LAMBDA DG-4 PLUS & DG-5 PLUS OPERATION MANUAL – REV. 3.05B (20131009)

Increased filter switching speed: The “PLUS” version is able to switch between adjacent
filter positions in 0.5 milliseconds. A switching time of 1 millisecond applies only when
switching between the most spread-apart filters.
Light output is increased by 30% in the “PLUS” series due to the use of larger mirrors
mounted on the switching galvanometers.
New switching power supply automatically allows for operation with voltages ranging
from 110 to 240 VAC, with a frequency range of 50 to 60 Hz.
