The Inconel coating on this fused silica filter is incredibly uniform—I tested it across several wavelengths and the attenuation stayed dead consistent. Wide spectral range means I don't need a second ND for most of my work.

I swapped this into my laser setup and the fused silica substrate handles the heat way better than the glass filter I used before. Attenuation stays flat across the whole range, no weird hot spots on the beam. Exactly what I needed for consistent power readings.

The fused silica substrate feels incredibly solid, and the Inconel coating gives a perfectly even darkening across the frame—no hot spots or vignetting to fight in post. I’ve already used it for long exposures in harsh midday sun, and the image stayed crisp with zero flare issues.
