Abstract
The present invention relates to apparatus and/or methods for sanitising objects comprising a UV light source for emitting a beam of UV light and are particularly suited to sanitising a plurality of objects such as banknotes and mail at high and variable frequencies. The apparatus and/or method may be applied to reduce a concentration of drug substance on the surface and/or to reduce microorganisms and/or viruses on the surface of each of the plurality of objects.
Claims49
A method for sanitising a surface of an object, comprising:
- conveying the object through UV light from an excimer laser at a speed of greater than 1.0 m/s, such that the UV light irradiates the surface,
- wherein the UV light has a wavelength, intensity and pulse duration sufficient to reduce a concentration of drug substance on the surface.
A method for sanitising a surface of an object, comprising:
- conveying the object through UV light from an excimer laser at a speed of greater than 1.0 m/s, such that the UV light irradiates the surface,
- wherein the UV light has a wavelength, intensity and pulse duration sufficient to reduce microorganisms and/or viruses on the surface.
An apparatus for sanitising a surface of one or more objects, comprising:
- an excimer laser that emits pulses of UV light;
- and
- a system that conveys the object(s) through the UV light at a speed of greater than 1.0 m/s, optionally between 1.0 m/s and 8.0 m/s;
- wherein the UV light has a wavelength, intensity and pulse duration sufficient to reduce a concentration of a drug substance on the surface and/or reduce microorganisms and/or viruses on the surface.
