Isaac Landa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Probe for transmitting and receiving light from a sample
    Patent number: 5044755
    Abstract: A modular probe is provided to enable introduction of light to a sample to be analyzed by an electro-optical device. The probe of the present invention may include an optical rod or other device for propagating light, an optical barrel which in part surrounds the optical rod, and a sleeve which is provided to attach the probe to a source of light such as a fiber optical bundle. The probe may be fitted with a bidirectional focusing adapter and a reflective tip. A transverse probe is also described.

  • Multiplexer for use with a device for optically analyzing a sample
    Patent number: 4989932
    Abstract: The invention is a multiplexer which enables light to be sent to and received from samples for simultaneous analysis. A multiplexer is described which uses a transverse probe to reflect light at an angle into an optical rod. The transverse probe is selectively rotated to transmit light to a second optical rod. Various numbers of optical rods may be used in the linear mutliplexer. A multiplexer is also described in which a conjugate optical barrel is utilized to selectively reflect light to various probes.
