The LC 2012 is based on a transmissive liquid crystal microdisplay with 1024 x 768 pixel resolution. It is addressed using a standard HDMI interface and advanced calibration can be performed using the USB interface.
The SLM provides a phase shift of 2π at 532 nm and around 1π at 800 nm. The microdisplay and drive electronics are packaged into a compact box for easy integration into optical setups. The device is delivered with a mounting ring which fits to standard laboratory posts and holders.
LC 2012 SLMs are addressed like an external monitor via a standard HDMI graphics card interface. GUI based calibration and application software (supplied) is used to change geometrical settings, brightness, contrast, and the electro-optical response by applying a new gamma curve. For these advanced callibrations, the USB calibration interface has to be connected via a computer USB port. No additional software or dedicated hardware is required to operate the SLM.
