0.3x 0.5x 0.7x Reduction Objective Lens

This microscope objective lens features a 48mm threaded mount and offers three fixed reduction magnifications: 0.3x, 0.5x, and 0.7x. It has a metal barrel construction with precision optical glass elements. The lens is compact and designed specifically for trinocular microscopes with standard 48mm thread compatibility. The 0.3x setting maximises working distance — ideal for applications requiring physical clearance between lens and specimen, such as inspection of bulky or uneven samples, soldering, or hands-on manipulation under magnification. Lower magnification also expands field of view, improving spatial awareness during extended observation. Optical glass elements deliver improved brightness and contrast compared to plastic or coated acrylic alternatives, supporting consistent image clarity across the full field without need for frequent refocusing or illumination adjustment. Installation requires only screwing the lens into the microscope’s 48mm threaded port — no tools or calibration needed.
