ABSTRACT:
A beam addressed liquid crystal cell having an absorbing layer adapted to absorb energy in the infrared spectrum while transmitting substantial energy in the visible spectrum is disclosed. In a preferred embodiment the absorbing layer contains the reaction product of bis (dithiobenzil) nickel and a polyamide. This absorbing layer absorbs at least 90% of the gallium arsenide laser wavelengths and at the same time permits transmission in the visible spectrum to be of the order of 80%.
