Near Infrared Absorber

Description of the Near Infrared Absorber

Plastic laser welding is a new plastic processing technology. It originated in 1970 with carbon dioxide laser welding plastic film, when lasers were first demonstrated as being suitable for welding plastics. But because the carbon dioxide laser is very cumbersome and the transmission performance is poor, the operation is very inconvenient. And as the diode laser and semiconductor laser became more popular, the carbon dioxide laser gradually withdraws from the field of plastic welding.

The right laser absorber

The diode laser has a wavelength of 800 ~ 1000nm and the semiconductor laser has a wavelength of 1064nm, both in the near infrared range. In this wavelength range of the near-infrared, most plastics are transparent and both lasers can penetrate the plastic very easily. This means that finding a suitable laser absorber is important to further develop plastic laser welding technology.This absorber must meet the following conditions:Strong absorption of 800 ~ 1064nm infrared light;Very stable under heat of at least 300 ℃;Good dispersion, compatible with polymer materials;High visible light transmittance that can be used with different pigments.Omnistab NIR is a disperion of nano particles in an organic carrier. The particles absorb solar irradiation in the Near Infrared region. The absorption spectrum can be adjusted to customer requirements.
