SHARPLES STRAIN VIEWERS (Polariscopes)
for the QUALITY CONTROL of GLASS and PLASTICS.

Sharples Strain Viewers have been manufactured for over 50 years in the United Kingdom and have been supplied to most countries worldwide.

Strain Viewers have for long been used in the GLASS INDUSTRY for the examination of a wide range of glass products to determine the residual stresses in them. Strain Viewers can be supplied for either qualitative or quantitative analysis, but of late, it has become more important to have quantitative measurements when setting quality standards.

In the past few years Strain Viewers have become increasingly popular within the PLASTICS INDUSTRY.

Some of the industries where Strain Viewers are used include: -


GLASS     -     flat, automotive, container glassware, domestic glassware, scientific                          glassware, pharmaceutical glassware, tubular glassware, television and                          cathode ray tubes, illuminating glassware etc.

PLASTICS -   PET bottles and preforms, compact discs, injection moulded                          components, acrylic sheets, plastic bags, film etc.

In fact Strain Viewers can be used to examine any glass or plastics products which are transparent.


Sharples manufacture a wide range of Strain Viewers to suit all applications, eg, On-Line, Large Field etc. A selection of our most popular Strain Viewers are shown below : -      please click on image or link for details
