Laser Spare Parts: Optical ZnSe Laser Lens 50.8mm 20 mm Diameter

Product Description

Features:
Diameter: 0.79" (20mm)
Focal Length: 1.5" (38.1mm) / 2" (50.8mm) / 2.5" (63.5mm) / 3" (76.2mm) / 4" (101.6mm)
Material: ZnSe
This would be a great lens for a co2 engraver or laser cutter, to focus the beam into a tight spot.
We adopt the material ZnSe to produce which is same to the top player of the industry, American II - VI.

Specs:

Details:Advantages
• Adopted ZnSe material imported from USA which can go with high power density;Deliang system, and increased the light transmittance of the parts;
• The transmittance of working waveband in co2 laser industry reaches 99.8%;
• The lens consist in many advantages such as precise focus, thin-film coating anti wiping, higher luminous flux, etc. For which materially improves your work efficiency.

Benefits
• Stable focus spot, better effect in cutting and engraving, bearable for high power density, and strong thin - film coating against peeling off and durable for wiping;
• Double-side coated anti-reflection coating, the light transmission of the parts increased by cylindrical surface polishing, reduction or elimination on stray light of the optical system;
• The stability of focus position strengthened, the cutting & engraving speed of some applications improved, and the ability for reflected light enhanced;
• More bearable for wiping, longer life span as well as better process to radioactive coating.

Similarity nearly 99%;While its price is 50% less than that of American II-VI..The excellent lens material directly results the stability of laser system. The lens we produce is not a fake, it consists in many advantages such as precise focus, thin-film coating anti wiping, higher luminous flux, etc. for which materially improves your work efficiency.

Product Uses

Tips: The imported ZnSe material are available from Russia, German, France, USA, etc. among which the one from USA appears best in quality and, generally, the brand II-VI represents on market. All the material we use is ZnSe imported from USA and it will materially increase working efficiency.The harm of poor quality lens: rough focus which makes the user unable to cut product efficiently during working such as failures of cutting through or off, slow cutting, etc. which influence work efficiency as well as short life span, easy crack and film peeled off.
