2X Barlow Lens for 23.2mm Microscopes

Engineered for reliability in routine biological microscopy, this 2X Barlow lens fits securely into any microscope using the 23.2mm eyepiece interface — the international benchmark for biological instruments (0.91 inch). Its all-metal body ensures rigidity and resistance to impact or thermal expansion, while its calibrated 22mm insertion depth guarantees correct placement in the optical path. Delivers uniform 2× magnification across a 15mm field of view, supporting both Huygens and wide-angle eyepieces. Designed specifically for upright/inverted biological microscopes; incompatible with stereo microscopes (30mm interface). Includes only the lens — no packaging extras or documentation beyond basic safety notes.
