The SELFOC Imaging lens is commonly used as an objective lens for small diameter imaging systems where conventional lenses are not suitable due to size limitation. The lens is designed to gather light from an object and form an inverted image at the back surface of the lens. Typical applications include fiberscope (attached to a coherent fiber bundle) and rigid endoscope (attached to a relay lens such as a SELFOC Rod Lens, see next section).

SELFOC Imaging Lenses are specified somewhat differently than SELFOC Micro Lenses (SML). While SML performance is controlled through the lens pitch and gradient constant (√A), Imaging Lens performance is controlled via the working distance (WD) and image quality factors such as resolution and field curvature. For this reason, ILW and ILH lenses can consistently exhibit good image quality despite variations in √A and/or Z (Lens Length).
