X-Ray Diffraction Calculator

Calculate crystal plane spacing and diffraction angles using Bragg's Law

Calculation Mode:

X-Ray Wavelength (Angstroms):

Diffraction Angle θ (degrees):

Diffraction Order (n):

Cu Kα: 1.5406 A

Cu Kβ: 1.3922 A

Mo Kα: 0.7107 A

Co Kα: 1.7890 A

Fe Kα: 1.9360 A

Cr Kα: 2.2897 A

2d·sin(θ) = nλ

Where: d = plane spacing, θ = Bragg angle, n = order, λ = wavelength
