Outstanding optical performance, perfect for a wide variety of imaging applications and polarizing techniques 
Diascopic illumination type
The newly developed high-intensity 50W halogen light source is brighter than a conventional 100W halogen lamp. Low power comsumption 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*.
Nikon's unique fly-eye lens employed in the diascopic illumination optics ensure uniform brightness throughout the visual field - perfect for digital imaging. Conception of "fly-eye" optics  
Improved body shape realizes higher robustness. Due to the newly designed stage mount, the LV100POL achieves double rigidity compared to the conventional model. 
Nosepiece comes with a DIN standard compensator slot to accept various compensators for advanced quantitative measurements. All five objectives are centerable. 
The intermediate tube incorporates a Bertrand lens, enab both observation and capture of conoscopic and orthoscopic images. 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. 
CFI P Achromat objective series
（for diascopic illumination）
CFI LU Plan Fluor EPI P objective series （for episcopic illumination）
- 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.
Back to top Diascopic/Episcopic illumination type
Both diascopic and episcopic polarizing observations are possible by mounting the LV-UEPI 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. 尼康LV100 POL |
