Overview: A rod lens is a cylindrical lens which has the geometrical form of
a cylinder with polished on the circumference and ground on both
ends. Optical performance is similar to a cylinder lens. Rod lenses
can be used, for example, for collimating a divergent beam in one
dimension or for focusing light to a line. There are also half-rod lenses, which are rod lenses cut into two
equal pieces. Rod lenses are available with different optical materials. N-BK7
and UV fused silica substrates are available for a variety of UV,
visible and NIR applications. Rod lenses can have diameters of a few millimeters, but there are
also cylindrical microlenses with substantially smaller diameters.
Small-diameter rod lenses are frequently used as fast-axis
collimators for diode bars. Star Optic offers custom sizes, variations in polishing/ ground
surfaces and additional coatings are available upon request. We
look forward to your inquiry.
