Why Choose 520nm Instead of 532nm?

Compared with traditional 532nm DPSS green lasers, a 520nm direct diode laser offers several advantages:

• Direct diode technology provides instant startup without warm-up time.
• More stable output across a wider range of operating temperatures.
• Improved reliability due to fewer optical components.
• Lower power consumption and greater energy efficiency.
• Rich emerald-green beam color with excellent visibility.

Note: A 532nm laser may appear slightly brighter to the human eye at the same output power because it is closer to the eye's peak sensitivity, while a 520nm laser offers superior stability and reliability.
