Tech Note 673 Detail

Mercury lines are difficult to obtain.

Affected Products:

SE-9466 Spectral Tube (Mercury)
PS-2176 PASPORT High Sensitivity Light Sensor

Problem/Symptom:
Mercury lines are difficult to obtain.

PASCO Solution:
  1. Because the PS-2176 has continuously variable oversampling, decreasing the sampling rate and scanning the spectrum more slowly increases the signal-to-noise ratio as the square root of the inverse of the sampling rate.
  2. Use a brighter mercury light source, such as the SF-9288 Osram Lamp Power Supply and Mount to obtain a better signal without modifying the sampling rate.

Note: You can get a quick spectrum even in low light by using the Ocean Optics spectrometer system.
