Original Focusing Lens D20T4.5 Series
Optimize your handheld laser system with high-precision original D20T4.5 focusing lens optics. Designed specifically for SUP23T and SUP23S process heads, these lenses are crafted from high-purity fused silica glass featuring double-sided AR coatings. They deliver low optical absorption, superior thermal stability, and maximum energy efficiency for both specialized laser welding and surface cleaning applications.

Handling & Maintenance Guidelines
Precautions for Installation
- Wear clean powder-free gloves or rubber finger cots during handling to prevent skin oil and dirt contamination.
- Avoid using metal tools such as tweezers to handle optical components, as they can chip glass edges.
- Do not place lenses directly on plain paper tissues or rough surfaces without clean optical tissue padding.
- Handle precision infrared optical components with extra care; anti-reflective coatings are prone to scratches.
Taboos for Lens Maintenance
- Never touch the polished optical mirror surface directly with unwashed bare fingers.
- Do not exhale directly onto the lens surface or use unfiltered, oily shop air lines to blow dust off.
- Prevent optical glass surfaces from coming into direct contact with hard or abrasive tools.
- Refrain from using coarse wipes, standard paper towels, or applying excessive force when cleaning.
Lens Assembly Guidelines
Important Note: Model D20T4.5F150 is dedicated for laser welding, while models F200, F400, F600, and F800 are engineered specifically for laser cleaning mode. Please ensure correct model selection prior to ordering.
Frequently Asked Questions
What is the key difference between F400 and F800 cleaning lenses?
The D20T4.5F400 has a shorter focal length with minimal laser power loss, providing higher laser energy density for removing stubborn rust, thick paint, and heavy oxides. The D20T4.5F800 features a longer focal length, allowing a broader laser scan path, but its focused energy density is lower than that of the F400.
Can I use the cleaning focusing lenses (F200, F400, F600, F800) for laser welding or cutting?
No. Models F200, F400, F600, and F800 are engineered strictly for the laser cleaning function on SUP23T/SUP23S heads. They cannot be used for laser welding or cutting operations, as welding requires a much tighter focal spot (such as provided by model D20T4.5F150).
How should I safely clean and maintain this optical focusing lens?
First, blow off loose dust particles using a dry optical hand blower. Then, lightly dampen a lint-free optical swab with high-purity anhydrous isopropyl alcohol and gently wipe across the lens surface in one continuous direction without applying heavy pressure.
