Theia lenses bring ANPR/LPR into focus

At the Vision 2018 show in Stuttgart, the company showed off for the first time its ML610M 6-10mm varifocal lens with 4k resolution, NIR correction for a 2/3” sensor covering the focal range of three prime lenses with up to 87 degrees horizontal field of view.

The telephoto lens portfolio is most popular for long-distance, high-detail applications such as ANPR/LPR and tolling, the company says, with 4k and 5+ megapixel resolutions maintained even in near IR light.

Mark Peterson, VP advanced technology at Theia, says: “Theia lenses are particularly good in NIR illumination with only a 5 micron focus shift, making reading number plates in low light and bad weather conditions an easier task.”

The company has models with Precise iris, or P-iris for improved depth of field and says that the lenses are “very compact for their telephoto focal range, size format and full feature capability, including models with motorised zoom, focus and IR cut filter”.
