Design and verification of a flat-field aberration-corrected concave blaze grating for hyperspectral imaging

Using an ultra-compact optical system to improve lateral flow immunoassay results quantitatively

“…The spectral module, manufactured by SpectroChip, Inc., accurately determined the locations of emergent and incident light paths by using the equation for diffraction grating, as expressed by Eq. (1) , where m is an integer that denotes the diffraction order, λ is the wavelength of the light source, d is the spacing between grating fringes, α is the angle of incidence, and β is the angle of emergence [ 31 , 32 , 33 ]. …”
