Eclipse 50i POL Polarizing Microscope

A compact polarizing microscope that balances optical performance and ease of use

With its small footprint, the Eclipse 50i POL is a basic polarizing microscope that offers powerful microscope optics and comfortable operation in an affordable package. Available in diascopic and episcopic illumination types, the 50i POL features a newly designed illumination system that provides greater brightness than any microscope in its class.
