Quality Assurance Capability
The PWT philosophy is to “manufacture to quality” rather than to “inspect to quality”,meaning that the pursuit of perfection is integrated within all of the operational step, as opposed to the flawed paradigm of waiting until the final inspection stage to discover imperfections.

Mira White-Light Interferoment
White light interference theory:
For an flat surface, the interference fringes is flat. As long as the measured surface is uneven, the interference fringes have fluctuated.

Spectrophotometer -UV3600
A high-performance double monochromator makes it possible to attain an ultra-low stray-light level (0.00005 % max. at 340 nm) with a high resolution (maximum resolution: 0.1 nm). The wide wavelength range of 185 to 3,300 nm enables measurement across the ultraviolet, visible, and near-infrared regions.
This instrument can p erform spectrophotometry for a variety of applications.
