IOT-any of above: Isolation is ~60 dB. Transmittance is squared.
* Do not use outside limits in “Select Center λ” column without discussing with OFR.
** Transmittance varies with wavelength. Discuss with OFR.
*** PHE polarizers are similar to VLP. Proper alignment of PHE and VLP polarizers is required because of absorption concerns. Discuss with OFR.
