Acktar Light Absorbent Foil and Film
• Diffusive or Specular Reflectance
• Extremely Wide Band Performance from the UV to IR
• Standard, Low Outgassing, and No Adhesive Options
Acktar Light Absorbent Foil and Film is used to eliminate light reflectance in applications where the direct
coating of parts is not practical, including optical packaging, laser devices and platforms, IR systems, or
passive thermal control. Acktar Light Absorbent Foil and Film features high emissivity with low reflectance,
low outgassing, excellent biocompatibility, a broad operating temperature range, and compatibility with class
1 cleanrooms. Acktar Light Absorbent Foil and Film is available in pre-cut patterns or as large sheets for
custom patterns.

Velvet-like, adhesive or non-adhesive backing choices allow black-out material to be applied to any acceptable
surface. Flocked material surface characteristics are consistent across product line, but higher paper numbers
indicate thicker, more durable levels of backing for the material.

• Coated for High Absorbance of Laser Light
• Tubular Beam Trap or Thin, Flat Beam Block Designs
• M6 Tapped Hole for Easy Post Mounting
Acktar Blackened Laser Beam Traps and Blocks feature proprietary coatings designed to absorb incident
laser light from the ultraviolet (UV) to the long-wave infrared (LWIR) spectrums. These Acktar coatings can
achieve a reflectivity factor of less than 10-6 (beam trap designs) and have laser damage thresholds up to 20
W/cm2. An M6 tapped hole on both the beam trap and beam block designs allows for easy mounting to optical
posts for integration into optical systems. Acktar Blackened Laser Beam Traps and Blocks are available
in multiple sizes to accommodate small or large laser beams, increasing overall lab safety by reducing the
risk of laser damage. The Flat Beam Block design features back screws for a 92 mm cooling fan attachment,
allowing for multiple blocks to be coupled to cover large areas.
