STANDARD OPTICAL COMPARATOR CHARTS
GLASS CHARTS
Dorsey Gage Company, Inc uses satin ground glass of superior quality for all our glass charts. The images
are very durable and will last for many years with proper care. Glass charts should be cleaned ONLY with
mild soap and water solution using soft cotton cloth. Window cleaners, thinners, and alcohol should
NEVER be used to clean your glass chart. All glass charts are traceable to the N.I.S.T. and are available
with certification at no extra cost.
Glass charts are typically required when:
•
The existing chart has been severely chipped or broken
•
The lines on the existing screen have faded or worn off
The new chart will remain in the comparator for an extended period of time
OVERLAY CHARTS
Overlay charts are made of plastic and are placed over the existing glass screen. They are typically
required when charts are interchanged on a frequent basis. Dorsey Gage offers 4 types of plastic overlay
material:
•
.007" thick clear mylar
•
.007" thick frosted mylar
•
.050" thick clear vinyl
• .050" thick frosted vinyl
SCALES
Dorsey Gage also offers 3 types of scales:
•
Inch/decimal
•
Decimal/metric
•
Multi-magnification
The inch/decimal and decimal/metric scales are available in glass and are useful for sight verification.
The multi-magnification scales are useful for direct screen measurements of projected images on a
comparator that is not equip with either digital readouts or micrometer readers. These scales are
available in glass or 050" thick vinyl.
All scales are traceable to the N.I.S.T. Certification sheets specifying traceability are available at no
extra cost. Glass scales are available with serialized numbers.
All scales are intended for sight verification and NOT for comparator calibration.

Custom Comparator Charts
In addition to standard comparator charts, we
pride ourselves in the ability to provide custome
charts of any nature, regardless of complexity or
size.
Charts are designed on a CAD system from your
drawings, plotted on precision machines, and
reproduced on the same materials available for
our standard charts.
If you design your own charts but lack
reproduction facilities, we can produce your CAD
data and provide you with a finish chart at a
significant reduction in cost. Ddata can be sent
via mail or modem. Call for more information.
Custom comparator charts are also traceable to
the N.I.S.T. certification sheets specifying
traceability and are available upon request at no
additional cost.
