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.

L'invention concerne un banc optique laser qui s'utilise avec un spectromètre de masse par désorption/ionisation laser. Le banc optique laser inclut un laser qui émet de la lumière, une structure de focalisation qui reçoit la lumière du laser et focalise principalement sur un seul plan, un affaiblisseur qui reçoit la lumière de la structure de focalisation, une structure de pointage du faisceau qui oriente la lumière de l'affaiblisseur vers une cible, et un élément de focalisation terminal qui focalise la lumière de la structure de pointage du faisceau sur la cible. D'autres éléments de focalisation peuvent être inclus pour efectuer d'autres focalisations et disperser le faisceau lumineux sur différents plans. En outre, des photodétecteurs et des photodiodes peuvent être inclus pour mesurer l'énergie et détecter un événement de lasage.
