• High Contrast, Refl ective Design
• Excellent Visible and NIR Performance
• Superior Durability Under High Temperatures and Humidity
TECHSPEC® Wire Grid Polarizing Film is ideal for applications requiring high contrast polarization, including
pico projectors, polarizing beamsplitters, and heads up displays. TECHSPEC® Wire Grid Polarizing
Film is designed to transmit the required polarization state while refl ecting the unwanted state. Since these
polarizers have spectrally fl at performance at angle of incidences up to 45°, they can also be used as polarizing
beamsplitters. Additionally, TECHSPEC® Wire Grid Polarizing Film features excellent durability in high
temperature or humid environments and provides excellent performance in the visible and NIR spectra from
400 - 1200nm. Note: Due to the wire grid being exposed, special care should be taken when handling to prevent
damage to the polarizer.

• Ideal for NIR Polarization Applications
• >400:1 Extinction Ratio from 800 - 2200nm
• High Effi ciency Across Wavelength Range
Near-Infrared (NIR) Linear Polarizing Film consists of a durable polymer substrate and is ideal for imaging
applications that range from the visible to NIR (400 - 2200nm). This polarizing polymer fi lm features
an excellent average transmission of 39% with greater than 99.6% polarization effi ciency for incident randomly
polarized light between 760 and 2200nm. Multiple rectangular sizes are available to accommodate
light sources that range from low power NIR lasers with small beam diameters, to larger LED light beams.
Near-Infrared (NIR) Linear Polarizing Film is used in industrial imaging and laboratory applications, i.e. to
attenuate the intensity of low output NIR lasers and LEDs or to reduce glare in images recorded using NIR
photodetectors. The polarization axis is labelled on the protective masking of the polarizing polymer fi lm.
Note: Remove protective masking before fi rst use.

Visible Linear Polarizing Laminated Film
• 38% Transmission of Unpolarized Light
• Laminated for Increased Durability
• Good Color Reproducibility
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 0.04%. If used at 550nm, the crossed transmission is less than 0.01%. Two sheets can also be
used as a variable attenuator. Note: For sheets, the transmission axis is parallel to the fi rst dimension listed.
