“The detectors are easy to set up due to their high dynamic range. They can handle low signals but do also not switch off and perform well with high signals. This makes it very user friendly to set up the microscope. The photon counting mode is a highly appreciated function. The high precision and simple adjustment and high flexibility make the FV4000 a very valuable tool for imaging facilities with users of different experience levels and varying complexity in their imaging experiments.”

Breakthrough SilVIR™ Detector Technology: The New Gold Standard

Our advanced, silicon-based SilVIR™ detector makes it easier than ever to acquire precise, reproducible data.

The detector combines two advanced technologies—a silicon photomultiplier (SiPM) and our patented* fast signal processing design.

  • High dynamic detection enables the system to acquire weak and strong fluorescence signals in one image with good linearity and quantify the number of photons for better image analysis.
  • Widest available spectral detection wavelength (400–900 nm) enables you to use visible to near-infrared fluorescence dyes and capture data with high spectral efficiency**.
  • Ultra-low noise translates to ultra-dark backgrounds, so even very weak fluorescence stands out.
  • Unlike old detector technologies, the SilVIR detector's sensitivity remains constant over time for consistent, reproducible experiment data.

HeLa cells labeled by MitoView 720. XYZT imaging by 1K resonant scanner for 30 min.

Time-lapse imaging is easier with smart features:

  • Capture every moment of live cell dynamics: resonant scanner can acquire high-resolution images over a wide area
  • Minimal phototoxicity: the scanner’s short pixel dwell time reduces the time the focused laser beam rests on a single spot
  • Better signal-to-noise ratio: the SilVIR detector’s high sensitivity produces higher quality images at higher speeds
  • Greater precision: rolling average processing maintains qualifications and time resolution

Reproducible Image Data Between Users and Systems

The SilVIR detector has less sensitivity loss over time compared to previous-generation detector technologies. With our laser power monitor (LPM) and TruFocus™ Z-drift compensator, achieve reproducible images under consistent conditions. Different users on different days can acquire the same precise images using the same settings. Even the images acquired by different FV4000 microscopes can be compared and discussed using the same photon number intensity scale.

To further enhance reproducibility, the Microscope Performance Monitor makes it easy to check the system’s laser power, detection sensitivity, and optical performance, helping ensure that your FV4000 microscope is functioning at a consistent and high level.

Award-Winning Technology for Award-Winning Research

The FV4000 system's optical elements have a high transmission from 400 nm to 1300 nm, including the galvanometer and resonant scanner, which are coated in silver rather than aluminum.

Our award-winning X Line™ objectives are corrected for chromatic aberrations between 400–1000 nm. They also have a higher numerical aperture, excellent flatness, and very high transmittance from UV to NIR, increasing the multiplexing capabilities.

For improved colocalization reliability, our specialized A Line™ (PLAPON60XOSC2) oil immersion objective (ne~1.40) significantly minimizes chromatic aberration for strict colocalization analysis.

Quickly and easily capture high-resolution 3D images of thick samples.

Maximize Depth, Time, and Image Quality

  • Penetrate deeper into tissue with NIR’s longer wavelength and the SilVIR detector’s wide dynamic range and sensitivity.
  • Image deeper with less scattering and absorption since light scattering compounds—like melanin and heme—absorb less light between 700–1500 nm.
  • Image deeper than what’s possible with visible lasers using the 685 nm, 730 nm, and 785 nm diode lasers on the FV4000.
  • High NA silicone objectives minimize spherical aberration.
  • Silicone oil does not dry out at room temperature, enabling more efficient time-lapse imaging experiments.
  • Acquire stunning 3D images of thick samples using TruSight™ deconvolution.

Precise Dynamics of Live Cells with Less Damage

Typically, using longer wavelengths for fluorescence excitation for shorter periods of time is better for overall sample health. Using less phototoxic light means you can image for longer periods, enabling you to obtain more consistent and reproducible data from live cell imaging experiments.

The FV4000 system not only provides gentle time-lapse imaging via the 685 nm, 730 nm, and 785 nm lasers, but it also features a dedicated TruFocus Red Z-drift compensator to maintain the focus position. This upgraded TruFocus Red unit supports a larger range of wavelengths and is compatible with a wide range of objectives, including our high-performing X Line™ and A Line™ series.

“The New FV4000 will allow for faster imaging + better preservation of the sample…and will allow better reproducibility.”

Clear Images at Depth

Use our silicone immersion objectives with the FV4000 microscope and achieve clear images of features and structures deep within your sample. Silicone oil has a refractive index close to that of live cells or tissue, greatly reducing the spherical aberration as compared to air, water, or other oils. With less aberration, you can achieve clearer images of your sample at depth. And silicone immersion oil does not dry out at 37 ℃ (98.6 °F), making it effective for long-term time-lapse imaging.

AI Solutions for Confocal Microscopy

Stunning, Data-Rich Images in Less Time and with Less Effort

Get better images in less time and with less effort. TruAI™ denoise technology takes the already low-noise images from the FV4000 and reduces noise to ultra-low limits for stunning, data-rich resonant images.

To speed up image analysis, you can pretrain an AI model so that the system can automatically segment your image data, greatly reducing the workload of this often time-consuming manual process. Then, TruAI technology further streamlines the analysis so that you can get your data quickly.

Where Innovation Meets Imaging Excellence

Improve your resonant scanner image quality by incorporating TruAI noise reduction. Although resonant scanner images are effective in capturing cellular dynamics at high speeds with low damage, this usually causes a compromise in the S/N ratio. TruAI noise reduction can improve these images without sacrificing time resolution using pre-trained neural networks based on the noise pattern of the SilVIR™ detectors. These pre-trained TruAI noise reduction algorithms can be used for on-the-fly processing as well as post processing.

Faster, Easier Image Analysis

Image analysis requires data extraction using segmentation techniques based on intensity value thresholds. However, this can be time-consuming and is affected by the sample conditions.

TruAI image segmentation using deep learning helps streamline image processing and minimize sample variables for more accurate image analysis. It enables you to segment superior performance with weak fluorescence fluorescence images or tissues that are usually difficult to extract using the simple thresholding method.

Configurations

The FV4000 microscope is engineered to be modular, making it easy for you to configure the system based on your applications and budget. You can start with a standard FV4000 and easily upgrade to multiphoton imaging by adding the MPE module as your research changes.

One Platform for Your Research Needs

Multiphoton and single-photon combination imaging in one sample is also possible. The FV4000MPE microscope is capable of second and third harmonic generation imaging, so different researchers or users can make the most out of the system. If your research requires a custom setup, the microscope’s modularity and optional ports enable you to customize the system to add extra lasers, cameras, detectors, and more.
