Absolutely. At Felix Glass, we specialize in custom optical glass domes tailored to your exact project requirements, from initial design to final delivery.
**Custom Size & Geometry:**
We manufacture domes in a wide range of sizes, from small miniature domes for compact sensors to large-diameter domes for industrial and aerospace applications. We can produce domes with custom:
- Outer and inner diameters
- Wall thicknesses (including uniform or tapered profiles)
- Radii of curvature (both spherical and aspherical options)
- Edge profiles (bevelled, flat, or threaded mounting surfaces)
We can work directly from your CAD drawings or specifications, and our engineering team can also help refine your design for manufacturability and optimal optical performance.
**Advanced Coating Options:**
To maximize the performance of your custom optical glass dome, we offer a comprehensive range of thin-film coatings:
- **Anti-Reflective (AR) Coatings:** Our multi-layer AR coatings significantly reduce surface reflection, boosting light transmission to over 99.5% across your target wavelength range (visible, NIR, SWIR). This eliminates glare, improves image clarity, and enhances the performance of your optical system.
- **Infrared (IR) Coatings:** For night vision, thermal imaging, and IR sensor applications, we offer high-transmission IR coatings optimized for specific wavelength bands.
- **Diamond-Like Carbon (DLC) Coatings:** These ultra-hard coatings provide excellent scratch and chemical resistance, ideal for domes used in harsh, high-abrasion environments.
- **Anti-Fog & Hydrophobic Coatings:** These coatings repel water, prevent fogging, and make the dome surface easier to clean, perfect for outdoor surveillance and underwater applications.
- **Custom Filter Coatings:** We can also apply custom bandpass, notch, or neutral density filters integrated directly onto the dome surface for specialized optical systems.
Whether you need a one-off prototype or a high-volume production run, we ensure every custom optical glass dome meets our strict quality standards and your precise specifications.
