Product Family Description

  • 38% Transmission of Unpolarized Light
  • Laminated for Increased Durability
  • Good Color Reproducibility

Visible Linear Polarizing Laminated Film is manufactured using a precision method of aligning long chain polymers to produce high transmission polarizers, with extremely good color reproducibility. To increase durability and stiffness, the film is laminated in cellulose triacetate (CTA). The sheets are neutral gray in color.

Visible Linear Polarizing Laminated Film is ideal for a range of microscopy, display, and imaging applications. A single sheet features 38% transmission of unpolarized light. When two sheets are crossed, transmission reduces to 0.74%. If used at 550nm, the crossed transmission is less than 0.01%. 

Note: The transmission axis is parallel to the first dimension listed. Dimensions and dimensional tolerances represent the active (polarized, gray) section of the material and do not include the machine edge that exists along the width of the material. Protective film on both sides of the material needs to be removed before first use.
