it provides an expansive field of view (field number 25) ideal for initial specimen survey and orientation

This is particularly important at low magnifications where the field of view is large—flat-field correction eliminates the need to refocus when examining features at different positions in the field

providing maximum zoom extension for detailed observation of fine surface features at short working distances

8mm extra-long working distance (ELWD) is a standout feature of this objective—more than double the working distance of standard 50× objectives
