25.4 mm Absorptive ND Filter Optical Density - 0.1
Compare
This series of absorbing glass neutral density filters is offered in small increments from D=0.1 up to D=4. The thickness of the filters is controlled to produce a calibrated optical density at 546 nm. The response is approximately neutral so they can be used as broad band devices. However, if used at other wavelengths the optical ...
