Abstract
A system for determining the presence and optionally the position of an ophthalmic product such as a contact lens in a container is provided.
Claims24
An apparatus for detecting the presence or position of an ophthalmic product in a container, comprising:
- (a) source of electromagnetic energy located relative to the container to direct electromagnetic energy at the container;
- (b) a detector disposed relative to the container and the source to detect electromagnetic energy from the source which passes through or is reflected by the product and the container;
- and
- (c) a processor for determining the presence or position of the product in the container responsive to fluorescence, absorption or reflection of the electromagnetic energy by the product.
An apparatus for detecting the presence of an ophthalmic product in a container comprising:
- (a) a source of electromagnetic energy located relative to the container to direct electromagnetic energy at the container;
- (b) a reflective surface located such that the container is displaced between the source and the reflective surface;
- (c) a detector disposed relative to the container and the source to detect electromagnetic energy from the source which is reflected by the product, the container, and the reflective surface;
- and
- (d) a processor for determining the presence or position of the product in the container responsive to the fluorescence, absorption or reflection of the electromagnetic energy by the product.
A method for detecting the presence or position of an ophthalmic product in a container, the product including a media which fluoresces, absorbs or reflects the electromagnetic energy of a frequency in a specified range, the method comprising:
- (a) directing electromagnetic energy at the product and the container;
- (b) detecting the absence of or reduction in electromagnetic energy of a frequency in a specified range which passes through or is reflected by the product and the container;
- and
- (c) processing the detected electromagnetic energy to determine the presence or position of the product in the container.
