Product documentation


●Supports a large format camera, up to 1.9 inch sensor size.
●Use of the high luminance LED enables high maintainability.
●The world's only autofocus system that utilizes line sensor (one-dimensional image sensor).
●Supports both high-reflectance material surfaces and low-reflectance surfaces such as paper or filters. Also performs well on glass and transparent plastic, which is not possible with other methods. Our sutofocus system is high-functioning, and there are few unsuitablesamples.
●World's leading tracking performance. Newly-developed two-line-sensor method for high-speed tracking of undulations and slopes can maintain continuous focus even when tracking a glass substrate moving on a high-speed stage at 2m/s.
*With a 20X objective lens and vertical displacement of ±150μm.
●Supports a broad range of magnifications from macro to micro.
