Product Code :- CLM/PHY/LO-0122

Description:
• This spectroscope is a self-contained device for separating the optical light components from a light source and for measuring their wavelength in nanometers. The instrument is hand held and is directed to the source of the light. The viewing hole carries a diffraction grating which behaves as a prism and causes the light source to deflect on its way to the viewer’s eye. A scale is mounted inside the box and this allows the amount of deflection to be measured and this deflection is calibrated as wavelength in nanometers. The various different components of colour that make up the original light source are easily seen as colour bands at various wavelengths. A scale is printed on the box with spectral scales of different light sources /Spectral lamps.

Product Code :- CLM/PHY/LO-0128

Description:
• Used as a Sodium vapour light source. These are 2mm and 4mm holes, 4mm x 20mm vertical slit. The lamp power supply housing provides two intensities of operation. The lower intensity provides the more pure sodium vapour performance because the gas in the lamp runs cooler and is a more predominantly monochromatic sodium source. Using a spectroscope, the sodium ‘doublet’ is clearly visible and this lamp is suitable for general purpose monochromatic work in the classroom when used at the low power setting. The high power setting is useful to demonstrate the change in overall colour as the various other wavelengths begin to appear. Operating voltage 220/240V.AC. 50 Hz.
