Ruth's sister 30x20cm Linear Polarizing Film Sheet internal power cable

SKU CH-9NAG-W4ZMB

A 30x20cm linear polarizing film sheet with 99.99% efficiency and 42% single transmittance for physics experiments and imaging applications

  • High contrast linear polarizer for clear imaging
  • 42 % single transmittance across 380–700 nm spectrum
  • 99 % polarizing efficiency blocks unwanted glare
  • 30 × 20 cm neutral gray sheet fits LCD panels
  • Thin 0.25 mm TAC+PVA film handles easily

Polarizing Film Sheet 30x20cm

This linear polarizing film sheet measures 30x20cm and uses TAC+PVA material with a neutral gray finish. It provides 99.99 percent polarizing efficiency across the 380 to 700nm wavelength range. The sheet is designed for educational physics, photography and imaging experiments.

Upgrade from basic filters

The high contrast transmissive optical type delivers 42 percent single transmittance and only 0.005 percent crossed transmittance. This jump is worth it when you need precise polarization control for birefringence studies or light scattering demonstrations. Standard filters cannot match this extinction ratio.

Check your setup before ordering

Verify that your application requires a linear polarization axis of 50mm and a film thickness of 0.25mm. Ensure the 30x20cm dimensions fit your optical holder or experimental frame. Allow for a 0 to 1cm measurement tolerance due to manual cutting.

Questions about this item

Will the 30x20cm sheet fit inside my LCD panel frame?

The film measures approximately 30cm by 20cm with a thickness of 0.25mm, so check your panel's internal clearances against those dimensions.

How do I install the polarizing film without damaging the TAC+PVA layers?

Clean the LCD surface thoroughly, align the 50mm polarization axis, then apply the 0.25mm sheet slowly to avoid bubbles; the 150µm film thickness makes it prone to creasing if rushed.

When will the 99.99% polarizing efficiency degrade enough to need replacement?

The TAC+PVA material maintains 42% single transmittance and 0.005% crossed transmittance across 380-700nm; replace if contrast drops or neutral gray color shifts noticeably.
