Nikon Polarizing Microscopes LV 100 Pol

LV 100 Pol

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.

Key Features

Uniform brightness with diascopic illumination

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

High-precision rotating stage

The stage is large, 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.

Objectives for polarizing observation

The industry-acclaimed infinity optics - the CFI60 system - successfully delivers long working distances and high NA to produce sharp aberration-free images. They employ an eco-glass that is manufactured with no harmful substances such as lead and arsenic.

The episcopic objectives are from the newly developed CFI60-2 series and produce sharp aberration-free images regardless of magnification.

  • 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 center-able.

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°.

The objectives use eco-glass free of environmentally harmful substances such as lead and arsenic.

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 12V-50W lamphouse as the diascopic illuminator, providing 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.
