The AL-DM756 series lenses are designed specifically for our DM756 digital microscopes. The modular design of the microscope allows for various objective lenses to be used to suit changing magnification requirements. Lower magnifications will benefit larger subjects which require a greater field-of-view, while higher magnifications provide improved detail of smaller subjects. While the microscope’s standard 0.7X-5X magnification range is optimal for covering common use-cases, these lenses offer the flexibility to expand the coverage when needed. This kit includes all four lenses allowing the examination of a multitude of specimens with a compact plastic case for storage when not in use. Has a fifth slot available for storing the 1X lens included with the DM756 microscope.
