The High-Stakes Balancing Act in Optical Cleaning
For engineers working on optical assemblies, cleaning is one of the most critical yet risky steps in ensuring final performance. The challenge lies in a paradox: cleaning must remove every contaminant without introducing new scratches, fibers, or particles. Too often, the very act of wiping is the source of defects that compromise alignment, clarity, and overall functionality.
The Conventional Trade-Off: Scratch vs. Shedding
Until recently, optical engineers had to choose between two imperfect tools:
- Non-Sealed Edge Wipers – While soft and flexible, these wipers are cut from fabric rolls, leaving exposed, frayed edges. During use, they release fibers that redeposit onto the optical surface, undermining cleanliness.
- Sealed-Edge Wipers – Sealing is intended to prevent fiber release, but conventional seals are thick and rigid. These hardened edges can act like a blade, creating microscopic scratches that permanently degrade optical performance.
This trade-off—fiber shedding vs. scratching—has defined optical cleaning for decades.
The Foamtec Breakthrough: Thin-Sealed Edge Technology
Foamtec has engineered a new solution that resolves the cleaning dilemma: thin-sealed edge technology. Unlike conventional seals, this micro-thin edge eliminates fiber shedding without creating a rigid, abrasive line that can scratch sensitive surfaces.
HT5790
- HT5790 (9×9″) – Designed for wide cleaning paths on larger assemblies, ensuring efficient coverage with no risk of scratching.
- HT5740 (4×4″) – Ideal for precision cleaning of smaller mirrors, lenses, and optical elements where space is limited and delicacy is paramount.
By combining superior cleanliness with scratch-free safety, Foamtec’s thin-sealed edge wipers set a new standard for optical assembly cleaning—removing particles and residues without compromise.
