system. 

The moving telescope arm with a spring loaded vernier moves smoothly over a machine engraved degree plate of diameter 180mm and is graduated 0-360 x 1.

The vernier reads to 0.1 or 6 seconds and allows students to estimate angular positions to 0.05. Fine adjustment is provided.
The collimator and the telescope tubes are fitted with optically coated achromatic objectives of diameter 25mm and have a concealed helical action focusing device. The 10X Ramsden eyepiece has a cross hair reticle.
The prism table, diameter 75mm is leveled by three knurled knobs. It is fitted with a diffraction grating holder of aperture 25 x 25mm and a clamp for holding a prism up to 38mm high. Lines are marked on the table to help place the prism accurately. Various parts are either plated or enamel finished.
Provided with a magnifying eye glass and a tommy bar for axis adjustment but without prism or diffraction grating. Supplied in a cardboard box.

 

 

Product Code: 3380-00


 SPECTROMETER, ADVANCED

Spectrometer 

Similar to 3380-00 but with enhanced features for obtaining better quantitative results. Consists of a heavy cast base and a pillar for collimator support. The telescope arm moves along a fixed circular plate 150mm diameter graduated in degrees. This plate has a double ended vernier for better and accurate measurements, with a least count of 30. Fine adjustment is accomplished by using a knob while the coarse adjustment can be done by hand. Both the collimator and the telescope are mounted with an axis adjustment system.

The telescope has a 10X Ramsden eyepiece and is fitted with a cross hair reticle. Both the telescope and the collimator are fitted with coated achromatic objectives of 178mm focal length and 32mm diameter, providing light for a brighter and sharper image. 

The focusing is done by a concealed rack and pinion. The collimator slit 6mm long, is specially designed for retention of initial accuracy during the life of the instrument.
The prism table 75mm diameter is held with the help of a clamping screw enabling the table to be rotated in any direction. It has lines and concentric rings marked to assist positioning of prism in relation to leveling screws. It is fitted with a diffraction grating holder of aperture 25mm x 25mm and a clamp for holding prisms up to 38mm high.
Provided with a magnifying eye glass to read the vernier, tommy bar for axis adjustment and flannel cloth. Supplied in a wooden box.
