In June, astronomers used another VLT instrument called MUSE to observe a visible wavelength of light known as H-alpha, which is emitted when hydrogen falls onto a star or planet and becomes ionized.
Using calculated diffraction gratings with wavelengths less than the visible wavelength of light, Demax's R&D team are able to produce non-saturated colours with non-iridescent tones such as white and pastel blues, pinks and yellows.
PIX4life pilot line aims to offer an open-access manufacturing platform for PICs, specifically targeting life-science applications within the visible wavelength ranges (400-850nm).
While providing effective fire detection for multiple users, it protects personal privacy since no visible wavelength images are transmitted.
The material features the ability to absorb light from low-energy wavelengths and convert it to a selected visible wavelength, heightening visibility in low light conditions such as inclement weather and poorly lit indoor environments.
The Spark-DET-VIS delivers full spectral measurements over the visible wavelength range of 380 to 700 nm.
However, the latter device suffered from constant sensitivity in the visible wavelength region as large as 40% compared to the peak responsivity in the UV-A region.
The Spectrophotometer technology is used in every day industry to either characterise a sample and/or to also provide visible wavelength data for the accurate calculation of colour.
QD Laser also has the potential to extend wavelength lineup by combining with a wavelength conversion technology in visible wavelength regions like 515nm and 555nm for special green laser or 560nm and 590nm for yellow to orange colors.
