The highest level of optical quality, operability and stability for polarizing microscopy

Diascopic illumination type

The newly developed high-intensity 50W halogen light source is brighter than a conventional 100W halogen lamp. Low power consumption means less heat generation, thereby reducing the chance of heat-induced focus drift.

Why is 50W brighter than 100W

Brightness is not determined by wattage. Nikon's new light source achieves greater brightness by optimizing the lamp filament size and improving pupil illumination fulfillment by optically expanding the size of the light source. This has resulted in a 50W light source that is brighter than a 100W lamp–about 40% brighter with diascopic illumination*.

  • *With 100x objectives.

Uniform brightness with diascopic illumination

Nikon's unique fly-eye lens employed in the diascopic illumination optics ensure uniform brightness throughout the visual field - perfect for digital imaging.

High-precision rotating stage

The stage is large sized, pre-adjusted, and click-stops in 45° increments. The smooth stage movement allows stable and easy rotation, providing high operability and high-quality polarized images.
Because the stage is supported from the bottom near the optical axis and incorporates steel cross roller guides, it offers excellent stability and durability.

  • Focus stroke has been improved to 30mm, facilitating observation of tall samples.
  • Clamp-type upper limit focusing mechanism makes for easy and safe sample exchange.

Reversed centering quintuple nosepiece

Nosepiece comes with a DIN standard compensator slot to accept various compensators for advanced quantitative measurements. All five objectives are centerable.

Intermediate tube

The intermediate tube incorporates a Bertrand lens as standard, enabling both the observation and capture of conoscopic and orthoscopic images. The Bertrand lens is focusable and centerable. The high precision slider-type analyzer is rotatable for a full 360°.

Objectives for polarizing observation

The industry-acclaimed infinity optics - the CFI60 system -successfully deliver long working distances and high NA and produce tack-sharp aberration-free images.
The episcopic objectives use eco-glass that is totally free of environmentally harmful substances such as lead and arsenic.

Diascopic/Episcopic illumination type

Diascopic/Episcopic illumination type

Both diascopic and episcopic polarizing observations are possible by mounting the LV-UEPI-N universal epi-illuminator. Switching the illumination technique is a simple operation. The epi-illuminator uses the same lamphouse as the diascopic illuminator using the 12V-50W lamp as standard, which provides brighter illumination than a conventional 100W lamp. With an optional universal-type nosepiece and DIC accessories including objectives, episcopic differential interference contrast (DIC) microscopy is also possible.
