The gem family offers key microscopy wavelengths including 473, 532, 561 and now 640 nm, amongst others. With all wavelengths available at […]
Localization Microscopy
Read the recently published microscopy article published in Wiley Online, PhotonicsViews. The article focuses on localization microscopy, and how high–power continuous wave lasers can be used in super-resolution microscopy. Super-resolution microscopy overcomes the Abbe diffraction barrier allowing resolution greater than 200-300 nm. The article details the principles of single-molecule localization microscopy (SMLM), and how it enables improved resolution by […]
Watch our Two-Photon Microscopy animation now
Achieving high resolution and increasing imaging speeds are two critical factors for effective two-photon microscopy. Our newest animation demonstrates how our helixx, with a repetition rate of 250 MHz, is tailored to the decay times of typical fluorophores to reduce photobleaching and toxicity and increase imaging speed and cell view times. Its short pulse duration […]
venteon – few cycle, ultrashort pulse
The venteon ultrafast laser range is based around short pulse generation and designed to meet individual needs. Working directly with your engineers, our venteon lasers are optimised for power, bandwidth and CEP stabilisation. The venteon can be used to meet a range of applications from few-cycle pulse generation and attosecond science to two-photon microscopy, all […]
Enhancing two photon microscopy
Two-photon microscopy has many advantages over conventional microscopy including; minimal photo-bleaching effect and sample damage, higher imaging depth of live cells, higher excitation efficiency, and simultaneous excitation of multiple fluorophores with the promotion of autofluorescence. Ultrashort (<10 fs) pluses enhance the two-photon microscopy technique. The peak power for a given average output is much higher […]
4 Tips to Achieve High-Quality Imaging in Microscopy Applications
Microscopy is an important technique across many disciplines both in research and commercially. There are many techniques used in microscopy including, spanning confocal, lattice light sheet and multiphoton—and for all, image resolution is a key factor. Resolution plays a big role in microscopy’s success as it refers to the microscope’s ability to select detail in […]
Terahertz Cyclotron Resonance Spectrometer
Dr. Darren Graham tells us about the development of the terahertz cyclotron resonance spectrometer at the Photon Science Institute, University of Manchester. Cyclotron resonance has been about since the 1960’s and the technique has led to the development of new semiconductor materials, producing light-emitting diodes and transistors. In order to perform the techniques, you need […]
A technique to achieve high resolution and faster sampling in Microscopy
Fluorescence microscopy is a continually developing tool for imaging biological samples, however, the same challenges are faced throughout the microscopy world: High-resolution levels Faster sampling rates Light-sheet microscopy is a technique that employs scanning a sample as a plane of laser light, a second excitation lens is placed on a perpendicular axis to the detection […]
Latest PLIM research released
In a recent scientific paper published in the Journal of Innovative Optical Health Sciences by The Core Imaging Facility at the University of Ulm, the use of fast repetition rate fs pulsed lasers is investigated to advance PLIM (phosphorescence lifetime imaging) microscopy. PLIM is traditionally carried out with 80 MHz Ti:Sapphire lasers, however this paper […]
Ultra-low noise
Visit the axiom 532 web page to view the detailed specifications of the newest ultra-low noise laser from Laser Quantum. The axiom 532 lends itself to Ti:Sapphire pumping as the pump laser noise is transferred directly to the noise of the Ti:Sapphire laser. When the typical noise value is <0.02% RMS, this factor is greatly […]
