AmScope 2.0X Barlow Lens For SF Series Stereo Microscopes (54mm)

This is a set of 4 common Barlow lenses for our SM and SW series stereo microscope heads. The included magnifications are: 0.5X, 1X, 1.5X, and 2X. The 0.5X lens will reduce the objective magnification by half, increasing the field-of-view and the working distance. The 1X lens is used primarily as protection for your microscope's objective lenses from smoke and abrasive materials while performing tasks such as soldering. The 1.5X and 2X lenses increase the overall magnification by their respective amounts, as well as decrease field-of-view and working distance. They all use a 48mm (1-7/8") mounting thread.

This is a brand new 0.7X auxiliary objective (Barlow) lens for ZM series stereo microscopes. It extends the working distance and field view of the microscope and cuts magnification power by 0.7 times. This lens comes with a 1-7/8" (48mm) mounting thread and goes with most stereo microscopes. It is the ideal lens for ZM series stereo microscopes.

This is a brand new 0.5X Barlow (auxiliary objective) lens for stereo microscopes. It offers an 8.7" (220mm) working distance, doubles the field-of-view of your microscope, and cuts magnification power by half. This lens comes with a 2-1/8" (54mm) mounting thread and goes with SF series stereo microscopes.

The ZM20 auxiliary lens will double the magnification of our SM, SW, and ZM series stereo microscopes. A side-effect of the increased magnification is a reduction of working-distance. The lens mounts to the bottom of the microscope's objective housing using a 48mm thread. The lens provides a 48mm mounting surface for ring-lights.
