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.
