HOI Optical Isolators
From $420 USD
Request a quoteProduct description
HOI optical isolators combine a polarizing beamsplitter prism with a zero-order quarter-wave plate whose optical axis is oriented at 45°. The source describes p-polarized transmitted light becoming circularly polarized, and reflected return light becoming s-polarized after a second pass so that the beamsplitter diverts it.
Listed design wavelengths are 532, 633, 780, 1064 and 1550 nm, with 5×5×5, 10×10×10 and 12.7×12.7×12.7 mm sizes. Review the individual model values. Isolation is listed as >20 dB; source reference curves are wavelength-dependent and do not establish a uniform value outside each model’s design conditions.
The model wavefront entry reads 1/4 at 632.8 nm without a wavefront unit; it is preserved with that ambiguity. Category common values separately state <λ/4 per 25 mm at 632.8 nm and beam deviation <3 arcmin, while model beam deviation reads 3 arcmin. These category thresholds do not overwrite the individual model entries.
Schematic
Optical path reference; not a manufacturing drawing.
Listed model materials are K9 glass and quartz crystal.
The source damage threshold is >500 mJ/cm², 20 ns, 20 Hz at 1064 nm. That test wavelength remains attached to the threshold even for models designed for other wavelengths. The source RoHS compliance statement is shown as an unverified source claim; no certification document is supplied.
