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 &mu,m. 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.
