OPTICAL BENCH FOR LASER DESORPTION/IONIZATION MASS SPECTROMETRY

摘要

A laser optical bench for use with a laser desorption/ionization mass spectrometer. The laser optical bench includes a laser for producing light, a focusing structure that receives light from the laser and focuses predominantly in a single plane, an attenuator that receives light from the focusing structure, beam steering structure for directing light from the attenuator from the target; and a final focusing element for focusing light from the beam steering structure on the target. Further focusing elements may be included for further focusing and dispersing the light beam in different planes. Additionally, photodetectors or photodiodes may be included for energy measurement and sensing a lasing event.
