| The
Reflector R reflects a luminous ray back towards the source which emitted
it. It thus allows the creation of a reflecting optical barrier with V3
or V5 optical - laser barriers.
DELTA offers a wide range of reflectors to meet the different application
requirements :
- Ambient temperature as high as 400 °C / 750 °F
with water cooling and 250 °C / 480 °F without water cooling.
- Designed for harsh environments.
- Air-purging to keep dust clear from the reflectors.
- High eficiency reflector: R430: distance up to 30 m
with optical barrier V3 and 50 m with laser barrier V5
Principle
A prism reflector reflects light back along the same axis
as the emitting light, independent of the angle of emission.
The angle of emission must not, however, exceed 15°.
Ambient temperature
The maximum allowable temperature depends on the type of prism. The
attachment of a water cooled base allows for use in higher ambient temperatures.
Warning : A plastic multi-prism reflector may be deformed by intense infrared
radiation, even at low ambient temperatures. It is therefore advisable
not to place a plastic reflector in close proximity to a strong IR source
(e.g. hot product, furnace).
