Autofocus unit for circuit board inspections
| Category | Other |
|---|---|
| Workpiece | Liquid crystal polymer circuit board/film/etc. |
| Inspection details | High speed inspection of liquid crystal panels using infrared light |
| Application | Camera (autofocus) |
This is an autofocus unit for subjects including liquid crystal glass circuit boards, films, and metals. It is able to adjust the focus quickly and with high precision using infrared light, and then take images.
[Specifications]
- Distance measurement using infrared or visible light
- Magnification
- Search speed: 0. 3 seconds (20x objective lens; search width ±250μ)
High-speed and low-cost autofocus is possible by combining it with a microscope unit. The function of line sensors, which work well with glass and transparent materials, is strengthened by using both unique arithmetic processing and a CCD line sensor. This allows for over 2 times faster speeds than conventional systems, as well as for tracking functions.
