Abstract: Instruments and methods are disclosed which measure absolute energy and irradiance of UV light sources. The response curves of exemplary optical stacks of the radiometry instruments are substantially rectangular with steep transitions at the cutoff frequencies. Angle of incidence (AOI) control in combination with one or more interference filters in the optical stack enable the full optical stack to produce repeatable and accurate measurements. Inverse response filters are disclosed for leveling optical stack response.

Abstract: The present application discloses device and system embodiments that address mobile device integration considerations for various categories of UV sensors, including cameras, photodiodes, and chemical sensors. The UV sensors may use the functionalities of the existing in-built sensors in conventional mobile devices, and/or integrate additional components specific to UV sensing. By optimally positioning the sensors, UV sensing and other collateral functionalities (e.g., charging a photovoltaic cell integrated with the mobile device) can be realized in parallel.

Abstract: A sealing system (20) for an optical sensor of a turbine engine that diverts and exhaust seal leakage away from the seal (22, 24) to prevent ingestion of humid air through the seal (22, 24) is disclosed. The sealing system (20) may include inner and outer optical housings (26, 28) with first and second seals (22, 24) positioned there between separating inner and outer optical housings (26, 28) radially. The sealing system (20) may include one or more leakage manifolds (30) positioned between the first and second seals (22, 24) and containing one or more manifold rings (32). The manifold ring (32) may be positioned between and in contact with the first and second seals (22, 24) enabling the first and second seals (22, 24) to form a double seal. The manifold ring (32) may also be configured to capture leakage air that has seeped past the first seal (22) and exhaust that leakage air through one or more exhaust vents (34) in the outer optical housing (28) before leaking through the sealing system (20).

Abstract: An image-capturing and light-sensing optical apparatus has both of an image capturing function and a light sensing function. The image-capturing and light-sensing optical apparatus includes a first optical lens module, a second optical lens module and a casing. The casing has a first opening. The first optical lens module includes a first optical lens and a first optical sensor. According to the working distance or the equivalent focal length of the first optical lens module, the size of the first optical lens and the size of the first optical sensor, the maximum field of view is acquired. Consequently, the size of the first opening is determined, and the casing is slim. Under this circumstance, the image-capturing and light-sensing optical apparatus complies with the purpose of miniaturization.
