Ir Light Absorbing Foil

Light absorbent foil and film used to eliminate unwanted stray light in applications such as laser devices or infrared systems is available at edmund optics.

Ir light absorbing foil. Ultra di usive light absorbing foil uv vis and ir metal velvettm metal velvettm 光吸収膜メタルベルベットタイプは 紫外 可視 赤外光において 弊社光 吸収膜シリーズで最も反射率が低い光吸収膜タイプです グレージング角 への. Just as sunglasses absorb the harsher parts of sunlight many materials absorb the longer infrared ir wavelengths that are invisible to the human eye. Showing all 8 results. For a period of 6 months from the date of rst sale acktar use this.

This is an ideal solution for very large quantities over sized part areas and for contaminated environments where the light absorbing surface needs to be periodically renewed. Acktar vis and ir light absorbing foil spectral blacktm and spectral black hptm the data should be considered typical representative only limited warranty. The rohs compliant material features high emissivity with low reflectance low outgassing and offers compatibility with class 1 cleanrooms. Acktar light absorbent foil features a spectral absorbance of 99 99 and provides extremely wide band performance from the ultraviolet uv to the ir for excellent versatility.

The light blocking material can now be obtained in running meters. With specular absorbance as high as 99 99 and wide band performance the metal velvet coated light absorbing foil is a stray and scattered light absorbing suppressing material available to optical engineers. At just the right temperature light blue line the reflectivity of the device drops almost to zero 99 75 absorbance for infrared light at a wavelength of 11 6 µm. Acktar lichtabsorbierende folie verhindert eine lichtreflexion in anwendungen bei denen eine direkte beschichtung der teile unpraktisch ist beispielsweise bei optical packaging lasergeräten und plattformen ir systemen.

Some ir absorbing materials you see every day include window glass plastics metals and wood. The black foil coating available either with or without an adhesive backing as sheets die cuts or roll.
