Fluorescence Microscopy with Nikon Systems: An In-Depth Guide

Q: What makes Nikon’s Noise Terminator different from standard filter cubes?

Nikon’s Noise Terminator technology directs stray excitation light away from the detection path, greatly improving the signal-to-noise ratio and making weak fluorescence signals easier to detect. Standard filter cubes do not actively manage stray light in this way and therefore offer lower contrast, particularly with dim samples.

Q: How does the NSPARC detector reduce photobleaching?

The NSPARC detector uses an array of 25 ultra-low-noise detectors that collect photons very efficiently. Because more signal can be obtained at lower excitation power, users can reduce laser intensity and exposure time, which in turn reduces photobleaching and phototoxicity while maintaining high image quality.

Q: What is the advantage of long-working-distance water-immersion objectives?

Long-working-distance water-immersion objectives provide a wide, flat field of view and sufficient space between the lens and specimen to accommodate thick samples such as tissues and organoids. Water immersion closely matches the refractive index of biological samples, reducing spherical aberration and improving resolution and contrast at depth. Auto water dispensers can maintain immersion for long-term imaging.

Q: Can I upgrade my existing Nikon microscope to digital imaging?

Yes. Many Nikon microscopes can be upgraded with Digital Sight cameras to provide high-resolution image capture and live streaming. The Digital Sight 100 camera, for example, offers 17.7 megapixel resolution, 12-bit color depth, and live imaging at up to 60 frames per second. For fully integrated digital viewing, the ECLIPSE Ui microscope combines a built-in camera and PC.

Q: How do NIS.ai modules improve fluorescence images?

NIS.ai modules use artificial intelligence to automate common fluorescence image-processing tasks. Clarify.ai removes blur, Convert.ai predicts missing channels, Enhance.ai restores underexposed images, Segment.ai identifies and segments complex structures, and Denoise.ai reduces shot noise. These tools improve image quality and streamline analysis without requiring programming skills.

Q: How can I combine phase contrast and fluorescence on the same microscope?

Nikon’s Ti2 microscope platform uses an external phase-contrast system that does not require phase rings in the objectives. This allows the same high-NA objectives to be used for both phase contrast and advanced fluorescence techniques, such as TIRF and weak-signal imaging, without switching lenses. Users can quickly change imaging modes while maintaining the same optical configuration.

Q: What training or support does Nikon provide?

Nikon provides support through Nikon BioImaging Labs, which offer access to advanced instruments, contract imaging services, and expert guidance. Nikon also maintains online resources including step-by-step guides, tutorials, and e-learning courses. Independent educational content from sites such as FrediTech further helps users understand microscopy principles and equipment selection.

Q: What is the difference between N-SIM S and N-SIM E?

Both N-SIM S and N-SIM E are structured illumination super-resolution systems that approximately double the resolution of conventional widefield microscopy. N-SIM S is a high-speed system that can acquire images at up to about 15 frames per second and allows switching between confocal and super-resolution imaging on the same platform. N-SIM E provides similar lateral resolution of around 115 nm at a lower cost, but with slower acquisition speeds.

Q: How do I choose the right Nikon fluorescence microscope for my lab?

Choosing a Nikon fluorescence microscope starts with defining your core applications, such as routine diagnostics versus advanced research, the number of fluorophores you need to image, required resolution and throughput, and the typical sample thickness. The Ci series is suited to clinical work, the Ni series to advanced research applications, and the Ti2 series to live-cell imaging and high-content screening. Frameworks such as FrediTech’s 'Choosing Your Lab Equipment' guide can help structure decisions around performance, budget, and long-term service needs.

Foundations of Fluorescence Microscopy

How Fluorescence Works

Fluorescence microscopy exploits the Stokes shift – the difference between a fluorophore’s absorption and emission wavelengths. When a sample is illuminated with specific excitation light, fluorophores absorb photons, rise to an excited state, lose some energy through vibration and then emit photons at a longer wavelength. According to Abcam’s overview, the process involves three stages: excitation, energy dissipation and emissionabcam.com. The emitted light is detected against a dark background, providing high contrast compared with bright‑field imagingabcam.com.

Key components of a fluorescence microscope include:

Light source – Traditionally mercury or xenon lamps, but modern systems use LEDs or lasers for precise wavelength selection and long lifelabx.com.

Filter cubes – Each cube houses an excitation filter, dichroic mirror and emission filter. The dichroic mirror reflects excitation light into the objective and transmits the weaker emission toward the detector. Nikon’s Noise Terminator filter blocks direct residual stray light and dramatically improves the signal‑to‑noise (S/N) ratio by absorbing stray photonsmicroscopyu.com.

Objectives and optics – High‑numerical‑aperture lenses focus light onto the specimen and collect emitted photons. For fluorescence imaging of thick specimens, Nikon’s long‑working‑distance Plan Apochromat Lambda objectives provide a wide field of view and exceptional optical performancemicroscope.healthcare.nikon.com.

Detectors – Cameras or photomultiplier tubes convert light into electronic signals. Nikon offers high‑resolution Digital Sight cameras with 17.7 megapixel sensors and 12‑bit color depth for crisp, high‑dynamic‑range imagesmicroscope.healthcare.nikon.com.

Fluorescence Techniques

Fluorescence microscopy encompasses multiple techniques:

Wide‑field (epifluorescence) microscopy illuminates the entire field of view and is ideal for bright, thin specimens.

Confocal microscopy uses a pinhole to reject out‑of‑focus light, creating optical sections and reducing blur. Nikon’s NSPARC detector array provides low noise and a large field of view, enabling high‑throughput confocal imaging with lower excitation power and less photobleachingbiocompare.com.

Structured illumination microscopy (SIM) projects patterned light onto the specimen and computationally reconstructs images with twice the resolution. Nikon’s N‑SIM S achieves approximately 115 nm lateral resolution and 15 frames per second, allowing researchers to switch from confocal to super‑resolution mode on demandmicroscope.healthcare.nikon.com. The N‑SIM E offers similar resolution and an affordable entry pointbiocompare.com.

Total internal reflection fluorescence (TIRF) selectively illuminates a thin region near the coverslip, ideal for visualizing membrane dynamics. Nikon’s objectives with high numerical aperture (e.g., CFI Apochromat TIRF 100× oil) deliver optimal TIRF performancemicroscope.healthcare.nikon.com.

Multiphoton microscopy excites fluorophores using infrared photons that only interact at the focal point. Nikon’s AX R MP system pairs multiphoton excitation with an array detector for deep tissue imaging with minimal photodamageprnewswire.com.

Selecting Fluorophores and Filters

Choosing fluorophores with distinct excitation and emission spectra prevents channel overlap. Nikon’s catalog of fluorescence filter cubes includes longpass and bandpass options to accommodate diverse probes. These cubes achieve 93 % – 97 % transmission and high fluorescence acquisition efficiencymicroscope.healthcare.nikon.com. A sharp cutoff between excitation and emission wavelengths reduces bleed‑through, while precise manufacturing eliminates image shifts when overlaying multiple channelsmicroscope.healthcare.nikon.com. Step‑by‑step selection involves:

Identify probes with minimal spectral overlap.
Select filter cubes matching each fluorophore’s excitation/emission peaks.
Mount filter cubes in the fluorescence turret (up to four cubes on Ci series, six on D-FL attachments)microscope.healthcare.nikon.com.
Verify performance using calibration slides and adjust exposure to avoid saturation.
