Calibration of an astrophysical spectrograph below 1 m/s using a laser frequency comb.
We deployed two wavelength calibrators based on laser frequency combs ("astro-combs") at an astronomical telescope. One astro-comb operated over a 100 nm band in the deep red (∼ 800 nm) and a second operated over a 20 nm band in the blue (∼ 400 nm). We used these red and blue astro-combs to calibrate a high-resolution astrophysical spectrograph integrated with a 1.5 m telescope, and demonstrate...
متن کاملThroughput & image quality of a MEMS spectrograph — 1 — Calibration concept for the JWST Near - infrared Spectrograph ( NIRSpec ) ST - ECF Instrument
This document provides a discussion of the basic calibration needs and calibration time consumption for the Near Infrared Spectrograph (NIRSpec) on JWST. The current version assumes that slits for multi object spectroscopy will be formed via a microelectromechanical system and that NIRSpec will carry internal continuum and line lamps.

متن کاملOn - Wafer 3 - port S - parameter Calibration October 1997
Preface The objective of the present work is to establish methods for dealing with on-wafer 3-port S-parameter measurements. Error correction methods including calibration and deembedding 1 are discussed and verified experimentally. Chapter 1 presents two basically different methods for making 3-port S-parameter measurements using a 2-port network analyzer. The methods are termed the renormaliz...
متن کاملDesign and Performance of a Planar Array Infrared Spectrograph that Operates in the 3400 to 2000 cm-1 Region
A prototype, no-moving-parts, plane array infrared spectrograph (PA-IR) capable of routine spectral acquisition in the 3400 to 2000 cm21 region has been constructed. The instrument includes a continuous source, Czerney–Turner type monochromator system and an infrared camera that incorporates a 320 3 256 pixel InSb focal plane array detector cooled with liquid nitrogen. PA-IR spectra (;3400 to 2...
