Overview

Different from plane gratings, concave gratings can make a spectroscopic system without using concave mirrors or similar types of image-forming elements. For this reason, concave gratings are used in a wide range of applications, such as analytical instruments, optical communications, biotechnology, and medical instruments.

This literature explains you about optical applications for spectroscopy using Shimadzu concave gratings. Please specify code numbers of gratings listed below for your inquiry or purchase. The Spectro-Sensor Units integrating slit and detector are also available. Please contact us for further information.

All applications in this document are design samples only. All the data are theoretical and no performance is guaranteed.

Technical terms for diffraction grating and optical mount

Technical terms for diffraction grating and optical mount fig.1Technical terms for diffraction grating and optical mount fig.1
Technical terms for diffraction grating and optical mount fig.2Technical terms for diffraction grating and optical mount fig.2
Groove density N The groove density at the center of the concave grating.
Dispersion D The value obtained by dividing the wavelength range (λ1toλ2) by the detector length L.
Wavelength range λ1toλ2 The optimum wavelength range for the Shimadzu design. Outside this range, aberrations become larger and imaging performance become worse. λ1 and λ2 respectively represent the minimum and maximum wavelength.
Detector length L Length of detector required for application in the above wavelength range.
Blaze wavelength λB The blaze wavelengthλB where the peak diffraction efficiency is expected.
r Entrance path length, the distance from the grating center to the entrance slit A.
r 1' The distance traveled by light of the maximum wavelengthλ1 from the grating center O to the detector surface.
r 2' The distance traveled by light of the maximumλ2 from the grating center O to the detector surface.
r i' The distance along the line perpendicular to the detector surface from the grating surface O to the detector surface
α Incident angle from the grating normal in the counterclockwise direction.
β1 Diffraction angle for minimum wavelengthλ1 from the grating normal in the clockwise direction.
β2 Diffraction angle for maximum wavelengthλ2 from the grating normal in the counterclockwise direction.
βi Angle between the straight line OBi and the grating normal in the counterclockwise direction.
Dimensions W W is the width perpendicular to the grooves.
Dimensions H H is the height parallel to the grooves.
Dimensions T T is the thickness at the center.
Code number Specify a code number when ordering.
