Bulge tester thin film Young's modulus measurement device
Measurement of the Young's modulus of thin films by applying uniform stress to the thin film and measuring the amount of strain. A bulge tester that utilizes the highly versatile characteristics of an optical heterodyne displacement meter. 【Features】 ○ Control of the heterodyne displacement meter, pump operation, and valve operation via PC to acquire data. The acquired data is used for curve fitting to determine the Young's modulus and internal stress. ○ Non-contact and high-precision measurement. ○ Fully automated measurement, with easy repeatability. ○ Compatible with various thin films by replacing the thin film fixing part. ○ Displacement resolution: 1nm (when using HV400), 10nm (when using HV250). ○ Pressure measurement resolution: 0.1Torr. ○ Maximum applied pressure: -300Torr. ○ Maximum sample diameter: 15cm. ○ Maximum diameter of the sample in the measurement area: 50mm. ○ Measurement modes: fully automatic mode or manual mode. ○ Automatic control capability through changes in vacuum systems, stage systems, etc. Specifications such as stress range can be customized according to user requirements. ● 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.
