Spectral confocal displacement sensor
H8A15 series | H8A18 series | H8A29 series
H8A15 series
New technological breakthroughs
We have independently developed and launched the first independent light input and output spectral confocal displacement sensor and split-channel optical fiber, which reduces optical path interference by more than 50% compared with traditional optical fiber, solving a problem that has plagued the industry for decades.
The highest testing accuracy reaches the sub-micron level, and it can measure the thinnest transparent films up to 8μm.
Ultra-high measurement accuracy
Industry-leading level, with product resolution reaching 1nm level.
We have independently developed a spectral confocal lens with a static repeatability of 10nm, a spot size as small as 3μm, a clear optical path, and ultra-high resolution that can accurately separate and measure the reflected light from the surface and back of ultrathin film samples.
High stability
It independently develops optical structures, possesses a stable and precise optical system, is not susceptible to harsh environments, and provides stable measurements.
It employs a highly efficient and accurate peak acquisition and filtering algorithm. This enables accurate and rapid acquisition of peak wavelengths, ensuring the linearity of the spectral confocal sensor's measurement accuracy.
- Ultra-small size
- The working distance and measuring range are moderate.
- Applicable to multi-point side-by-side detection
