Abstract
A sample holder for spectroscopy is formed by pressing a wire mesh so that its thickness is reduced. Preferably the mesh is formed of stainless steel strands of 25 microns thickness, and is pressed to a thickness of 10-20 microns.

8. A method of forming a spectroscopic sample holder comprising the steps of:
-
providing a mesh formed from wires, pressing said mesh between hardened dies so as to Seduce its thickness to no more than 20 microns and such that its transmission is at least about 60% and mounting said mesh in a holder having an open aperture. - View Dependent Claims (9, 10, 11, 12, 13, 14)
