UV/VIS Array Spectrophotometers without Deuterium Lamp

Fewer Lamp Replacements and Fast Measurements are important topics. Read the white paper “Array versus Scanning” you can find a detailed experimental comparison of both well-established spectrophotometer setups. Learn the benefits and advantages of UV/VIS Array Spectrophotometers without Deuterium Lamp.

UV/VIS spectrophotometers can be classified according to the geometry of the components that build up the optical system. There are two types of configurations used in UV/VIS spectroscopy:

  • Scanning spectrophotometer, usually equipped with a deuterium lamp
  • Array spectrophotometer, usually equipped with a xenon lamp

Performance aspects of a UV/VIS spectrophotometer such as optical and wavelength resolution, measurement speed, bench space requirements, cost of ownership, and many more, depend directly on the design of the instrument.

Xenon versus Tungsten Deuterium Lamp

Most of the currently available UV/VIS spectrophotometers are equipped with a combination of a tungsten and a deuterium lamp as the light source. This type of lamp must continue to operate during the entire instrument up-time. Xenon lamps exhibit a similar spectral distribution to sunlight. Only one lamp is thus required and it only needs to operate during the actual measurement. The Array Versus Scanning white paper compares the two well-established UV/VIS spectrophotometer setups and assesses their individual performance as well as that of the two different types of light sources.
