M95 Plan Apo Industrial Objective Lenses

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 a) NUV Range Name (objectives) Magnification Numerical aperture(N.A) Working distance (mm) Conjugate distance(mm) Parfocalization distance(mm) Infinity M Plan APO HL Objective (NUV) 20X 0.40 17.15 ∞ f T=200 95 50X 0.43 14.81 50X 0.70 3.50     b) VIS Range Name (objectives) Magnification Numerical aperture (N.A) Working distance (mm) Conjugate distance (mm) Parfocalization distance (mm) Infinity M95 Plan APO SL Objective (Visible) 2X 0.055 34.60 f=200 95 5X 0.14 44.50 ∞ f T=200 95 10X 0.28 34.00 20X 0.29 31.00 50X 0.42 20.50 100X 0.55 12.50       c) Near Infra Red (NIR) Obj lenses Name Magnification N.A.
