Toggel FLIM Camera

The LIFA Toggel is a next-generation camera-based fluorescence lifetime imaging (FLIM)  system that makes functional imaging easier by combining excellent light sensitivity with fast image acquisition and data analysis using LIFA software. It minimizes the duration of lifetime measurements and is compatible with any wide-field microscope. In addition to its broad range of applicability and advanced technology, Toggel is easy to install and maintain.

The Toggel camera features a unique image sensor designed and optimized especially for fluorescence lifetime imaging applications. This image sensor enables lifetime imaging at unprecedented frame rates with the single-image fluorescence lifetime imaging microscopy (siFLIM) method [2]. The camera records two images during a single exposure that are shifted 180° in phase with respect to each other. Demodulation of fluorescence light and the phase shift introduce a difference in light intensity between two images which can be used to track the changes in the fluorescence lifetime. As a result of recording images simultaneously, the artifacts due to cellular movement are eliminated and photon efficiency of the image acquisition is significantly improved.

The built-in time-lapse feature is a useful tool for tracking the changes in the fluorescence lifetime, which is widely used in live-cell imaging. The feature is very easy to use and it only requires the user to set the duration and time between measurements and the software generates the time-lapse video.

This camera also provides high throughput screening capability, with automated lifetime-based screening and characterization of fluorescent proteins.

LIFA Toggel FLIM Microscope System

LIFA System

The Lambert Instruments FLIM Attachment is the fastest and easiest way to do Fluorescence Lifetime Imaging Microscopy (FLIM) and Forster Resonance Energy Transfer (FRET) measurements. With the Lambert Instruments FLIM Attachment (LIFA), you record quantitative lifetime data in a matter of seconds. It’s easy to connect the Toggel FLIM camera and light source to your microscope. And our specialized software records the images, analyzes the data instantly and presents the results visually for easy interpretation.

From recording images to lifetime calculation and data analysis. Our advanced software instantly analyzes your data and presents the calculated fluorescence lifetimes visually.

  • It’s fast: Record fluorescence lifetime imaging microscopy (FLIM) data in a matter of seconds. Compared to alternative methods like time-correlated single photon counting (TCSPC), the LIFA is over 100 times faster.
  • It’s easy: Our advanced software instantly analyzes your data and presents the calculated fluorescence lifetimes visually. Recorded images are compatible with ImageJ, FIJI, Matlab and MetaMorph. Detailed statistical data can be exported to Excel worksheets.
  • It’s compatible: The LIFA is compatible with every fluorescence microscope with a camera output. This includes fluorescence microscopes by Leica, Nikon, Olympus, TILL and Zeiss, as well as spinning-disk confocal and TIRF configurations.
