ASP-UV-Plan-APO Series Super Long Working Distance
- Resolution: 0.6µm
- Wavelength: 345-1064nm
- Depth of focus: 1.1μm
- N.A: 0.5
Bright field super-long working distance objective lens. The focal plane is corrected for both Bright Field and Near UV (366nm), meaning both wavelength will be in focus. Sytem is optimized for high transmittion at 355m,. such that a microscope fitted with a yag laser can be used for repair of semiconductor and LCD circuits.
