Double-Layered Use is Recommended for Extremely Sensitive Applications
This black rubberized fabric provides an easy method for protecting light-sensitive equipment, as the rubberized coating prevents light from penetrating through the weave of the fabric. Double-layer use is recommended for extremely sensitive applications. Please note that this material is not intended for use as a laser curtain since it is not flame retardant. The fabric has also not been tested for clean room compatibility.
We can cut this material into custom lengths (in yards) that fit your application. Please contact Tech Support for a quote.

Upon request, we can offer custom sizes up to 48" x 48" (121.9 cm x 121.9 cm) to customers in North America, or up to 44" x 32" (111.8 cm x 81.3 cm) elsewhere. Please contact Technical Support for a quote.
Flocked paper is a self-adhesive material made of many fine fibers. It has a textured, matte-black surface. When viewed at from low angles, it absorbs virtually 100% of the visible light that strikes it. The fibers will not shed dust or lint, unlike some velvet and felt materials. The approximate compressed thickness of the flocked paper is 0.015" (0.381 mm) with the backing and 0.012" (0.305 mm) without the backing.
Image contrast can suffer due to stray light reaching the focal plane of many applications where the light path travels through a tube or other enclosed area. Applying a flat-black paint to the inside may help, but a textured matte-black surface is a much more effective light trap.
Caution: Do not cut the BFP1 black flocked paper with a laser cutting tool, as the BFP1 burns easily and may catch fire. It is suggested that you use a utility knife or other sharp edged tool to cut the BFP1.
This durable, lightweight foil has a matte black finish to absorb light from any ambient or conventional light source. It can be molded quickly to form blackout covers, dark rooms, laser channels, or other configurations so as to mask light leaks or eliminate unwanted reflections. Secure its position using tape, stables, or adhesives. This black aluminum foil is sold on a role and measures 1' x 50' (305 mm x 15.2 m).

High-Performance Black Masking Tape

Black Masking Tape
Thorlabs offers two types of black masking tape and an aluminum foil tape. All types of tape can be torn by hand, are easy to remove, and do not leave residue. The T137-1.0 and T137-2.0 black masking tape can be used for general applications. For applications requiring minimal ambient light transmission, the T743-1.0 or T743-2.0 high-performance black masking tape is recommended. For total blackout requirements or high-power applications, we offer the T205-1.0 or T205-2.0 non-reflective, flame-retardant aluminum tape. This foil tape has been tested to withstand up to 10 seconds of exposure from a 20 W, Ø6 mm, 10.6 µm laser beam.
In the photographs shown above, a collimated LED (Item # M530L2-C2) with approximately 170 mW output power was used to illustrate how the T743-2.0 high-performance tape allows very little light transmission as compared to the T137-2.0 standard black masking tape. The table below gives the measured power and percent transmittance when various wavelengths of light were incident upon each type of tape.

Conventional Roller Blind Chain Operating System
These blackout blinds are made from a black, rubberized fabric. Designed for applications where light exclusion is required, such as laboratories and dark rooms, they can be used to keep stray light out of photosensitive setups. They are also useful for preventing bright sources such as lasers from being visible by people outside the lab. The fabric is totally opaque, and the blinds are manually operated by a side chain. They can be attached to the wall or window recess using the two brackets and four screws that are supplied. Please note that the blinds are not intended for use as a laser curtain since the material is not flame retardant. The material has also not been tested for cleanroom compatibility.
