The ESIS-II mission aims to capture high-speed “snapshot” images of the Sun’s transition region and corona. To achieve this, the instrument utilizes a slitless spectrograph design that requires ...

The toughest job a highbrow machinist can tackle is to make a diffraction grating. The end result does not look like much: just a piece of glass coated with a film of aluminum in which thousands of ...

Abstract: This paper reports an optical cantilever that can measure displacement with high resolution by using an interference pattern and the sampling moiré method. The proposed cantilever has a ...

A wide mode-hop-free and narrow-linewidth tunable laser diode source employing a Littman-Metcalf configuration with a diffraction grating is developed. We conducted a series of experiments to evaluate ...

Researchers from the Institute for Materials Research at Tohoku University, in collaboration with the Japan Atomic Energy Agency and the RIKEN Center for Emergent Matter Science, have identified a new ...

A diffractive optic creates two DUV beams, which are focused and interfered on a sample surface (diamond) using a 4f imaging system to generate a microscopic sinusoidal excitation profile. Credit: ...

Quantum cascade lasers (QCLs) in the mid-infrared (MIR) hold significant potential for widespread applications in both military and civilian contexts. However, the utility of present single-chip QCLs ...
