Optics Polishing Pads
Spartan Felt's optics and electro-optics polishing pads are built for applications where surface sensitivity and consistent, low-to-medium pressure finishing matter most — from glass types to silicon carbide and sapphire optics to delicate, fragile components polished on hand-held equipment. Use the comparison below to find the right pad for your material and process, or contact our team for a custom recommendation.
| Pad | Best For | Hardness | Compression | Key Trait |
|---|---|---|---|---|
| Series 5200 | Silicon carbide | C Scale 60 ± 5 | 4% | Fibrous non-woven construction with excellent surface wear characteristics |
| HPB-101CC | Glass, sapphire, silicon, silicon carbide, ceramics, optics, plastics, some metals | C Scale 40 ± 5 | 2–4% | Widest material compatibility of the group |
| EL1-KS | Semiconductor, compound semi, optic/electro-optic & sapphire applications | C Scale 58 | 2% | Premium stock-removal pad built for durability |
| Spartan Warrior Pad | Most polishing applications, general-purpose | C Scale 42 | 5% | Versatile pad tunable across processes by adjusting process variables |
| Spartan Durotex | Optics, electro-optics, semiconductor, aluminum discs, LCD/plasma display, ceramics | N/A | N/A | Polyurethane for single-step polishing across a wide variety of materials |
| HPB6040 | Hand-held machines, fragile and delicate items | Shore C 40 | 4–6% | Built for low-to-medium pressure, hand-held polishing applications |
How to decide:
- Polishing silicon carbide optics? Series 5200 is purpose-built for this material, with a fibrous non-woven construction for consistent surface wear.
- Working with sapphire or compound semiconductor optics? EL1-KS is engineered specifically for semiconductor, compound semi, and optic/electro-optic & sapphire applications, with low compression (2%) for tight process control.
- Handling fragile or delicate optical components on hand-held equipment? HPB6040 is built for low-to-medium pressure applications where surface sensitivity matters most.
- Need a general-purpose pad that can be tuned across multiple processes? The Spartan Warrior Pad adjusts to most polishing applications by varying process parameters.
- Polishing in a single step across optics, electro-optics, and other materials without multiple stages? Spartan Durotex is designed for that workflow.
- Need the widest material compatibility? HPB-101CC spans glass, sapphire, silicon, silicon carbide, ceramics, optics, plastics, and some metals in one pad.
