Product Overview

Evaluate 30 mm Cage Variable Attenuator 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.

Select the wavelength version and OD range, then verify mounting-hole compatibility and minimum transmission.

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

Select the wavelength version and OD range, then verify mounting-hole compatibility and minimum transmission.

Need a different diameter, tolerance or coating?

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