New Wave Research introduces its 2nd generation excimer laser ablation system with full beam homogenization. Craters in quartz having <10nm flatness have been demonstrated making the UP193HE (Homogenized Excimer) the preferred choice for diamonds, inclusions and other highly transparent materials. Features - <10nm flatness in quartz achieved.
- Highest energy density available - to 35J/cm2
- 2% stability
- Broadest spot size range - 4 to 270 µm
- Closed-loop control via ICP-MS, IRMS
- Sample Map Navigation for up to 50mm virtual FOV (field of view) of samples
- Motorized zoom magnification to 1200X
- Real-time measurement of energy & energy density
- Pulse rates from 1 to 50Hz - continuous pulsing, single shot and burst modes.
Applications - Gemstones, diamonds
- Geochemical analysis of fluid inclusions, zircons, calcite, apatite, basalt
- Forensic analysis of plastics, glass, ceramics
- Laser fluorination (e.g., 18O/16O, 17O/16O, 34S/32S, 33S/32S)
- Rare gas isotope ratio measurements (e.g., 40Ar/39Ar dating)
