IM 1.6 is index matched to glass, so it creates a void black absorber for situations when light travels through glass and no internal reflection is desired. In contrast to Singularity Black, which is index matched to air, IM1.6 provides an absorbing coating for glass and other optics. Nanolab staff can adjust the paint's refractive index from 1.55 to 1.75 for exact requirements.
IM1.6 can be applied by spray coating, dipping, or brush. The formulation contains carbon nanotubes, a solvent and a binder phase suited for adhesion to glass. Sold in 200ml jars. Due to the flammable solvent, note that this product ships as a hazardous material.
