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:
