Biconvex Lens 12.7mm Diameter 25.6mm Focal Length 750 - 1550nm
SLB-12.7B-25PIR2
Symmetrical biconvex lenses are most useful when dealing with finite conjugate points. This makes them ideal for 1:1 imaging applications or for use in multi-element systems.
◦There are two types of biconvex lenses available; BK7 for use in visible range to infrared wavelength range.
◦BK7 lenses are also available with three types of anti-reflection coatings, visible wavelength range, in the near-infrared range and in the infrared range.
◦Our lenses are listed by outside diameter and focal length to assist your selection according to required specifications.
