LDS 6, Optics Housing CD 6

The optics housing CD6
The LDS 6, Optics Housing CD 6 (a optics housing for measuring through a gas channel) is
designed for in situ measurements. It consists of a transmitter and receiver creating a single path
measurement situation. The beam diameter is expanded to about 25 mm in order to improve
performance in high dust load (>1 g/m3) applications.
The transmitter includes a lens and a connection for the optical fiber located in the focal plane
of the lens. The receiver contains a lens, a detector with preamplifier, driver electronics for the
optical return signal, and a 24 VDC to ±15 VDC DC/DC-converter.
The laser light is coupled from the optical fiber in the transmitter to the transmitter lens and
passes through the measurement volume. The lens in the receiver focuses the incoming laser
light on the detector where it is converted to an electrical signal. This signal is amplified and
converted to an optical signal and returned to the central unit LDS 6.
