Neutral Density filter is an economical solution to attenuate the light
For your convenience, we have selected 11 pcs of the nneutral glass filters for various applications in the laboratory! Filters are assembled in safe and compact wooden box
Neutral density filters are ideal for overall light reduction in
cases of extreme light intensity. Neutral density laser radiation
filters with custom transmittance, dimensions and shape. Neutral
density absorption type filters decrease intensity of light without
altering relative spectral distribution of the energy. Attenuation is
accomplished by using an absorbing type glass.
