Zeiss Lasos LGK-7812 ML4 Laser Module with Control Box

The Lasos LGK 7812 ML4 is a high-performance argon ion gas laser engineered for demanding scientific and industrial applications requiring stable, multi-wavelength blue-green laser emission. Operating across a typical spectrum of 450–530 nm, it delivers prominent laser lines at 488 nm and 514.5 nm, among others, with a maximum output power of up to 500 mW.
Designed for precision, the LGK 7812 ML4 features an excellent beam quality (M² < 1.2), vertical polarization (> 500:1), and output power stability within ±1% after warm-up. The laser’s compact air-cooled design ensures efficient thermal management and continuous operation with minimal maintenance.

Ideal for laser microscopy, flow cytometry, holography, and other high-resolution optical applications, this multi-line argon laser offers a superior combination of optical clarity, reliability, and spectral purity.

Key Features:
• Multi-line output: 454.5 nm, 457.9 nm, 476.5 nm, 488.0 nm, 496.5 nm, 501.7 nm, 514.5 nm
• High beam stability and low noise (<1% RMS)
• Compact, air-cooled housing for easy integration
• Requires dedicated Lasos LGN 7812 power supply
