Glass Neutral Density filters attenuate light by absorption just like the gelatine neutral density filters. Glass ND Filters are more robust and tend to have more uniform absorption characteristics. They also attenuate by absorption and so care must be taken to avoid overheating. Attenuation is achieved by polishing glass to the correct thickness. Knight Optical offers stock absorptive ND filters in 12.5mm and 25mm diameters, and 50x50mm squares manufactured from high quality glass. Each filter is available with blocking between 0.1 and 4.0 OD and are available to purchase direct from this page. In addition to our stock absorptive glass ND filters, Knight Optical also offers an extensive custom optic service thanks to our many years of experience in the industry. We can supply ND filters cut to sizes and shapes to fit individual application and mount filters where applicable. READ PDF FOR FULL SPECIFICATION
