[Product] Frequency Ultra-High Stabilization HeNe Laser

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 measuring 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). YS-307: Achieves ultra-high frequency stability of 10⁻¹¹, frequency fluctuation width of less than 1/20 compared to competing products, and high output of 3 mW in single mode simultaneously. QQD: A Zeeman laser that stabilizes the 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. QS: Stabilizes the power ratio of two oscillation modes, capable of outputting in single mode or dual mode. A popular type of laser applicable for nanometer measurements in a wide range of fields. * For more details, please download the catalog or feel free to contact us.
