PolarPro QuartzLine ND100K (16 Stop) Filter 67mm – 99.9% Pure Fused Quartz for Maximum Clarity

The PolarPro QuartzLine ND100K (16 Stop) filter for 67mm threads offers precise neutral density control using 99.9% pure fused quartz. It targets filmmakers and photographers who need reliable exposure management in bright outdoor conditions and for long-exposure photography. The filter maintains true-to-life color accuracy while delivering the light reduction required for extended exposures and cinematic motion blur.

Why choose the QuartzLine ND100K?

The QuartzLine series emphasizes optical clarity and durability. Because PolarPro uses 99.9% pure fused quartz, you get consistent sharpness and minimal color shift. In addition, multi-coating reduces reflections, flares, and ghosting, so your images remain clean even in challenging lighting.

Key features and benefits

• Pure Fused Quartz Glass: Constructed from 99.9% pure fused quartz to provide exceptional clarity and accurate color rendition without unwanted color shifts.
• Multi-Coated for Maximum Clarity: Advanced multi-coating reduces reflections, flares, and ghosting for more consistent image quality in harsh lighting conditions.
• Neutral Density Control: ND strengths range from ND8 to ND100K, allowing precise exposure control whether you are balancing bright environments or creating long-exposure motion blur.
• Ultra-Durable Brass Frame: The filter frame uses aerospace-grade brass for durability and a secure fit, and it features a knurled design for easier attachment and removal.
• Scratch-Resistant Coating: A scratch-resistant coating helps protect the optical surface from everyday wear and tear, extending the filter’s usable life.
• Water and Oil Repellent: Hydrophobic and oleophobic coatings make the filter easier to clean and more resistant to water, oil, and fingerprints—useful when shooting in rugged environments.
• Protective Case Included: The filter ships with a custom protective case to keep it safe during transport and storage.

Designed uses and applications

Use this ND100K filter when you need substantial light reduction for creative or technical reasons. For example, filmmakers can achieve cinematic motion blur in bright light, and landscape photographers can lengthen exposures for smooth water and cloud movement. Moreover, the filter suits both outdoor shoots and demanding fieldwork where durability matters.
