3.5 Adjusting the Pathlength Selector
The pathlength of the Spex NanoSNAP is not automatically selected but selected manually. The metal light
path selector shown down below in Table 5 is the manual pathlength selector of the Spex NanoSNAP. The
measurement range of 0.5 mm pathlength is 0.04 to 30 Abs, and the range of 0.05 mm is 20 to 400 Abs.
Before starting to examine your samples, check if the light pathlength selector is in the right position. When
the pathlength selector is in the horizontal position to the detection arm (Figure 7), it represents the 0.5 mm
pathlength. In the vertical position (Figure 8), it represents the 0.05 mm pathlength. Hold the handle of the light
path selector to adjust between 0.5 mm and 0.05 mm pathlength.
