basic information
Measure extremely small displacement quantities non-contact using laser light! The optical heterodyne displacement meter is optimal for measuring transient response phenomena. 【Features】 ○ 1nm resolution 0.001 microns in vertical resolution The measurement reference is the wavelength of a frequency-stabilized HeNe laser. ○ Records transient phenomena at intervals as short as 1μs Measures, records, and displays rapidly changing events. The fluctuations are clearly visible on a PC's LCD screen. ○ Records up to 1 million points and processes data Significantly increases recording time. The vast number of recorded points can all be processed on a PC, with filtering and Excel conversion possible. ○ Eliminates error factors based on base vibrations through relative measurements Measures the relative displacement values at two measurement points. Clearly identifies only the relative fluctuations, allowing for the removal of error factors such as base vibration components. ● For other functions and details, please download the catalog.

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.
