slit & pinhole
APERTURES

Spectrophotometer entrance and exit slits. Imaging and alignment applications suitable for complete UV-IR frequency range. The metal profile is such that the minimum dimension of the aperture is within a micron of one face. Aperture sizes are measured at up to 1000x magnification, and the tolerances mentioned apply to the width throughout the length.

Each slit is centered in a copper foil disc, 25 microns thick, mounted in a recessed hole in an anodized aluminum holder. 16mm diameter.

RANGE: TOLERANCE:
1-25 micron +/- 0.5 micron
26-100 micron +/- 1 micron
101-500 micron +/- 2 micron
