What is M95 and why M95?

M95 objective lenses have total parfocal length of 95mm and mainly used with metallurgical or industrial microscopes. This is why they are called M95. FYI, regular objective lenses in biological and metallurgical microscopes are mainly M45 (45m mm parfocal length), while there is M60 also available for some applications.

The M95 are excellent choices for long working distance microscopy optics. They have great combination of long working distance and resolution at the same time. These lenses use mainly foal length of 200mm which is written on the lens enclosure.

These lenses can easily replace Mitutoyo lenses. They use the same thread of M26.

 

M95 Plan APO Objectives for Metallurgical/Industrial  Microscopes, Visible, NIR and NUV

The M95 objective lenses are offered at different wavelengths:

  • a) Visible (VIS) range (400-700nm)
  • b) Near Infrared  (NIR) range (650-800nm) which are also suitable for VIS range
  • c) Near Ultraviolet range (200-400nm), which can also be used for VIS range Plan Apo 20
