Figure 3 Horizontally and Vertically Mounted LCC3111H Noise Eaters. Note
the direction of the input polarization indicated by the double arrow.
4.2. Power Supply
The noise eater operates with 12 V DC power. We recommend using the AC/DC
power supply that is included with the noise eater for best performance.
4.3. Powering ON the Noise Eater
When the noise eater is connected to the power supply, it automatically powers
on. There is no additional power switch.
4.4. Beam Centering
For best performance of the noise eater, it is recommended that the beam is well
centered in the input aperture. Due to the optical path inside the noise eater, the
output beam will be shifted down by 1.0 mm if the noise eater is mounted
vertically as shown in Figure 3 (right). Similarly, the output beam will be shifted
sideways by 1.0 mm if the noise eater is mounted horizontally as in Figure 3
(left).
