Product Overview

Evaluate Visible Absorptive Neutral Density Filter across the complete spectral requirement

Spectral edges, center wavelength and attenuation values are specified for defined measurement conditions. Angle and temperature can shift interference-filter response.

Check OD, transmission, thickness and heat load; absorptive filters can warm under high optical power.

Spectral behavior

Spectral edges, center wavelength and attenuation values are specified for defined measurement conditions. Angle and temperature can shift interference-filter response.

Selection and incidence conditions

Check OD, transmission, thickness and heat load; absorptive filters can warm under high optical power.

Need a different diameter, tolerance or coating?

Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
