It is found that practically the laser beam cannot focus on a point, instead, there is a small beam thickness at the focal point. This smallest distance up to which a laser beam can converge is known as the beam waist (w0). It is basically the focal point of a laser beam.

Rayleigh range (ZR) is the distance from the beam waist where the beam radius has increased √2 times its initial value. This is the point at which the area of cross-section is doubled.

Center drilling for fiber optic for X-Focus 365 Lenses Available in .020″, .030″ & .040″ hole sizes Includes 2″ of Green Fiber and 2″ of Red Fiber NOTE: Please allow 5-10 business days for drill service. NOTE: Drilled lenses are non-returnable.

Rayleigh Length (Range) conversion calculator is an online calculator used to calculate the rayleigh length (range) of a laser beam.

Beam Divergence of a laser beam is an angular measure of the increase in the beam diameter or the radius with the distance from the beam waist, from where the beam diverges.

Beam diameter is calculated in terms of beam diameters at two different points far from the rayleigh range and the distance between these points.

Let Df and Di be the beam diameters at two different points away from the rayleigh range and let l be the distance between them. Then beam divergence (θ) is given by,
