Note:
These objective lenses are designed to image the workpiece in depth of field (wavelength in visible light (wavelength = 620 nm) and near-ultraviolet light (wavelength = 355 nm).
When time changes). Therefore, the M Plan NUV series is suitable for laser repair using high frequency laser beams.
