These filters are precision polished for demanding research or OEM applications. Three sizes are available 12.7 and 25.4 mm round and 50.8 mm square. The 25.4 mm diameter and 50.8 mm square filters are permanently marked with the optical density and are available individually or in a set of nine. • New 12.7 mm diameter size • Broadband attenuation, visible to near IR • Absorptive neutral density glass • 25.4 mm dia and 50.8 mm square sizes are permanently marked with the optical density • For lower power applications Specifications Material Neutral density colored glass (BK 7 or equivalent for 0.05 OD) Clear Aperture central 80% of dimensions Surface Quality 60-40 scratch-dig Dimensions ±0.3 mm Thickness 1.57–4.19 mm (0.05 OD, 3.0 ±0.1 mm) Wedge 3 arc min Chamfers 0.25–0.76 mm face width x 45° ±15° Angle of Incidence 0° Optical Density Tolerance ±4% at 546.1 nm Cleaning Non-abrasive method, acetone or isopropyl alcohol on lens tissue recommended (see page 622) Damage Threshold 30 W/cm2 CW, typical Note: Due to the absorptive nature of the filter glass, use with high power lasers should be avoided.
