    Technical Information

    ND400 absorptive neutral density filters have an optical density of 4.0, meaning that they transmit an average of 0.01% of visible light. Surprisingly, this amount of light passing through the filter is easily detectable by the human eye. Because the glass substrate is absorbing 99.99% of the light that passes into the filter, it is not recommended that these filters be used in laser applications or immediately in front of high wattage lamps.

    • Useful Range : 425-675nm
    • Optical Density : 4.0
    • Average Transmission: 0.01%
    • Tolerance : +/- 0.003%
    • Surface Quality : 40/20
     
     
    Note: Midwest Optical filters are considered to be special order items and are thus not returnable.
