Title:
MALDI ION SOURCE
Document Type and Number:
WIPO Patent Application WO/2019/187353
Kind Code:
A1
Abstract:
This MALDI ion source 1 has a lens 6 that is provided between a mirror 7 and a sample on a sample plate 111. In the MALDI ion source 1, the optical axis of a laser beam coming into a chamber 3 from a laser light source 2 is located coaxially with the optical axis of light that is directed toward a camera 4 from the sample irradiated with the laser beam. Additionally, in the MALDI ion source 1, the lens 6 is used as a lens to collect light from the laser light source 2 and also as a lens for the camera 4. With this configuration, it is possible to reduce the number of components in the MALDI ion source 1. Furthermore, since there is no need to provide a lens between the laser light source 2 and the mirror 7, the distance between the laser light source 2 and the mirror 7 can be shortened. Thereby, it is possible to achieve downsizing of the MALDI ion source 1.
