Buying Guide

Match mount and standard

Confirm the eyepiece or objective fits your microscope’s mount (23.2mm, 30mm, DIN, C-mount) to avoid incompatibility

Choose the right magnification

Select eyepieces and objectives that combine to give usable total magnification for your tasks—low power for overview, 40x–100x for detail

Prefer achromatic for brightfield

Achromatic objectives correct color fringing and are a practical choice for general brightfield imaging and education

Widefield eyepieces for comfort

Widefield eyepieces increase the apparent field of view, reducing eye strain during extended observation sessions

Consider digital/CMOS compatibility

Choose C-mount lenses or adapters if you plan to attach a camera for digital microscopy or industrial imaging
