Theia's SL940 for LPR

Theia Technologies' SL940  telephoto lens can be a cost effective solution for License Plate Recognition (LPR).  With the SL940 lens at 40mm focal length you can get 45 pix/ft. at approx. 290 ft. away when using a HD 1080p resolution camera.   


And the 5 megapixel lens is IR corrected so there is very little focus shift with nighttime usage.  See example images in both lighting conditions on our website.  The lens is available in Manual, DC Auto and P-iris versions. 

Find detailed specifications here, or contact us at to learn more. 

Theia P-iris Lens Availability
Two camera companies are planning to release  cameras or camera firmware SL940P  
upgrades to allow use of Theia's new SL940P P-iris lens.  Watch for announcements in the coming weeks about when this lens will be available and with which cameras.
The P-iris, or Precise iris, provides more precise iris control which enables greater depth of field, heightened contrast, improved  image sharpness and clarity, and helps to optimize megapixel camera images.  Learn more about this lens here.
