7800 LASOS Argon Laser Replacement Photograph

7800 LASOS Argon Laser Refurbishment

 

Design

Matching the original specifications, National Laser replacement tubes are fit, form, and function compatible with the original design of the 7800 laser. National Laser's replacement tube designs often result in improved performance and increased lifetimes over competitor's products.

When refurbishing an argon laser head with a new tube, the primary component of the laser is entirely replaced. In addition to replacing the laser tube with new material, National Laser inspects, and if necessary, replaces damaged components in the laser head in order to offer a new laser warranty.

LASOS Company Background

The LASOS argon laser is the “workhorse“ in many applications in biophotonics especially when used for fluorescence excitation. Its ability to emit several wavelengths simultaneously results in an unbeatable price-performance ratio. LASOS argon lasers cover a broad spectrum with emission in the blue and green spectral range, with wavelengths in the range of 454 nm to 514 nm, in single-wavelength and multi-wavelength versions. All laser tubes have an internal mirror vacuum-tight hardsealed and integrated resonator construction optimizing life time and power stability.

The LASOS argon laser modules are compact, economical and available with several cooling options. The lasers are designed for multipurpose solutions in scientific and OEM applications such as confocal laser scanning microscopy, DNA sequency, flow cytometry, analytical chemistry, fast-flow-rate particle measurements, digital imaging, medicine, basic research or entertainment.
