Radiusgauges, Lensmeters, Microscopes

  • Radiusguages +

    Radiusgauges are available with either a standard or digital display and in either monocular or binocular form. All offer the functions of two instruments in one, measuring both the curvature and thickness of contact lenses on a single instrument.

The accuracy of both measurements is increased through the 100x magnification and a coaxial coarse and fine focusing knob.

  • Lensmeters +

    Well suited for measuring soft and hard contact lenses, the Marco Lensmeter 101 is a compact deluxe model with a full 90-degree inclination. This is especially suited to the measurement of contact lenses when used in the vertical position.

    Standard equipment on the 101 includes such deluxe features as a prism compensator, external power and axis readings, and an American-style cross-line target. The oversized lens table permits the measurement of conventional lenses from 30 to 90 mm in diameter. The instrument is well suited for laboratory or office use.

  • Microscopes +

    A good choice for an ophthalmic lens laboratory microscope, the EMZ5 is Sterling’s choice for high quality instrument at an affordable price. 

It is a binocular stereo zoom microscope with stand, which comes with an 0.7x to 4.5x objective lens (the lower lens) and 10x eyepieces. There are also 12.5x, 15x, 20x or 30x eyepieces available. 

The optics are “wide field” types, and are of high quality, giving a wide, crisp, and bright image with very good inherent depth-of-field (the portion of the image seen which is in focus from front-to back, or how much of the image can be brought into focus at one time.
