Description
Grey Tape comes in sheets 200mm x 300mm. It
is adhesive backed and can easily be attached to
any smooth, dry surface. It is often stuck to the
back of a retro enclosure.
Grey Tape 5m--40m
The tape comes in rolls 16m x 50mm wide. The tape is
divided into red and silver bands and each have different
refl ective properties. The tape is adhesive backed and
can easily be attached to any smooth, dry surface. It is
often stuck to the back or side of a retro enclosure.

These are multi-faceted IMOS 46mm hexagons.
They can be fi tted together to make up a large
composite array. IMOS Plastic
46mm Retro
30m--100m
The IMOS array shown is made from 14 single
hexagonal retros. They are normaly mounted
on a back plate which is placed in a stainless
steel or FRP enclosure. IMOS Array 50m -- 300m
76 retros are probably the maximum number
that can be economically used as the cost
becomes prohibitive as the number of retros
increases. At path lengths greater than
750m, maintaining the correct alignment
becomes diffi cult.
These retros are enclosed in a PVC, RPF
or stainless steel enclosure. The number of
retros will depend on the type of gas being
measured, the path length and atmospheric
conditions. The window is normally Lexan
but can be changed to a special glass when
measuring some gases. For use outside,
rain hoods and heated enclosures are
recommended to prevent condensation.

This is a gold plated hexagonal retro. It is normally
housed in a plastic or steel box with a Lexan
window. They can also be fi tted together to
make up a large composite array. Gold Plated

75m--150m
The enclosures will vary in size depending on the number of retrorefl ectors and if internal
heating is required. Window materials will depend on the site conditions and the gas to be
measured. Lexan is normally supplied but window glass, boro-silicate and sapphire are
used under specifi c circumstances. Contact Boreal Laser Inc. for more information.
