Specifications 1 Circular Variable Metallic ND Filter
2 Wavelength:400-1100nm
3 Daimeter:50mm
4Optical Density:0.0-1.0 OD
The OQVND 5010 Circular Variable Metallic ND Filter It is 50 mm in diameter with surface flatness of ≤1λ , and coated for an OD range of 0.0-1.0. Our circular variable neutral density filters are designed to simplify attenuation and beamsplitting in the visible to NIR. The variable attenuation and beamsplitting around a 270° circle is achieved by a thin, reflective aluminum film. A broadband, visible AR coating on the back side allows the filter to be left in the beam path at all times with minimal losses or ghost images. The drawing:
