Laser Focusing Lens D28 F125mm Raytools BM109 with Holder 0-3kw
The Laser Focusing Lens D28 F125 with holder is engineered specifically for Raytools BM109 fiber laser heads operating up to 3kW. This high-precision optical assembly ensures exceptional beam concentration, minimal thermal distortion, and a prolonged service life.
Performance Overview of the Laser Focusing Lens D28 F125
In advanced industrial fiber laser processing systems, the ultimate cutting and welding precision is dictated by beam concentration. The Laser Focusing Lens D28 F125 with holder performs the vital task of focusing the parallel laser beam into a high-density energy spot. With its 125mm focal length, this optical system provides the perfect balance between depth of focus and spot size, making it a highly popular configuration for cutting medium-thickness metals. This optical profile is ideal for fabricators who regularly process carbon steel, stainless steel, and aluminum alloys within a high-speed production line.
Choosing a premium Laser Focusing Lens D28 F125 is essential for maintaining process stability. Manufactured by Jinan Allwin CNC Machinery Co., Ltd. under the brand FWINCNC, this pre-assembled unit is optimized for 0-3kW power levels. By delivering a pre-mounted assembly, it completely avoids dust contamination during lens replacement and guarantees optimum coaxial alignment, which translates directly to superior edge quality.
Technical Excellence of the Laser Focusing Lens D28 F125
To survive the intense thermal load of industrial laser operations, every single optic must be manufactured to the highest standards. This particular Laser Focusing Lens D28 F125 is constructed using high-purity synthetic fused silica. This material features an exceptionally low thermal expansion coefficient and a massive damage threshold. As a result, the optical system can easily withstand continuous 3kW laser loads with negligible thermal focus shift, ensuring consistent performance throughout long manufacturing shifts.
Furthermore, the optics feature double-sided anti-reflective (AR) coating designed to operate efficiently in the 1030-1090nm fiber laser band. With a transmission rate exceeding 99.9%, this specialized coating drastically reduces energy loss, thermal buildup, and back-reflection, which significantly extends the overall lifetime of the lens. The dual-sided coating processes maximum transmissive energy while protecting the delicate optical substrates from back-reflections during copper and brass processing.
Structural Mechanics and Precision Holder
The pre-assembled holder is CNC precision-machined from anodized aluminum. It is engineered to fit seamlessly inside the Raytools BM109 focusing chamber. This precise metal-to-metal contact prevents alignment errors during installation and ensures that the laser beam remains perfectly aligned with the nozzle. The anodized aluminum housing undergoes a hard-wear oxidation treatment, allowing the cartridge to withstand mechanical abrasion from repetitive replacements without shedding metallic micro-particles. By replacing the entire cartridge with a pre-mounted Laser Focusing Lens D28 F125, operators can drastically reduce machine downtime and eliminate the risk of introducing dust into the sensitive optical housing.
Optical Compatibility and Diverse Applications
This 28mm diameter and 125mm focal length specification is a highly versatile industry standard. While it is primarily compatible with the Raytools BM109 series of autofocus and manual focus heads, its adaptable design makes it suitable for many other medium-power laser setups. We ensure that our Laser Focusing Lens D28 F125 meets or exceeds original equipment manufacturer standards, making it highly reliable for flatbed sheet metal cutters, 3D robotic cutting systems, and high-precision handheld laser welding systems that require a 28mm diameter focus cartridge.
Maintenance Guidelines and Lifespan Optimization
Optical components are highly sensitive to external contaminants. When replacing your Laser Focusing Lens D28 F125, always work in a clean, dust-controlled environment. Ensure you are wearing protective finger cots or lint-free gloves before handling any components. Gently clean the optical glass using high-purity isopropyl alcohol and dedicated optical wipes, applying a gentle, single-direction swipe. Never apply physical force. Additionally, we recommend checking the sealing rings within the focusing chamber regularly to prevent process gases from leaking into the optics chamber, keeping your FWINCNC consumables in pristine condition.
