  • Mid-wave infrared lens system with liquid optical element
    Patent number: 5687022
    Abstract: A lens system with a liquid optical element is for use in the mid-wave infrared from 3.0 micron to 5.0 micron wavelength is described. Using a liquid optical element which is highly transmissive in the 3.0 micron to 5.0 micron waveband of interest in conjunction with a solid material which is also highly transmissive in that waveband provides a lens design with very good optical performance which is less expensive and which is much lighter in weight than an all solid design of the same optical performance.
