HS-830 Foreign Matter Inspection Device for FPDs
Overview
Like the HS-730, the first inspection device in the industry to offer sub-micron sensitivity, the HS-830 is infused with all the top-notch optical technology that we at Toray Engineering have to offer. This device enables you to detect foreign matter on glass substrate in a quarter of the time it used to take.
Features
- Allows swift, high-sensitivity inspections, e.g., 86 seconds when inspecting 1100mm × 1300mm substrate.
- New inspection system combines traditional laser scattering methods with image detection opticals to achieve a high level of inspection reliability and spatial resolution.
- High spatial resolution and review capability: high degree of foreign matter position detection precision enables review with high-magnification microscope possible—impossible with older types of inspection devices.
- High-magnification review function (total magnification up to 2000 times when converted for 14” monitor) included as standard feature.
