Visible & Near Infrared Neutral Density Filters (ND)
- Reflective Metallic Films on glass
- Densities from 0.04 to 4.00
- Optical Density = log (1 / T)
Reflective metallic thin films deposited on glass permit attenuation of an optical system with negligible absorption. They reflect part of the incident radiation permitting only a fraction to be transmitted. A filter set of 11 different OD’s of the same size is also available. Each filter will be provided a transmission scan at 546nm.
