1 System Description
Optical System
The optical system includes a xenon flash lamp, the monochromators, excitation
bandpass filters, emission cut-off filters, and a PMT detector.
There are a number of cables and fibers that exit the optics bench and enter the read
chamber. They are the excitation fiber (thin and black, has a collar and pins), emission
fiber (fatter, with attached electrical cord), electrical connector to the read head (black
with brass fitting).
Caution:
Optical fibers are very fragile, especially the excitation fiber. Handle cables with
extreme care. Do not flex, twist, bend, or stretch the optical cables.

Overview of Optical System
1
The excitation light source is a xenon-arc flash lamp. (Note that the lamp is off when
luminescence mode is selected.)
2
The light passes through a band-pass filter which reduces the amount of stray light to the
excitation monochromator.
3
The holographic diffraction grating monochromator selects the desired excitation
wavelength.
