Specification of Zeiss Opton Lamp for Model PQ4 Ultraviolet Spectrophotometer

Following are the detailed information of this instrument:

It is not uncommon for spectrophotometers to have different light sources (lamps) that are interchangeable. Different light sources (i.e., hydrogen, quartz, ultraviolet) each produce different types and intensities of light that can be used for specific experiments.

Spectrophotometers determine the composition of a solution (or the concentration of certain substances within a solution) by measuring how the solution absorbs a particular wavelength of light. By varying the wavelengths in each measurement, one can take a spectrum of a solution and ascertain the composition. More advanced spectrophotometers can measure beyond the visible spectrum, providing readings for ultraviolet and infrared wavelengths.
