The 5249NF 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 5249 kit includes all ten different filters. Filters included in this set are listed below.
