Overview
Pure Attenuation: Absorptive Neutral Density Filters for Accurate Metrology
The VenusLab VLND Series consists of absorptive neutral density filters used to control light quantity. Their core advantage lies in "optical neutrality," meaning the filter's transmission characteristics are largely independent of the incident wavelength.
Light passing through the filter is attenuated in intensity while its color remains unaffected. This property makes them indispensable standards in imaging systems and spectral analysis. Offered in both circular and square shapes to suit various mounting requirements, the VLND Series delivers stable, repeatable attenuation for both precision laboratory setups and industrial inspection integration.
