To maintain the pace of new product innovations,
the company makes a major investment in research
and development, with the R&D function at the
forefront of company activity.
Research and Development personnel constantly
monitor key areas relating to filters and the situations
in which they are used, always seeking to relate new
developments to future manufacturing techniques.
Among the most important areas of detailed
interest are:
developments in the polymeric materials which
are the basis of Lee lighting filters;
lamp and recording media technologies, because
modern designs make increasing physical and
technical demands on filters;
the availability and performance of chemicals used
in colourants is monitored in the quest for an even
wider range of accurate and consistent colours.
Lee mixes its own dyes to ensure reliability;
Additionally, Lee executives pay very close attention
to feedback from end-users. Often, comments or
individual requests from end-users will prompt
research into new areas of filter performance,
and this can eventually result in “customer-driven”
products which fulfil a defined market need.
The ability to create a wide range of products is
only an advantage if the high quality of every filter
produced can be guaranteed.
Lee Filters has developed sophisticated quality
control systems based on purpose programmed
spectrophotometers. But consideration is always
given to that most incredible of all optical instru-
ments - the human eye, which will eventually
receive the created colour stimulus.
Every filter leaving the factory is accurately checked
against a scientifically generated set of parameters.
At Lee Filters, there is only one pass mark - 100%.
