A method for producing a liquid crystal device, the method including: assembling two substrates to form at least one liquid crystal cell; and removing material from a first one of the assembled substrates to produce a first region of the first substrate that is thinner than a second region of the first substrate.

Liquid crystal assembly and method of making

Fabry-Perot etalons including a layer of liquid crystal between the reflective surfaces are disclosed. Application of an electric field to the liquid crystal layer changes the effective refractive index of the liquid crystal layer, making the device tunable.

An eyepiece adapter mechanism for providing a quick positive engagement to an interfacing instrument such as a B-styled endoscope. The adapter mechanism comprises a rigid back plate for providing a permanent attachment for the mechanism. A C-clip retainer positioned within a circumferential chamber of the back plate acts as a locking ring under the elastic force of the C-clip material itself to provide a grip around the interfacing instrument when installed into the back plate. An outwardly protruding portion of the C-clip, acting as a lever, releases the interfacing instrument when the level is moved toward a fixed post located a predetermined distance from the lever to facilitate single handed operation. An alternate embodiment provides a quick attach/release adapter without an eyepiece and employing a C-clip retainer.
