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.
Claims15
A spectroscopic sample holder comprising a mesh formed from strands of wire and supported in a frame having an open aperture, which mesh has been pressed to reduce its thickness to no more than 20 microns, the pressed mesh having a transmission of at least about 60%.
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.
A method of forming a sample holder for spectroscopy, comprising:
- providing a mesh formed from stainless steel wires of thickness in the region of 25 microns, said mesh having a transmission of about 80%, pressing said mesh between hardened dies so as to reduce its thickness to the region of 10-20 microns with a transmission of at least about 60%, and mounting said mesh in a holder having an open aperture.
