ND Filter Set, Metallic, Borofloat, Qty 6

The 5247NF Neutral Density (ND) Filter Set contains the same filters that we use in our ND-filter wheels. Made with Inconel® metallic coatings on glass substrates, these ND filters provide spectrally uniform attenuation over the wavelength range from 0.4 to 2.0 μm. The reflective nature of the coatings helps reduce thermal effects when these filters are used with moderate-power lasers. The Model 5247 filter kit provides a large range of attenuation with six filters having optical densities of ~0 to 2.5 in steps of 0.5. Filters included in this set are listed below.
