In some applications, it is desirable to increase the magnification by an additional 50x. With this 2x lens, you can use the Science ETD-201 at magnifications of 16 to 100x. . The working distance is reduced slightly. However, the depth of field is higher at the resulting magnification than when the magnification is increased by simply using another pair of eyepieces. A conversion lens is therefore the accessory of choice for magnifications greater than 50x.
This additional lens is compatible with the following BRESSER microscopes:
