This is an unusual neutral density filter on a wafer-thin glass substrate. The optical density is marked on the surface of the filter (0.96) in blue ink. I have not attempted to remove the marking. The filter is very uniform in density (the gradation visible in the photo is an artifact of the lighting). There are a few fine scratches in the coating near the edge with the marking. There is also a fine scratch in the glass on the side opposite the coating (see second photo). It extends most of the way across the filter.

Diameter � 2.000 inches
Thickness � 0.029 inches (0.75mm)

This Newport 900PH-10 High Energy Pinhole Aperture comes from a working environment but has not been tested.

From manufacturer website: The 900PH-10 High Energy Pinhole Aperture is fabricated from ultra-thin molybdenum, a refractory alloy with high heat conductivity and melting point. This material exhibits almost no warping due to localized heating by the laser. A smooth 10 � 1 �m diameter hole with extremely low ellipticity is produced using laser drilling techniques. These pinholes have a laser damage threshold of 75 MW/cm2 CW and are suitable for pulsed laser use up to 700 mJ/cm2. This version is mounted for use with our Model 900 spatial filter.

– Aperture Diameter: 10 +/- 1 um.
