Epoxy molded gas cell for optical measurement and method of forming

摘要

The present invention relates to a gas cell (1) for optical measurements of gas content and/or concentration comprising a cavity (1a), at least one aperture (11) for gas exchange, at least one first socket (12) for light emitting means (2) and at least one second socket (13) for light detecting means (3). The length of an optical measuring path (A) through the cavity (1a) is defined by a direct or indirect distance between a light emitting means (2) in the first socket (12) and a light detecting means (3) in the second socket (13). The present invention teaches that an epoxy mold compound is used to form at least the parts of the gas cell (1) that define the optical measuring path (A).

主权项

1. A gas cell for optical measurements of gas content or concentration in a macroscopic system wherein a length of an optical measuring path is in the range of centimeters, the gas cell comprising:
a cavity; at least one aperture for gas exchange; a plurality of sockets including a first socket for a light emitter and a second socket for a light detector; and an optical measuring path through the cavity, wherein a length of the optical measuring path is defined by a direct or indirect distance between the light emitter positioned in the first socket and the light detector positioned in the second socket, and wherein an epoxy mold compound is used to form at least the parts of the gas cell that form the length of the optical measuring path.
