  • A student instrument for simultaneously showing the spectra of two gas discharge spectrum tubes against a common back-lighted scale that reads in nanometres.
  • This unit may also be used to observe other light sources, such as halide, fluorescent and sodium vapour lamps.
  • It uses a fine grade replica transmission grating of 600 lines per mm to create a virtual image of the two spectra one above the other.
  • The scale, which is about 75mm in actual length, is illuminated only when the pushbutton at the end of the cord is held closed.
  • A long-life 9 volt alkaline battery is included.
  • Calibrations are from 380 to 760nm.
  • Strong spring wire clips hold the spectrum tubes securely.
  • The adjustable slit is controlled by the small knob on the side.
  • The cast aluminium housing is finished with light gray polyurethane paint.
  • The weight is well-balanced on the stainless steel post and wide-span tripod base.
