The Coherent OBIS XT family delivers UV wavelengths of 360 nm, 349 nm, 320 nm, and now into the red spectrum at 640 nm. The Coherent OBIS 640 XT is an innovation in the expanding life science market, specifically addressing the growing demand for a 640 nm laser capable of exciting fluorescent dyes in super-resolution microscopy (SRM) and many other applications.

The leap in optical resolution, achieved through its higher output power compared to other OBIS LS/LX models, enables the observation of single molecules and intricate cellular features. This advancement is crucial for SRM as it overcomes the limits of standard optical resolution in microscopes.

The brand-new Coherent OBIS 640 XT, the latest addition to the Coherent OBIS XT family, combines the compactness and power of Diode-Pumped Solid-State (DPSS) technology with the Coherent Sapphire and Coherent OBIS LS/LX smart laser platforms. With its integrated controller, the OBIS 640 XT stands out for its low-noise output and impeccable beam quality – ensuring reliability for life science applications.

The OBIS LX products at 637 nm, 647 nm, and 640 nm are based on available laser diodes and output power levels. The OBIS 640 XT offers up to 1000 mW in a compact package with minimal heat dissipation, making this expansion an innovative catalyzer for applications such as super-resolution microscopy, DNA sequencing, flow cytometry, particle measurements, and high-throughput screening.
