For sale is a Spectra-Physics / MKS Explorer One EONE-355-300 UV laser, manufactured August 2023.
The laser has been bench tested and is communicating correctly with the Spectra-Physics Explorer GUI.
Manufacturer: Spectra-Physics / MKS
Model: Explorer One EONE-355-300
Wavelength: 355 nm UV
Rated Output: 300 mW
Input Supply: 24 VDC / 75 W
Manufactured: August 2023
Serial Number: OV-7610-61
The unit has been fully powered and operationally tested prior to listing.
Testing included successful communication with the genuine Spectra-Physics Explorer GUI, laser emission, internal triggering at 50 kHz, temperature regulation and fan regulation.
External optical output has been independently measured at approximately 260 mW at 355 nm using a laser power meter.
Photographs include the laser operating and producing UV output onto a test card. The visible blue fluorescence shown in the photograph is produced when the 355 nm UV output strikes the material.
The internal laser monitor indicated approximately 245 mW during testing, compared with approximately 260 mW measured independently.
No attempt has been made to adjust the laser's factory calibration or service parameters in order to increase the measured output.

This is a 355 nm ultraviolet industrial laser intended for integration into suitable laser equipment.
355 nm radiation is largely invisible and presents a serious eye and skin hazard. It must only be installed and operated by suitably qualified personnel with appropriate enclosure, interlocks and laser safety measures.
