Page 4: Part 1. Important Safety Notice
Liquid Crystal Controller Part 1. Important Safety Notice Do Not Open Housing! The LCC25 has no user-serviceable parts. Service should only be performed by trained service personnel. All statements regarding safety of operation and technical data in this instruction manual will only apply when the unit is operated correctly. -
Page 5: Part 2. Product Overview
USB interface, controls the retardance of the LC device. The LCC25 produces a 2 kHz AC square wave with an amplitude that is adjustable from 0 to 25 V The unit features two selectable set points, Voltage 1 and Voltage 2. -

Liquid Crystal Controller Figure 2: A 2 kHz Square Wave Output with 150 Hz Modulation The LCC25 will automatically detect and correct any DC offset in real time to within ±10 mV. This feature increases the life of the liquid crystal device. -
Page 7: Part 3. Setup And Operation
AC Line Voltage The LCC25 is designed to operate at 100 to 240 VAC operation. There is no line switch adjustment to be made. However it may be necessary to replace an open fuse. To do this you must perform the following procedure on page 14, Fuse Replacement. -
Page 8: Setting The Output
0.5 to 500 Hz, and any duty cycle, but must be 0 and 5 Volts to trigger the flip. The output from the LCC25 will be modulated based on the input frequency with Voltage 1 being the high and Voltage 2 being the low. -
Page 9: Computer Controlled Operation
Liquid Crystal Controller Computer Controlled Operation The LCC25 may also be controlled by a command line language through the USB port. This is offered to enable operation through a terminal interface or for those who may want to write their own program to control the unit. The command language is described below. - Page 10 Set voltage. Locks out use of buttons Locks out buttons on from panel.

The enclosure may be cleaned by wiping with a soft damp cloth. There are no serviceable parts in the LCC25 and no reason to open the unit. If you suspect a problem with your LCC25 please call Thorlabs and technical support will be happy to assist you. -
Page 15: Troubleshooting
Thorlabs technical support for assistance. Note: The LCC25 circuitry has been designed to monitor and correct the DC offset in real time. This will increase the life of the Liquid Crystals. For any unforeseen reason DC offset is detected above the ±10 mV limit enabling the DC OFFSET ERROR to appear. -
