Right Optical Comparator Dorsey Optical Comparators In the optical field, Dorsey is one of the few remaining domestically manufactured optical comparator product lines. Dorsey optical comparators demonstrate that attention to detail does matter and all are built on the foundation of stability and accuracy. Dorsey has tightened manufacturing tolerances to maintain uncompensated absolute inherent accuracy. Below we’ve summarized some of the main items that should be taken into consideration when buying an optical comparator. Step 1 – Which light path is best for your application, Vertical or Horizontal?...

Model 14HE Horizontal Beam The 14HE bench top comparator is Dorsey Metrology's basic and most economical comparator with the same high quality features as the other comparators in our product line, but in a smaller package and a lower price. The addition of our extra long life LED surface illumination is another Dorsey innovation. 14" (350mm) angled high resolution glass screen for optimum viewing with 90 degree cross lines, calibration reticle and chart clips Reversed and inverted profile image Machined chart ring with vernier protractor, 1 minute graduation facilitates optimal alignment Coated...

Benchmark 14H Horizontal Beam The Benchmark 14H is an Erect Image bench top comparator and is another example in our expanding range of products. This new comparator has the same high quality features as the current product line with an erect projection image, with our "ultra-precision" crossed roller bearing stage system, but in a smaller package. The measurement scales have zero backlash and are mounted in the center of the stage travel that provides maximum measurement accuracy. The optional extra-long life LED surface illumination is another Dorsey innovation. Erect and reversed profile image...

Construction features of our MODEL 16H The Dorsey Advantage Focus travel is always “optically coaxial” Unique design features an intermediate plate that allows the focus axis to travel independently of the X axis Ultra Precision Cast Iron Stage Large capacity 10" x 6" travel - 150 lbs stage system Optional 20” or 24" X axis travel Solid cast iron – no aluminum Lens is mounted to cast iron nickel plated stage – not to sheet metal case X Axis glass scale has zero backlash and is mounted directly under focal plane to greatly increase accuracy Y Axis glass scale has zero backlash and is mounted on...

Model 16H Horizontal Beam This extremely versatile measurement instrument features a robust cast granite composite base and our proven cast iron "ultra precision" stage system. This comparator comes standard with integrated fiber optic surface illumination. Measurement scales are mounted in the center of travel with zero backlash. A variety of readout options combine to make this one of the most accurate and versatile horizontal benchtop comparators. 16" (400mm) Vertical screen for optimum viewing Erect and reversed profile image High resolution ground glass screen with calibration reticle, 90...

Model 24P Horizontal Beam The 24P was designed to be an all purpose measurement/inspection instrument capable of performing both light and heavy duty tasks. Choose any lens system to customize this machine to match your requirements. 24" (600mm) Vertical screen for optimum viewing Erect and reversed profile image High resolution ground glass screen with calibration reticle, 90 degree cross lines and chart clips Machined chart ring with vernier protractor, 1 minute graduation Coated telecentric parfocal optics 3 position rotary lens & condenser turret (4 position optional) Quartz halogen profile...

Model 32P Horizontal Beam The 32P was designed with crisp, clear telecentric optics and a precision solid cast iron stage to be an instrument capable of handling almost any measurement/inspection requirement. This welded steel fabrication assures years of accurate, trouble free service. 32" (800mm) Vertical screen for optimum viewing Erect and reversed profile image High resolution ground glass screen with calibration reticle, 90 degree cross lines and chart clips Machined chart ring with vernier protractor, 1 minute graduation facilitates optimal alignment Coated telecentric parfocal optics...

32SS Horizontal Beam The 32SS offers the same quality features as the 32P Horizontal Beam comparator, however the 32SS offers an offset screen for working with large overlay applications. This machine has an erect correct image, a 9.5" working distance and through the lens surface illumination. 32" (800mm) Vertical screen for optimum viewing of erect and correct image High resolution ground glass screen with calibration reticle, 90 degree cross lines and chart clips Machined chart ring with vernier protractor, 1 minute graduation facilitates optimal alignment 6 position motorized lens turret...

Model 16VS Vertical Beam This dynamic vertical optical system is the first of its kind manufactured in the USA. This system allows a much greater stage capacity up to 75 pounds (15 lbs in the center of the glass plate) with optional stage travel up to 16" x 8". (400mm) Diameter vertical screen for optimum viewing 16" Reversed and inverted image High resolution ground glass screen with calibration reticle, 90 degree cross lines and chart clips Machined chart ring with vernier protractor High specification table (Part # 8x4MN-1) • 75 lbs stage capacity (15 lbs on glass) • 15" x 10.5" overall size...
