M Plan Apo NIR B:
Note:
This series of objective has greatly improved in operability thanks to the achievement of an ultra-long working distance of 25,5 mm while maintaining the NA of the NIR series 20X/50X.
M Plan Apo NIR:
Note:
These objective lenses are designed so that the image of a workpiece remains focused within the focal depth even when the wavelength used is changed from within the visible range up to the near-infrared (480 to 1,800 nm).
Therefore the M Plan NIR Series are suitable for laser repair. However, when the wavelength used exceeds 1,100 nm, the focussing position may deviate slightly from that in the visible range due to changes in glass dispersion and refractive index.
