Near Ultraviolet Objective (M iPlan Apo NUV Series)
- Chromatic Aberration is compensated from visible range to near ultraviolet range. And Visible area with high resolution power spreads the whole field of view.
- Have high resistance against laser SHG (532 nm) so it is suitable for the repair of semiconductor circuit or LC board.
- Confocal distance 95 mm.
