PolarPro QuartzLine Circular Polarizer (CPL) Filters. These filters are designed for photographers and videographers who want exceptional optical quality and durability. Here's what you need to know:

1. Construction and Materials:

   • The QuartzLine filters are constructed using Cinema Series™ Glass, which is made in Germany. This glass ensures both durability and outstanding optical clarity.
   • The single-lens element design produces a very low refractive index of just 1.46, minimizing any unwanted optical effects.
   • The filter frame is made from an over-engineered aluminum alloy, ensuring robustness and longevity.

2. Purpose of a Circular Polarizer (CPL) Filter:

   • A CPL filter is primarily used to control reflections and glare in your images.
   • It selectively reduces reflections from non-metallic surfaces such as water, glass, and foliage.
   • By rotating the filter, you can adjust the level of polarization to achieve the desired effect.

3. Optical Properties:

   • The QuartzLine CPL filter has a 2.5x filter factor, which translates to approximately 1.3 stops of light reduction.
   • It enhances color saturation and contrast, making your images pop.
   • Additionally, it helps reduce atmospheric haze, especially in landscape photography.

4. Coatings and Resistance:

   • The filter is multicoated to minimize reflections, ghosting, and lens flare.
   • It is also resistant to water, oil, and scratches, which is crucial for outdoor use.
   • The brass filter ring ensures smooth threading onto your lens.

5. Sizing Options:

   • The QuartzLine CPL filters come in various sizes to fit different lenses. For instance:
     • The 95mm version is suitable for large-diameter lenses commonly used in professional photography.
     • The 82mm version is also popular and fits many standard lenses.

6. Use Cases:

   • Landscape Photography: Enhance skies, reduce reflections in water, and make foliage more vibrant.
   • Architecture: Minimize reflections on glass buildings.
   • Outdoor Portraits: Improve skin tones and overall image quality.
   • Filmmaking: Achieve cinematic effects by controlling reflections.

7. Packaging and Accessories:

   • Each filter comes with a plastic case for safe storage.
   • A cleaning cloth is included to keep your filter pristine.

Remember, the QuartzLine CPL filter is an investment in both image quality and durability. Whether you're shooting in bright sunlight or overcast conditions, having a high-quality CPL filter can significantly enhance your photography and videography.
