The optical attachment also includes at least one loupe orienting feature defined by the visor. | 2020-04-16 |
20200117026 | PARAMAGNETIC GARNET-TYPE TRANSPARENT CERAMIC, MAGNETO-OPTICAL MATERIAL, AND MAGNETO-OPTICAL DEVICE - A paramagnetic garnet-type transparent ceramic characterized by being a sintered body of a terbium-containing composite oxide represented by formula (1) in which the linear transmittance at a wavelength of 1,064 nm at an optical path length of 15 mm is 83% or higher. | 2020-04-16 |
20200117027 | COLOR-TUNABLE TRANSMISSION MODE ACTIVE PHOSPHOR BASED ON III-NITRIDE NANOWIRE GROWN ON TRANSPARENT SUBSTRATE - A system and method providing correlated color temperature-tunable (CCT-tunable) white light using a laser diode(s) in conjunction with a III-Nitride nanowires-based LED element grown on a semi-transparent substrate. The tunability spans across yellow, amber, and red wavelengths and can be implemented by current injection. The current-dependent broad wavelength tunability enables control of wide range of CCT values (intensity, peak wavelength, and spectral coverage). The broad coverage in the yellow-amber-red color regime mimics that of a passive yellow phosphor, while the injection of current into the LED element defines an active phosphor element. The semi-transparent active phosphor element allows direct transmission of light from a laser diode(s) for achieving extreme wide tunability of CCT. | 2020-04-16 |
