光響 Product Lineup

The Japanese Micro Optical Device's frequency-stabilized HeNe laser series achieves frequency stability with a measurement error of 0.01 nm - 1 nm per meter. As a laser light source mounted in 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 cumulative production record of over 1,000 units for domestic and international equipment manufacturers. We offer three types of lineup according to application and precision (YS-307 / QQD / QS). The 'YS-307' utilizes the "frequency pulling phenomenon" to achieve ultra-high frequency stability of 10⁻¹¹, a frequency fluctuation width of less than 1/20 compared to competing products, and high output of 3 mW in single mode simultaneously. By locking the mode at the center of the Ne gain curve, it also achieves high frequency reproducibility upon restart in addition to high output. By adopting a two-stage stabilization control and a two-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.

The Japanese Micro Optical Device's frequency-stabilized HeNe laser series achieves frequency stability with measurement errors of 0.01 nm - 1 nm per meter. As a laser light source mounted in 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 'QQD' is a Zeeman laser that stabilizes the difference frequency generated by orthogonal two frequencies in a transverse magnetic field. It allows for easy configuration of a heterodyne interferometer with orthogonal two frequency output. By adopting a two-stage stabilization control and a dual heater system, we suppress the influence of environmental temperature changes and expand the effective operating temperature range. This maintains frequency stability even under long-term continuous operating conditions. * For more details, please download the catalog or feel free to contact us.

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.
