One of the most troublesome problems in LIF experiments currently being performed in our laboratory to expand the spectral database on species relevant to propellant combustion is the appearance of unwanted, scattered laser light at the detector. This problem can severely reduce the overall sensitivity of the system preclude experiments. One way to largely alleviate the problem is through the use of light baffles as designed by J.E. Butler of the Naval Research Laboratories. However, the design of mounts for these batteries is not a simple matter because of several problems including alignment of multiple baffles through which the laser beam must pass and fragility of the baffles. This report presents a simple mount which we have designed to overcome all of these problems. The mount is easy to make, may be stacked if multiple baffles are desired, and protects the baffles from damage while removed from the vacuum system. |
