Product Overview

Evaluate Economy Dielectric Longpass 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.

Review transition steepness, blocking depth and passband transmission rather than selecting by cut-on wavelength alone.

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

Review transition steepness, blocking depth and passband transmission rather than selecting by cut-on wavelength alone.

Need a different diameter, tolerance or coating?

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