Neutral density laser radiation filters with custom transmittance, dimensions and shape. Neutral density absorption type filters decrease intensity of light without altering the relative spectral distribution of the energy. Attenuation is accomplished by using an absorbing type glass. 

 

  • Neutral Density filter is an economical solution to attenuate light
