The 5247 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. The set includes the following ODs: 0.04, 0.5, 1.0, 1.5, 2.0, 2.5.


5247中性密度(ND)过滤器集包含与我们在ND过滤器轮中使用的相同的过滤器。用铬镍铁合金®金属涂层在玻璃基板上,这些ND过滤器提供了可怕地均匀衰减在波长范围从0.4到2.0μm。涂层的反射特性有助于减少与中等功率激光器一起使用时的热效应。5247型滤光片提供了很大范围的衰减，六个滤光片的光密度在0.5级~0 ~ 2.5之间。该集合包括以下ODs: 0.04、0.5、1.0、1.5、2.0、2.5。
