Lenses
Axicons are optical components which can be used to convert a collimated laser beam into a ring shaped non-diffractive Bessel beam. Holmarc’s axicons are made from UV grade fused silica substrate and are available as uncoated and broadband AR coated.
The ring thickness of the Bessel beam can be calculated from the following formula;
tr = 0.5 * d ........ where d is the diameter of the input collimated beam.
The diameter of the ring at a particular distance can be calculated from the following equation;
Dr = 2 L tan [ ( n - 1 ) α ]
where D is the diameter of the ring at a distance L from the lens, n is the r refractive index of the lens material and α is the axicon angle.
