Imaging channeled spectrograph: a high resolution spectrometer providing multiple simultaneous 2-D monochromatic
Abstract:
An imaging channeled spectrograph (ICS) consists of a Fabry-Perot bandpass filter followed by a wide slit imaging grating spectrograph. This unique configuration combines the 2-D monochromatic imaging of a Fabry-Perot system with the high resolution and comprehensive wavelength coverage of a grating spectrograph. The ICS produces a series of simultaneous, high resolution, nonoverlapping, 2-D monochromatic images uniformly distributed over a large spectral range. This paper describes the ICS optical properties in general and calculates the optical performance of an ICS designed for the proposed NRL spectrocoronagraph.

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
