Plano-Convex Axicon, Conical Lens, AR 250-425nm/370-420nm

Manufacturer's part number :

1-APX-2-UV

Manufacturer Altechna

Altechna

Description :

Plano-convex axicon 1-APX-2-UV series features an AR coating from 250nm to 425nm (Ravg≤0.75%) and from 370nm to 420nm (R<0.5%) with 0° of incidence angle, and an Apex angle from 90° up to  179°. Plano-convex axicon is conical lenses which are used for variety of applications. When followed by a conventional spherical lens, axicons can focus laser light to a ring shape with annular focus. This feature can be used in hole drilling, microscopy and medical applications.
