FIXED NARROWBAND "ASPIRIN TABLET" ISOLATORS (IO-D SERIES)
Catalog Number	Aperture	Select λ between	Use between	Trans.	Iso.	Max. Power (cw)
IO-D-λ	1.75 mm	760-810 nm **	± 6 nm	48-55%	> 38 dB	80 mW
IO-D-830 *	1.75 mm	830 nm **	± 6 nm	35%	> 38 dB	60 mW
IO-D-850 *	1.75 mm	850 nm **	± 6 nm	25%	> 38 dB	50 mW
See body type D * IO-D isolators have VLP polarizers. Proper alignment of VLP polarizers is required because of absorption concerns. Discuss with OFR. ** Other wavelengths are also available. Discuss with OFR.
