This 1″ square aperture holder allows interchanging pinholes drilled in 9.5mm metal foil discs. It is ideal for use in the environments where no outgassing is permitted. The combination of the materials with different thermal conductivities extends the pinhole life under the fluencies close to the ablation threshold sometimes from minutes to days. The geometrical design is robust to the large temperature range. The threaded 8-32 mounting hole is centered on a side and can be interfaced with optical posts and stages.
