Nikon introduces the ECLIPSE Ni-L Upright Microscope

Achieve more natural observation with a balanced LED light source

May 23, 2023

ECLIPSE Ni-L Upright Microscope

TOKYO - Nikon Corporation (Nikon) announced the release of the ECLIPSE Ni-L upright microscope which features specially balanced LED illumination with properties similar to natural light. This results in more accurate displays of the original color rendition of the specimen, making it particularly effective for observation of pathological specimens and cells.

Product Name ECLIPSE Ni-L Upright Microscope

Development Background

As commonly used brightfield microscopes transition away from halogen bulbs to LED light sources, this gives rise to images with blueish hues due to the unnatural color temperatures of many LED light sources. Nikon has developed the ECLIPSE Ni-L upright microscope equipped with a more balanced natural color LED light source that renders truer microscope images.

Main Features

1. High color reproducibility by adoption of high color-rendering LEDs

Since the color of LED light is stable, color information and images can be achieved with high color reproducibility when imaging specimens using microscope digital cameras and NIS-Elements imaging software. This reduces the need to correct color by color management software and contributes to improved accuracy of image analysis and AI learning.

2. Significant reduction in environmental impact

LED light sources boast a lifespan of approximately 25 times greater*1 than that of halogen light sources, contributing to the reduction of waste materials associated with replacement. Their low power consumption also contributes to the reduction of CO2 emissions within our environment. LED light sources also significantly reduce the maintenance load in terms of light source replacement and potential down time.

3. Eliminates the need to utilize color balance filters

For microscopes using a halogen light source, color adjustments are made using NCB (Neutral Color Balance) filters to correct for the varied color temperatures normally experienced with this technology. Color balanced natural light LEDs eliminate the need to use these filters and therefore also eliminates the risk of human error, such as forgetting to attach or detach color correction filters during critical imaging sessions.

4. Space-saving compact design

Microscopes using a halogen light source are designed with externally attached lamp housings in order to facilitate regular light source replacement. The ECLIPSE Ni-L, due to longer life expectancy of LED light sources, has the illumination built-in resulting in an overall size reduction of 150 mm. This increases the flexibility to choose the most effective observation location to suit your needs.
