Miniature Dual-Stage Isolators
Discover our innovative and compact free-space dual-stage optical isolators.
compact size
high isolation
high transmission
multiple wavelengths available (690, 780, 852 nm)
AOSense offers dual-stage, free-space optical isolators at 690 nm, 780 nm, and 852 nm for enhanced isolation. The innovative, small package size enables integration into compact laser sources and amplifiers without sacrificing transmission efficiency. The low external magnetic field enables the isolator to tightly integrate into systems with high magnetic-field sensitivity such as atomic spectrometers, magnetometers, clocks, and cold-atom devices.

(a) Free-space measurement with 0.26 mm beam diameter. Detector subtends 0.03 sr. Larger beam sizes may result in a different extinction ratio.
(b) Measured using fiber coupling in/out. Fiber coupling is >80%.
(c) Based on limited testing. Actual value is likely higher.
