Laser Head Focus Lense F120mm

A laser head focus lens F120mm with a focal length of 120mm (F120mm) is used to focus the laser beam to a fine point, suitable for various applications such as cutting, engraving, and marking. Here are key details about the Laser Head Focus Lense F120mm:

Key Features:

• Focal Length: 120mm, which determines the distance from the lens to the focal point where the laser beam is concentrated.
• Diameter: Common diameters for laser lenses are 20mm, 25mm, or 30mm, but the specific size should match your laser head.
• Material: Typically made from materials like ZnSe (Zinc Selenide) for CO2 lasers, or fused silica for fiber lasers.
• Coating: Anti-reflective coatings to maximize transmission and minimize losses. The coating type will depend on the wavelength of the laser being used.

Benefits of F120mm Focus Lens:

• Depth of Focus: A longer focal length provides a greater depth of focus, which can be beneficial for cutting thicker materials or maintaining focus over a longer distance.
• Spot Size: While the spot size may be slightly larger compared to lenses with shorter focal lengths, the F120mm lens balances spot size with depth of focus for versatile applications.
• Precision: Enables precise control over the laser beam, ensuring high-quality cuts, engravings, and markings.

Specifications:

• Focal Length: 120mm
• Diameter: Typically 20mm, 25mm, or as required by your laser head
• Material: ZnSe for CO2 lasers, fused silica for fiber lasers
• Coating: Anti-reflective coating specific to the laser wavelength

Maintenance and Care:

• Cleaning: Regularly clean the lens using appropriate cleaning solutions and lint-free wipes to remove dust and debris. Handle the lens with care to avoid scratches and fingerprints.
• Inspection: Periodically inspect the lens for signs of damage, such as scratches or coating degradation, which can affect performance.
• Replacement: Replace the lens if it shows signs of significant wear or damage to maintain optimal laser performance.

Installation:

• Alignment: Ensure the lens is properly aligned within the laser head to achieve the best focus and beam quality.
• Securing: Secure the lens firmly in place using the appropriate mounts or holders to prevent movement during operation.
