Abstract
A gas sample vessel for a gas analyzer comprising a housing enclosing a cylindrical resonator cavity. Two mirrors which limit the resonator cavity are fastened to the housing for coupling in and feeding back the measurement light proceeding from an illumination source. The mirrors are curved concavely at their surfaces facing the housing and the housing is curved convexly at its surfaces facing the mirrors with approximately the same radius of curvature. The centers of curvature lie in the center axis of the resonator cavity and the mirror surfaces of the mirrors are portions of the concavely curved surfaces facing the housing.

A gas sample vessel for a gas analyzer comprising:
- a housing enclosing a cylindrical resonator cavity having a center axis;
- two mirrors which limit the resonator cavity being fastened to the housing for coupling in and feeding back the light proceeding from an illumination source;
- the surfaces facing the housing for said mirrors being curved concavely;
- the surfaces facing the mirrors for said housing being curved convexly with approximately the same radius of curvature;
- corresponding centers of curvature lying in the center axis of the cylindrical resonator cavity;
- and
- mirror surfaces of the mirrors being portions of the concavely curved surfaces facing the housing.
A gas sample vessel for a gas analyzer comprising:
- first and second mirrors each having a spherically curved concave surface;
- and
- a housing enclosing a cylindrical resonator cavity having a center axis, the housing having:
- a first end having a curved convex surface and facing the curved concave surface of the first mirror;
- and
