The Polaris Series extends Eolite's portfolio of FPD repair lasers with a targeted OEM product specifically designed to meet the needs for emerging LCD manufacturing technologies. The Polaris 300 also enables applications for medical device manufacturing, laser ablation, laser annealing and high energy spectroscopy.

Polaris 300

The Polaris 300 is an air-cooled 100Hz diode-pumped Nd:YAG laser with four-wavelength output capability.

Industrial Q-Switched DPSS Laser

The Polaris-300 facilitates fast throughput with selectable repetition rates from single shot to 100-Hz continuous. The diode-pumped laser architecture allows for superior shot-to-shot stability and beam uniformity for repair of micron-level feature sizes.

The flat-top beam profile enables maximum beam utilization and uniform cutting and welding.

Multiple user-selectable wavelengths (1064, 532, 355 and 266 nm) and motorized optical attenuators provide the ability to cut a variety of materials and selectively remove certain materials while leaving others unaffected.

The diode-pumped laser does not have any consumables and is designed to run in a 24x7 continuous operation.

The air-cooled laser head further simplifies system design without the need for cooling water.

The Polaris-300 requires no water cooling and comes integrated with a cleanroom compatible fan. It offers industry-leading energy stability and beam uniformity with its proprietary diode-pumped laser architecture. The laser can be configured in multiple wavelengths for optimal flexibility.
