How to choose
within this family.

01

Locate the lower boundary

Compare the cut-on edge with the shortest wavelength you need to retain.

02

Check the longer-wavelength window

Inspect the full useful region above the edge, including any secondary changes in transmission.

03

Review the transition region

Signals close to the cut-on may be partly attenuated; compare the actual curve at those wavelengths.
