Polarizing Filter Sheet B+W 1093942 400×400×0.3 mm – B&W polarizer film

B+W polarizing filter sheet model 1093942 is a 400×400×0.3 mm polarizer film manufactured by B&W. The sheet is designed to reduce glare and reflections, enhance image contrast and color saturation, and control linearly polarized light in photography, optical testing and various industrial applications. Its thin 0.3 mm profile makes it suitable for cutting to size, mounting into custom filter holders or integrating into lighting setups and experimental optical assemblies where precise polarization control is required.

Advantages

The polarizer film delivers reliable linear polarization across its surface and helps suppress unwanted reflections from non-metallic surfaces such as glass, water and polished plastics. Its uniform thickness and optical flatness support consistent image quality when used in camera rigs or lab equipment. The flexible sheet can be trimmed or layered for variable attenuation without compromising the polarizing function, making it practical for custom filter fabrication and retrofit applications.

Suitable for

• Photography: reducing reflections and increasing contrast for landscape, product and architectural photography
• Optical testing and laboratory setups requiring controlled linear polarization
• Lighting systems where glare control and polarization are needed
• Industrial inspection and imaging where surface reflections interfere with measurements
• Custom filter manufacturing and DIY camera rigs

Key specifications

• Dimensions: 400 × 400 mm
• Thickness: 0.3 mm
• Type: linear polarizer / polarizing film
• Form factor: flexible sheet suitable for cutting and mounting
• Optical characteristic: reduces reflections and controls polarized light

How to use

Cut the polarizer sheet to the required dimensions using a straightedge and a sharp blade or precision cutter. Mount the trimmed piece in a filter holder, frame or between glass plates depending on the application; ensure the mounting surfaces are clean to avoid introducing scratches or dust. For photographic use, rotate the polarizer relative to the scene or light source to adjust the degree of polarization and obtain the desired reduction of reflections or enhancement of contrast. When integrating into optical experiments, align the transmission axis according to the polarization orientation required by the setup.

Usage recommendations

Handle the film by the edges and store it flat between protective sheets to prevent scratches. Avoid exposing the sheet to high heat or solvents that could damage the polarizing layer. Test a small cut piece when layering or bonding to verify adhesion and optical performance prior to final installation.
