Demonstrating stable accuracy in measurements at ultra-high resolution of 1 nm!
This is a light source for optical heterodyne displacement measurement. It is an essential item for achieving high resolution and high precision, and is indispensable for optical measurements. For high-precision measurements, the stability of the "ruler" is desired. The HeNe laser serves as a reference laser due to its stable frequency as a gas laser. However, even in a free-running state (simply connecting the laser to a power source to turn it on, in a commercially available emission state), the frequency stability is high at f/f ~ 10, but it is insufficient for measurements with high precision, particularly at a resolution of 1 nm. Frequency-stabilized lasers enhance frequency stability and improve the reliability of high-precision measurements. They are essential for conducting high-precision optical measurements. (The frequency stability is highest in solid-state lasers, followed by gas lasers and semiconductor lasers. However, solid-state lasers are expensive, and semiconductor lasers do not provide sufficient stability. Gas lasers are the most practical. However, there are no stabilized lasers for argon lasers or HeCd lasers.) *For more details, please inquire through a request for materials or download.*

Company information
We have established 'High-precision measurement of physical quantities using light' as our management policy. Optical measurement technology has become an indispensable element of modern cutting-edge technology. We are confident that the demand for high-precision measurement will grow stronger with the advancement of science. By combining high-precision measurement with the excellent properties of light—non-invasive, non-intrusive, non-contact, and high-precision—we can expect further technological innovation. It may not be suitable for measuring mass-produced items, nor for online measurements. However, we are committed to making it useful for cutting-edge industries that require high-precision measurement of physical quantities.
