Micro Laser Systems (µLS) has introduced a high stability green diode laser with diffraction limited performance for more demanding applications. These include: confocal microscopy, flow cytometry, fluorescence excitation, particle analysis, direct laser writing and metrology.
This new laser in the Lepton IV OEM series delivers a circular Gaussian beam with high output stability, has a low power requirement, and is built into a smaller package size when compared to typical Argon and diode pumped lasers. Output power is up to 40 mW and can be continuous wave, pulsed, or modulated, while the low wavefront error allows for the generation of micron and sub-micron spots sizes, or the production of a large clean beam for illumination.
The OEM units are available with or without temperature control – depending on your application – and are provided with numerous threaded mounting holes for secure installation.
Ultra-high resolution Raman microspectroscopy is now available throughout the UK and Ireland as Elliot Scientific introduces the CRAIC Artemis™ Raman Spectrometer – available as an add-on for modern research grade microscopes, or as an option for CRAIC’s existing range of UV-Vis-NIR Microspectrophotometers.
Perfect for research, metrology and quality control, the CRAIC Artemis™ Raman system has been designed specifically for microscopic sample. Its patented virtual slit technology dramatically increases the sensitivity of the spectrometer, offers an extraordinarily large spectral range, yet maintains the high speeds and spectral resolution for which CRAIC microspectrometers are known.
The Artemis™ modules are available in many different laser wavelengths and two can be combined for the ultimate in experimental flexibility. Easy to use and economical to own and operate, they enable rapid sample analysis within life sciences, materials science, chemistry and physics.
Each module includes a choice of diode laser, imaging and microscope optical interface, durable solid-state Raman spectrometer, and software from CRAIC – the experts in microspectroscopy.
