The frequency-stabilized HeNe laser series manufactured by Japan Micro Optical Instruments achieves frequency stability with a measurement error of 0.01 nm - 1 nm per meter. As a laser light source mounted on measurement devices for lens measurement for smartphones and automotive cameras, flatness measurement of semiconductor wafers, and birefringence measurement for photomasks and exposure equipment stepper, it has a proven track record of over 1,000 units produced for domestic and international equipment manufacturers. We offer three types of lineup according to application and precision (YS-307 / QQD / QS). The 'QS' is a popular laser applicable to nanometer measurements across a wide range of fields. It stabilizes the power ratio of two oscillation modes, allowing output in both single mode and dual mode. By adopting a two-stage stabilization control and a dual heater system, it minimizes the impact of environmental temperature changes and expands the effective operating temperature range. This maintains frequency stability even under long-term continuous operation conditions. * For more details, please download the catalog or feel free to contact us.

This is a frequency-stabilized He-Ne laser manufactured by Japan Micro Optical Instruments, suitable for precise interferometric measurements in the nanometer to sub-nanometer range. We offer three types of models tailored to different applications and accuracy requirements (YS-307 / QQD / QS). <QS Main Features> - A popular model applicable for nanometer measurements across a wide range of fields. - Stabilizes the power ratio of two oscillation modes, capable of outputting in single mode or dual mode. - Maintains frequency stability even under long-term continuous operation conditions through two-stage stabilization control and a dual heater system. <Other Product Lineup> YS-307: Achieves ultra-high frequency stability of 10⁻¹¹, with frequency fluctuation width less than 1/20 of competing products, and simultaneously provides high output of 3 mW in single mode. QQD: A Zeeman laser with stabilized difference frequency of orthogonal two frequencies generated in a transverse magnetic field. It allows for easy configuration of a heterodyne interferometer with orthogonal two frequency outputs. *For more details, please download the catalog or feel free to contact us.
