- All laser sources are mounted in one single enclosure. Thus requiring less floor space.

Different polarization angles optionally available. - All laser sources are mounted in one single enclosure. Thus requiring less floor space. However, for larger quantities, they can also be supplied in a customized enclosure that fits better into or onto the OEM-machine. - Several interface possibilities available inside the laser source, allowing customized interfacing possibilities to any CNC-control or machine. - All lasers are standard available with a high-quality laserdiode pointer for easy alignment of external beam transport, as well as simple positioning on the work table with closed shutter. This allows to show where the impact of the CO 2 laser beam will be, in turn increasing security. - Maximum power is always at least 10 % higher than the specified rated output power, which allows reliable cutting parameters without any risk of the laser source being overloaded. The above also contributes to a very long meantime between maintenances (6.000 to hours). - All laser models are equipped with a dynamic power control, ranging from zero to rated output power. Therefore, the lasers are performing as efficiently commanding high power or low-power. - Automatic vacuum leak check function.

3 Page 3 of 7 SPECIFIC CHARACTERISTICS - Standard gas low pre-warning : when a laser gas cylinder is almost empty (pressure drop), a warning signal is given (may also be given through the interface on the CNC screen) without the laser source being turned off. In this way, empty gas cylinders can be replaced during production, without having to switch off the laser.!! No more production loss when replacing an empty gas cylinder!! - Patented manual gas override function. The laser gas consumption can be adapted manually (by the end user in production), so that the laser even can operate with contaminated gases or with a vacuum leak. - All PRC lasers are standard equipped to operate on three separate gases or on premix gas. Every laser has its own internal gas mix unit. - Furthermore, the gases do not have to be of the highest purity. See PRC gas specifications, which of course means major savings for the end user. - All laser source models are equipped with an Oil-free and maintenancefree Turbo Flow II Compressor (patented by PRC), eliminating any contamination of the laser gas circuit and in turn resulting in no contamination of the internal laser optics or plasma tubes. This reduces the maintenance cost to a minimum and the optics life is considerably increased ( to hours).

4 Page 4 of 7 SPECIFIC CHARACTERISTICS (Continued) - PRC LIGHTVAR RESONATOR on all models with only 4 internal optics!! The PRC Lightvar resonator, which does not require any watercooling results in a very high thermal stability. Tests carried out at the EHT University in Zürich did not show any measurable expansion in case of temperature rise of more than 40 C. Since the resonator is not water-cooled, the stability is entirely independent of the water cooling temperature, as well as of the purity of the water cooling circuit. Also the mode, power and pointing stability are entirely independent of the water temperature. Therefore, there is no need for a special chiller cooling unit with very tight temperature tolerances. In the resonator part, the water cooling only serves to take away the heat from the mirrors. A temperature control of 2 C is sufficient here!! - The temperature-independent resonator structure allows mounting or replacing of resonator mirrors without any need for resonator retuning or realignment!! - All laser models can be delivered with customer-specified beam diameters, to achieve the best processing results with particular focus lenghts. - Most laser models can be delivered with different mode structures. The mode structure can even be modified afterwards in the field!! - PRC lasers can be delivered in a standard enclosure or in a customized enclosure (for larger quantities) which can be designed in cooperation with the OEM. - Furthermore: PRC is the only supplier world-wide offering dual beam lasers.

WARRANTY All laser models are covered by a warranty without limitation of running hours (see PRC warranty terms).

6 Page 6 of 7 THE EXTREMELY EASY MAINTENANCE CONTRIBUTES TO AN ENHANCED RELIABILITY & CONSIDERABLE REDUCTION OF MAINTENANCE COST - Only the vacuum pump oil and filter, and water filter, have to be replaced over a period of hours. No other service is required, within this period of time. - Only at hours, a small preventive maintenance has to be performed (+/-1 day of work). - Only every hours a standard maintenance will be done ( 1~2 days of work) - Very long life of internal laser optics : to hours. - The PRC laser enclosures are designed to allow easy access to and allow easy replacement of the parts, thus reducing the possible downtime to a minimum. - All PRC lasers have an entirely modular structure, which further contributes to easy maintenance. - The internal laser optics ( only 4 pieces) can be cleaned or replaced mostly without any need for laser retuning!! So less downtime. - No expensive special beam shaping optics => less maintenance cost! - No need to return the laser ever to the manufacturer for repairment, everything can be done on-site, in the field. PRC SERVICE SUPPORT - Worldwide service network. - Full technical support by trained personnel. - Laser applications know-how and support for OEM-customers and endusers. - Interventions in most countries within 24~48 hours.
