A multilayer coating systems suitable for use as optical interference filters in lighting systems, for example, halogen lamps. Such an optical interference filter contains alternating layers of a high refractive index material and a low refractive index material. The high refractive index material consists of niobia, titania, and incidental impurities and contains either about 25 to less than 50 mol % titania and the balance niobia and incidental impurities, or contains about 60 to about 80 mol % titania and the balance niobia and incidental impurities.

Optical interference filters, and filament tubes and lamps provided therewith

Example embodiments relate to a method and apparatus for reducing electrostatic deposition of charged particles on wetted surfaces that are exposed, periodically or substantially continuously, to high velocity fluid flow within a coolant flow path in a nuclear reactor. The method may include depositing a first or base dielectric layer and a second or outer dielectric layer on a conductive surface that forms a portion of a high velocity flow path to attain the apparatus. The first dielectric layer material is selected to provide improved adhesion and insulation to the conductive surface and the second dielectric layer material is selected to provide suitable adhesion to the first dielectric layer and improved corrosion and/or mechanical resistance in the anticipated operating environment.

Dielectric coating for surfaces exposed to high temperature water

Disclosed is a method for reducing electrostatic deposition of charged particles on wetted surfaces that are exposed, periodically or substantially continuously to high velocity fluid flow within a coolant flow path in a nuclear reactor. The method includes depositing a first or base dielectric layer and a second or outer dielectric layer on a conductive surface that forms a portion of a high velocity flow path. The first dielectric layer material is selected to provide improved adhesion and insulation to the conductive surface and the second dielectric layer material is selected to provide suitable adhesion to the first dielectric layer and improved corrosion and/or mechanical resistance in the anticipated operating environment.

An electric lamp assemblyfor emitting near infrared radiation includes a reflector housingand a lamp vesselpositioned within the reflector housing. A source of illuminationis enclosed within the lamp vessel. A continuous multi-layer interference filmon an exterior surfaceof the lamp vessel transmits near infrared radiation within the range of 850-1100 nm and is substantially non-transmissive towards visible radiation.

Lamp for night vision system

An optical interference coating for reflecting infra-red radiation and transmitting visible light. The coating comprises alternating layers of high index of refraction material and low index of refraction material. As the total number of layers increases, the ratio of high index of refraction material to low index of refraction material must also increase.

Stress relief mechanism for optical interference coatings

An interference coating ( ) for reflecting both visible light and a portion of the region of the infrared spectrum is disclosed. The coating includes a dichroic structure of a plurality of layers of a material having a low index of refraction and a plurality of layers of a material having a high index of refraction. The coating has an average spectral high reflectance of at least 80% for wavelengths in the visible light section of the electromagnetic spectrum and of at least 50% for wavelengths in a portion of the infrared section of the electromagnetic spectrum at least 150 nm wide.
