A linear polarizing filter is an optical filter that effectively eliminates reflected light and glare from non-metallic surfaces and enhances color saturation by filtering light rays with specific vibration directions. It is suitable for older manual-focus film cameras and some scientific and industrial applications.
Model: Customized
Specifications: Customized
Material: optical glass
Core Functions
Eliminate Reflections: Eliminates reflections from non-metallic materials such as surfaces, glass, and painted surfaces, making obscured objects (such as items in a shop window or underwater rocks) clearly visible.
Enhance Color Visibility: By filtering out saturated light from the sky and other environmental elements, it makes blue skies appear bluer, white clouds stand out more, and enhances the overall color contrast and depth of the image.
Alternative Neutral Density Filter: Reduces light intake by approximately 1-2 stops. In specific situations, it can be used as a simple neutral density filter to help control exposure.




Product Features
High-Efficiency Polarization: Utilizes the principle of linear polarization to directly filter polarized light, resulting in high optical efficiency.
Rotation Adjustment: The filter’s front frame can be rotated, allowing you to observe through the viewfinder and rotate to the optimal angle to achieve the desired ablation or color enhancement effect.
Compatibility Notes: A key characteristic is that linear polarizing filters may interfere with the autofocus and metering systems of modern digital and automatic film cameras, causing malfunctions or errors.
Important Precautions (Main Difference from CPL Filters)
This product is a linear polarizing filter (PL), not a circular polarizing filter (CPL).
Do not use this product on modern SLR cameras that rely on phase detection autofocus and most autofocus cameras, as this may lead to focus failure or inaccurate metering.
This product is suitable for: manual focus cameras, rangefinder cameras, some mirrorless cameras (compatibility needs to be confirmed), and non-photographic applications such as scientific instruments, measuring equipment, and laser optics experiments.
A linear polarizing filter is a basic and highly efficient polarizing filter that effectively controls reflected light and enhances image contrast within compatible photographic equipment or specific professional fields. Before selecting, please ensure your device supports the use of a linear polarizing filter.
