MMS® Imaging Lenses

  • Available for Infinity Corrected Objectives
  • Designed for OEM Integration
  • Focusable with Adjustable Iris
  • Requires a Front Objective and Rear Lens Assembly

Designed for flexible integration, our Modular Magnification System (MMS®) imaging lenses feature an adjustable iris and fine focus that can be locked in place. A complete system requires a front objective and rear lens assembly. A variety of both components are available and can be interchanged to produce different magnification/working distance combinations. Nominal working distances of 67mm, 91mm, 116mm or 141mm are available, with resolutions as high as 114 lp/mm. The ±8mm of focus adjustment allows for a range of fields of view and working distances with one set of components. Depending on components chosen, distortion as low as 0.13% can be achieved using a 2/3" format sensor. When used with a smaller sensor, even lower distortion values can be reached.


  • Available in a Variety of Options
  • Flexibility and Cost Savings
  • Front Objective Kit Includes Objectives 7, 9, 10 and 11
  • Rear Assembly Kit Includes Rear Objectives R-1, R-2, R-3, R-4, R-200, R-5 and R-6

A complete system requires a front objective and rear lens assembly. The Front Objective Kit includes: Obj-7, Obj-9, Obj-10 and Obj-11. The Rear Assembly Kit includes: R-1, R-2, R-3, R-4, R-200, R-5 and R-6.

MVO® MMS® In-Line Attachment

  • Compatible with Entire Line of MMS® Lenses
  • Provides Even Illumination Across the Field of View

This in-line attachment has been specifically designed for our MVO® MMS® Lenses. It is equipped with C-Mount threads so that it can be inserted in between the rear assembly and the front objective to create a complete in-line system. Focus adjustment allows for optimum coverage for each objective. Light guides and illuminators available separately.

MMS® to Mitutoyo Adapter for Infinity Corrected Objectives

  • Higher Magnification Range than MMS® Front Objectives
  • Recommended for M Plan Apo 2X to 10X Mitutoyo Objectives

The MMS® to Mitutoyo Adapter increases the flexibility of our MMS® modular system. Easily integrated, it simply attaches to the selected MMS® Rear Assembly before connecting the desired Mitutoyo objective (M26 x 36 TPI). Adapter extends the MMS® magnification range from 0.5X-4.0X to 0.75X-16.5X. The high magnification and diffraction limited performance of the Mitutoyo objectives coupled with the MMS® Rear Assemblies allows for more working distance (WD) and field of view (FOV) combinations. Note that the MMS® to Mitutoyo Adapter can only be used with infinity corrected objectives (Compact and Telecentric Mitutoyo objectives will not work). The adapter only adds 12.4mm to the length of the system (not including the objective).

Using this adapter, the MMS® In-Line Attachment can also be added for illumination with the Mitutoyo objectives. Note that vignetting may occur as iris closes due to the objective aperture.
