Reflecting BARRIER Presentation 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 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. 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°.

Technical characteristics 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).
