Product Code : Eclipse 50i POL

Brand : Nikon

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.

More About

Eclipse 50i POL

Episcopic DIC (Differential Interference Contrast)

  • By mounting the LV-UEPI universal epi-illuminator and optional universal-type nosepiece and DIC accessories including objectives, Episcopic DIC microscopy is possible.

Reversed Centering Nosepiece

  • Up to five objectives, ranging from 4x to100x can be mounted to the nosepiece and all five objectives are centerable. The nosepiece is also provided with a DIN compliant compensator slot and it accepts various compensators for advanced quantitative measurements.

CFI60 Optical System

  • Nikon's proprietary CFI60 optics provide high NA and a longer working distance. CFI60 optics deliver bright, high-resolution images. Up to five objective lenses can be mounted.

Diascopic and Episcopic Polarization

  • Both Diascopic (transmitted) and Episcopic (reflected) polarization observations are possible by mounting the LV-UEPI universal epi-illuminator.
