PTFE integrating sphere insert - good optical properties for use with reflectance integrating spheres/transmittance integrating spheres/photometric integrating spheres/integrating sphere light sources

ColorSpace Co.Ltd offers PTFE integrating sphere liners with high reflectivity, spectral neutrality, and excellent optical properties. The versatile and customizable design adapts to various instrument optical path configurations, making them widely used in optical instruments.

Unlike integrating spheres coated with sprayed PTFE, our foamed PTFE integrating spheres are manufactured through a specialized process: PTFE powder is modified, foamed, molded into a spherical shell, and then polished to achieve a smooth finish. Key advantages include:

• Thick, durable coating that resists peeling
• Superior optical performance: High reflectivity, spectral neutrality, and stability
• Lightproof with high coating strength and integrity, resistant to moisture—suitable for underwater measurements and even harsh environments (e.g., acidic, alkaline, or saline solutions for optical testing)
• Customizable spherical shapes to fit diverse optical instrument designs

These properties make our PTFE integrating spheres ideal for demanding applications across optical instrumentation.
