Meet us at ELMI 2026

16-19 June 2026 – Coimbra, Portugal

Enabling Next-Level Fluorescence Applications

Join TOPTICA Photonics at ELMI 2026, taking place June 16–19, 2026, in Coimbra, Portugal.

As one of the leading events for the Light microscopy and Bioimaging community, ELMI brings together researchers, imaging experts, technology developers, and industry partners from across Europe and beyond.

Meet TOPTICA and our booth partners RAPP and Chroma to learn more about advanced technologies for cutting-edge microscopy and fluorescence imaging applications. Exchange ideas with our experts and discuss how our combined solutions support demanding imaging workflows with reliable performance, seamless integration, and high-quality optical components.

Laser live in action!

See our lasers live in action at a fully operational 2p and confocal microscope.
We will show the fiber coupled FemtoFiber ultra 920 for GFP and GCaMP excitation.
The confocal setup will be powered by an iChrome CLE with 50 mW ex fiber!
More information can be found here: ELMI2026

Joint Workshop with Thorlabs

Together with Thorlabs, TOPTICA will host a dedicated workshop covering the latest developments in microscopy and imaging technologies.

Join a live demo with the fiber coupled TOPTICA FemtoFiber Ultra 920 for GFP and GCaMP two-photon excitation at the ultra-compact Thorlabs Prelude 2p-microscope.

The TOPTICA iChrome CLE gives light to Thorlabs Veneto confocal microscope. The iChrome CLE features four wavelengths: 405 nm, 488 nm, 561 nm and 640 nm out of a polarization maintaining single-mode fiber. The power levels are guaranteed ex fiber!

Join our Company Workshops on Wednesday and Thursday 💡

FemtoFiber ultra FD with fiber delivery

FemtoFiber ultra FD – A game-changer for simplifying multi-photon microscopy

Completely replacing the free-space paths between a Watt-level femtosecond laser and a two-photon microscope is a game-changer for modern microscopy. Delivering femtosecond pulses directly from the laser source to the microscope via an optical fiber enables completely new microscope designs and brings laser safety and ease of use to a new level.

Compact & Low cost of ownership
Clean Pulse Technology
No mirror alignment

Lasers in 2P-Microscopy

Illuminating Life in Depth – Two-Photon Microscopy

The ability to visualize structures hundreds of micrometers deep in living samples has made two-photon microscopy indispensable for studying how cells, tissues, and networks behave in their natural context.

To drive the nonlinear two-photon excitation process efficiently, the laser must deliver:

High peak power (requiring typically femtosecond pulses).
Diffraction-limited beam quality.
Wavelength matching to the fluorophore’s absorption.
A repetition rate matched to the fluorescent lifetime of the dye (typically 20-80 MHz)

Femtosecond fiber lasers have become the preferred light source for TPEF due to their stability, compactness, and hands-free operation — outperforming traditional Ti:Sapphire lasers in reliability and maintenance effort.
