Ultra Wide No Distortion lenses with patented Linear Optical Technology®

Theia’s family of ultra wide angle lenses use patented Linear Optical Technology® to create ultra-wide fields of view and correct barrel distortion, keeping straight lines straight in the image. The award-winning technology increases resolution at the image edge and improves the probability of recognizing and identifying an object without software and its inherent latency, making it ideal for any application requiring real time imaging of wide fields of view without distortion, even from close range

• Up to 135° HFOV in fixed and varifocal models
• Multi-megapixel, with up to 4K compatible resolution
• Near IR corrected and visible only versions
• Manual and DC auto-iris options
• CS or C mounts available
• For 1/2.3” image sensor formats or smaller

 There are four lens series using patented Linear Optical Technology®

-         MY125 / SY125 is the widest lens with 1.3mm focal length, providing up to 135° horizontal field of view, 200 lp/mm resolution, in visible only, for up to 1/2.5” sensors. Offered with manual or DC auto iris, and C and CS mounts.

-         MY110 / SY110 1.7mm focal length lens provides up to 120° horizontal field of view, 160 lp/mm resolution, is NIR corrected from 435 – 940nm, for up to 1/2.5” sensors. Offered with manual or DC auto iris, and C and C mounts.

-         The varifocal ML183 / SL183 with 1.8-3mm focal range provides up to 116° horizontal field of view, 200 lp/mm resolution, is NIR corrected from 435 – 940nm, for sensors up to 1/2.3”. These are offered with manual or DC auto iris, in C and CS mount versions.

-         The MY23F 2.2mm fixed focal length lens provides up to 116° horizontal field of view, 200 lp/mm resolution, is NIR corrected from 435 – 940nm and works for sensors up to 1/1.8”. Currently available in a combination C/M12 mount. Read a Case Study about this lens being chosen for automotive crash tests for their wide field of view, low image distortion. 

Ultra wide field of view

Theia’s lenses provide an ultra wide field of view of up to 135º horizontally, as much as 70% greater field of view than other wide angle lenses available, allowing the user to take full advantage of the capabilities of today’s megapixel cameras. With a multi megapixel camera, Theia’s lenses enable a greater HFoV with the same or fewer cameras. Theia’s lenses allow installation and maintenance of fewer cameras while still covering a large surveillance area.

Distortion Correction

Theia’s patented Linear Optical Technology® is a real time, all-optical distortion correction technology that creates an ultra wide field of view while correcting barrel distortion in the lens itself, without the use of software or its inherent latency. Other wide angle lenses show barrel distortion, compressing the image at the edges and reducing resolution; Theia’s technology maintains linearity in the image increasing object size and resolution at the image edges, increasing the probability of recognition and identification compared to other wide angle lenses.

NIR correction with Multi-Megapixel Resolution

Some models are offered with NIR correction from 435nm to 940nm, focusing visible and NIR spectrum light to the same image plane with minimal focus shift. When switching from daylight to NIR illumination, Theia’s IR corrected lenses maintain their megapixel resolution performance. The optimized field flatness and IR correction for Day/Night allows the image to be in sharp focus from center to edge under many different light sources. Theia’s lenses use the latest aspherical lens manufacturing technology, low dispersion glass types and proprietary anti-reflective coatings to create this combination of multi megapixel resolution and NIR performance, a combination of features found in few other lenses on the market today.
