• Video-Dedicated Microscope Objectives
• 17.5mm and 37mm Working Distance Options
• Designed for Use in Conjunction with InfiniTube™ Products
Infinity Achrovid™ Microscope Objectives are a cost-effective complement to traditional Mitutoyo Long
Working Distance objectives. All Achrovid™ objectives are infinity corrected and have a M26 x 0.706 (36
TPI) Whitworth common thread. These objectives are compatible, via adapter, with the InfiniTube™ Standard
Systems, InfiniTube™ Ultima Microscope Tube Lenses, and InFocus™ Dynamic Optical Focusing Systems.
• Enable Dynamic Optical Focusing and Reduce Spherical Aberration
• Compatible With All Infinity-Corrected Objectives
• Color Matched for Major Brand Objectives
InFocus™ Dynamic Optical Focusing Systems are used with microscopes to enable dynamic optical focusing,
and drastically reduce the spherical aberration caused by the sample’s cover glass thickness or suspension
fluid. These dynamic optical focusing systems eliminate the need for correction collars and expensive
motorized computer activation. InFocus™ Dynamic Optical Focusing Systems allows micromanipulation of
the microscope, and can be integrated with any infinity corrected objectives. Variations in magnification are
minimal over the range of focal translation. InFocus™ Dynamic Optical Focusing System modules are color
corrected for Mitutoyo, Achrovid, Zeiss, Leica, Nikon, or Olympus objectives and can be connected to most
major brand microscopes using a series of stand adapters (sold separately).
