Optical Measuring Instruments

The Electronic Eyepiece Micrometer M202EE converts your microscope into a electronic digital measuring microscope with resolutions to a fraction of a micron.
A Linear Slide USB camera or microscope with a 130mm range makes digital readings to 0.0001 mm or 50 millionths of an inch.
Our Differential Stress Refractometer LDSR measures stress in commercial float, plate and sheet glass.
The Z87.1 Mini-Dioptometer checks goggles, welder’s lenses and eye glasses to the ANSI Z87.1 standard.

Used in place of the eyepiece and eyepiece adapter to convert virtually any microscope into a electronic digital measuring microscope with resolutions to fractions of a  micron. The M202EE has a movable crosshair attached to a precision rotary encoder that sends the reading to a small digital display. The electronic display can be user programmed for inch or metric reading.

Electronic Eyepiece Micrometer M202EE

These models are equipped with the M202EE electronic micrometer and have a cross hair that moves across the field of view using a precision micrometer screw. Model M110BEE reads to 0.0001mm at 25X  magnification with a 4.7mm range and 67mm working distance. Model M115BE reads to 0.00001 inches.  Other calibrations and working distances are available.

Differential Stress Refractometer LDSR

Provides a non-destructive means of measuring stress in the surface layer of commercial float, plate and sheet glass. The Refractometer can be used on glass which has a refractive index in the range of 1.516 up to 1.566. This index range can be changed by substitution of optional prisms.


Z87.1 Mini-Dioptometer System

Check goggles, welder's lenses, and eye glasses to ANSI Z87.1 standards for refractive power, prismatic power and definition. Easy and convenient to use.
