High-Sensitivity, High-Resolution Deep Multiphoton Imaging

The FVMPE-RS multiphoton microscope employs advanced technology and optical design to enhance sensitivity and resolution during deep imaging.

  • Broad 400 nm to 1600 nm spectral transmission window efficiently delivers near-infrared excitation without compromising short wavelength detection
  • Large-area detection path collects more emission signal, especially large-angle scattered photons
  • TruResolution objectives offer automated spherical aberration compensation to increase brightness and resolution, revealing fine details at every plane within a deep image stack

High-Speed Imaging for Fast, Dynamic Cellular Processes

High-speed resonant scanning and high-resolution linear scanning are standard.

  • Full frame imaging at 30 frames-per second (fps) reduces motion artifacts during in vivo and live cell imaging
  • 438 fps maximum imaging speed enables you to capture rapid, dynamic phenomena, such cell transport during blood flow and calcium signaling events in neurons and other cells

Multiwavelength Excitation for Broader Spectral Coverage

The FVMPE-RS imaging platform supports a dual wavelength infrared pulsed laser or two independent tunable infrared lasers for multichannel, multiphoton excitation imaging.

  • Optimally excite different fluorophores without having to repeatedly tune the laser
  • Independent power control of each laser line makes it easier to simultaneously capture fluorophores with differing efficiencies
  • Laser wavelengths beyond 1000 nm enables access to the growing library of red-shifted fluorescent dyes and proteins and practical third-harmonic generation imaging

Third harmonic generation imaging of porcine adipose tissue. Unlabeled porcine adipose tissue was irradiated with femtosecond laser at 1250 nm, second harmonic is detected from collagen fibers at 625 nm and third harmonic from lipid interfaces at 416 nm.

Create 3D Stimulation Reaction Maps

Specialized mapping scans utilize a pseudorandom sequence to deliver more precise spatial reaction maps when measuring electrophysiological response to optical stimulation. Direct electrical patch clamp recordings and fluorescence signals from calcium or voltage indicators can be overlaid on a high-resolution image. Intensity thresholds can be used to define a high-speed multipoint scan of the most active regions. This can be extended to 3D reaction maps with an optional piezo Z drive.

Combine a Wide Field of View with High Resolution

See your entire specimen at high resolution and in wider context with the multiarea time lapse (MATL) function:

  • Automatically capture and stitch multiple adjacent images over a very wide field of view using a motorized stage
  • Program time lapse acquisition over the entire composite field, or even non adjacent areas
  • Easily locate the position of specific cells in the larger image with the mapping feature

Expanded Analysis Functions

The FVMPE-RS imaging platform’s software is integrated with Olympus cellSens image analysis software, expanding the system’s analytical capabilities.

Optional features include:

  • 3D deconvolution for Z-stack images
  • Area estimation for each particle in an image
  • An image processing filter
  • Colocalization analysis

Separate Overlapping Channels with Spectral Deconvolution

Closely overlapping fluorescence spectra can complicate biological studies that look at multiple labels simultaneously. Now, overlapping spectral channels can be separated using spectral deconvolution based on a blind unmixing algorithm or previously saved multichannel profiles. Crosstalk between the channels can even be eliminated during image acquisition through live processing.

Normal Mode

Spectral overlap of red and green fluorescence causes cross-talk between the channels during normal acquisition.

Live Unmixing Mode

Live unmixing mode applies spectral deconvolution during image acquisition to better separate distinct fluorophores.
