An optical device includes a stack that includes a first curved optical element stacked with a second curved optical element. The second curved optical element propagates light by total internal reflection. The stack also includes an incoupling diffractive grating that incouples the light into the second optical element and an outcoupling diffractive grating optically coupled to the incoupling diffractive grating through the second curved optical element. The outcoupling diffractive grating directs the light. The first curved optical element has a first refractive index, the second curved optical element has a second refractive index, and the first refractive index is different from the second refractive index by approximately 0.15 to 1.2.

Waveguide for transmitting light

A cell monitoring plate comprises a flat surface on which multiple cell culturing vessels may be stacked. The flats surface has multiple optical imaging systems embedded therein to fully image a cell culture vessels stacked on the plate. Each one of the multiple optical imaging systems provides both illumination and imaging through a single aperture in the surface of the monitoring plate.

A system for disinfecting a medical device is provided. The system includes a light source that generates light having at least one wavelength between about 100 nm and about 500 nm. The system further includes at least one cylindrical optical diffuser disposed in optical communication with at least one interior channel of a medical device, the at least one cylindrical optical diffuser having an outer surface and an end optically coupled to the light source. The at least one cylindrical optical diffuser is configured to scatter guided light through the outer surface to form a light diffuser portion having a length that emits substantially uniform radiation over its length.

The technical solution to the degradation of the adhesive includes both 193 nm scatter light reduction and protective coatings of plasma modified AlFfilms on at least that part of the optical element that is in contact with the adhesive.

Extending the stability of UV curable adhesives in 193NM laser systems

High-power excimer lasers are assembled with individually replaceable optical module subsystems containing consumable optical components. Windows formed in the enclosures of the optical modules incorporate a fluorescent material for converting ultraviolet light scattered from the components of the optical module into visible light emanating from the windows. Changes in the amount or location of the visible light emanating from the windows are interpreted as indications of the degradation in the performance of the optical modules.

The disclosure is directed to a thin-film for use in below 300 nm laser systems that can be applied to a variety of substrate types. The thin film consists of a blocking layer of a selected material and a matching structure, the matching structure consisting of 1-7 layers of a selected material. The blocking layer serves to minimize or eliminate the transmission of below 300 nm laser light into an adhesive that is used to bond the substrate to a holder. The matching layer(s) minimize internal reflectance of below 300 nm laser light from the blocking layer back into the substrate.

The invention is directed to optical elements that are coated with dense homogeneous fluoride films and to a method of making such coated elements. The coatings materials are a high ('H') refractive index fluoride material and a low ('L') refractive index material that are co-evaporated to form a coating layer of a L-H coating material (a co-deposited coating of L and H materials). Lanthanide metal fluorides (for example, neodymium, lanthanum, dysprosium, yttrium and gadolinium, and combinations thereof) are preferred metal fluorides for use as the high refractive index materials with lanthanum fluoride (LaF) and gadolinium fluoride (GdF) being particularly preferred. Aluminum fluoride (AlF) and alkaline earth metal fluorides (fluorides of calcium, magnesium, barium and strontium) are the preferred low refractive index materials, with magnesium fluoride (MgF) being a preferred alkaline earth metal fluoride.
