2 mm Cemented Triplet Lens / Three-Element Achromatic Lens
Micro Achromatic Triplet Lenses are precision-cemented from three optical glass elements (typically low-index crown + two high-index flint or custom combination) with an outer diameter of 2.0 mm, specially designed for ultra-compact endoscope objectives, borescope probes, and micro-imaging relay systems. The three-element design corrects axial and lateral chromatic aberration as well as spherical
