Acrylic
Sheet and Windows - Perspex
Acrylic
is a light weight plastic which offers many of the
benefits of glass, such as high optical clarity and
excellent scratch resistance, whilst being easy to
machine in complex shapes. Ideal for LCD display window
or a variety of optically clear covers. It can be supplied in sheets
or machined to your drawing. Available in a wide variety
of sheet thickness, colours and surface finishes. We
also offer Laser
Cutting Services for finished products

Surface
Finish
Gloss
A cast acrylic sheet with a standard gloss finish.
Cast non-glare
A cast acrylic sheet with a non-dispersive etch to
eliminate surface reflections. Suitable for applications
with bright overhead lighting or where the screen may be
in direct sunlight.
Colours
Coloured
acrylic sheets can provide effective contrast
enhancement for coloured displays. Typical applications
are LED, Vacuum Fluorescent and Electro-luminescent
displays, where the filter accentuates the colour of the
emitted light, making the back of the display appear
darker.
Specific
colours can be matched. There is a minimum order
requirement of 5 sheets.

Handling
All
filters are packaged with a protective foil on both
sides or wrapped in tissue. We recommend that the
filters are stored like this. For all filters, try to
limit the number of occasions the filter is handled as
this can easily damage it. A few important hints are
listed hereunder:
- Handle
filters by holding at the edges
- Do
not remove the protective foil until final
installation of the filter. Inspect the filter by
holding it at the edges and peeling back the foil
halfway. Replace the foil and then repeat for the
other half of the filter.
- Inspection
should be carried out in a clean, dust-free
environment. Always use lint free wipes or dry
compressed air.
- Always
ensure that the filter is placed on a clean,
dust-free surface.
Cleaning
Clean
with an IPA cleaner and a dry, lint free cloth
