The recently proposed optical elements containing semitransparent wavelike films embedded into the transparent material are investigated. Such do not distort a wave transmitted through them. Novel can be fabricated using well-known embossing methods. Their possible applications discussed. holographic used for color holography, augmented reality wearable glasses, as beam combiner head-up display...

The methods of production electricity from renewable sources are currently highly researched topics. reason for this is growing social awareness regarding the environmental impact traditional energy technologies. main aim study to describe results using silicon cell technology and dye concentrator in a single system. experiment presented paper was conducted laboratory environment form tinted lu...

We herein present an autopsy case of fatal methemoglobinemia due to suicidal ingestion of sodium nitrite. A man in his 30s who had exhibited mild depression was found dead in his house. A glass containing a white turbid solution and a suicide note were found on the table near the decedent. At autopsy, the lividity of the face and back was greenish gray, and the blood was tinted a chocolate brow...

PURPOSE To compare contrast sensitivity and color vision in patients in whom blue-light filtering and non-yellow-tinted intraocular lenses (IOLs) were implanted. SETTING Refractive Surgery Unit, Hospital NISA Valencia al Mar, Valencia, Spain. METHODS Forty eyes of 20 patients were enrolled in a blue-light filtering fellow-eye control study; patients were implanted with a yellow-tinted IOL (...

PURPOSE To investigate patterns of functional magnetic resonance imaging (fMRI) activation during sentence reading before and after wearing color-tinted lenses. METHODS A total of 15 Meares-Irlen syndrome patients with a mean age of 23.4 years (range, 13 to 42 years) with no history of neurological or psychiatric disorders were scanned using a 3T MR scanner (Siemens, Tim-Trio, Germany). Each ...

Tinted and colour-neutral semitransparent organic photovoltaic elements are of interest for building-integrated applications in windows, on glass roofs or on facades. We demonstrate a semitransparent organic photovoltaic cell with a dry-laminated top electrode that achieves a uniform average visible transmittance of 51% and a power conversion efficiency of 3%. The photo-active material is based...

Increasingly, automobile designers are utilizing tinted glasses for concept cars, specialty models, or to differentiate their vehicles. The objective of this study was to assess whether alternating different tinted windshields would affect aging drivers' visual acuity and glare response. Two commercially available windshields (bluish and greenish with same transmittance) were compared. The test...
