In today's rapidly evolving technological landscape, machine vision, factory automation, and robotics play crucial roles across diverse industries. The accuracy and efficiency of these systems depend heavily on the quality of their optical components, particularly lenses. Theia Technologies offers a comprehensive range of high-performance lenses specifically designed to meet the demanding requirements of these applications.
A defining characteristic of Theia's lenses is their utilization of patented Linear Optical Technology®. This innovative approach addresses a critical challenge in wide-angle imaging: barrel distortion. Traditional wide-angle lenses often produce images where straight lines appear curved, hindering accurate measurement and analysis. Theia's Linear Optical Technology® corrects this distortion optically, within the lens itself. This optical correction offers a significant advantage over software-based correction methods, which introduce latency (delay) in processing. By eliminating this latency, Theia lenses enable faster and more accurate X-Y mapping of objects within the image, a crucial factor in real-time machine vision and robotic control. Furthermore, Theia's near-IR corrected, Day/Night lenses are particularly well-suited for multi-spectral applications, expanding their versatility in various lighting conditions and imaging scenarios.
Theia offers a diverse selection of lenses to cater to a wide range of application needs. These lenses boast a number of key features:
Fixed and Varifocal Options: Theia provides both fixed focal length lenses for specific applications and varifocal lenses that offer adjustable focal lengths for greater flexibility.
Ultra-Wide Field of View: With horizontal field of view (HFOV) options up to 135 degrees, Theia lenses capture expansive scenes with minimal distortion.
High Resolution: Supporting 4K and 4K-compatible resolutions up to 12 megapixels and 300 lp/mm, these lenses deliver sharp, detailed images essential for precise analysis.
Multi-Spectral Capabilities: Available in visible-only and near-IR corrected versions, Theia lenses cater to diverse spectral requirements, including day/night surveillance and specialized imaging applications.
Iris Control Options: Offering manual, P-iris, and DC auto-iris versions, Theia lenses provide flexibility in controlling the amount of light entering the camera.
Sensor Compatibility: Designed for various image sensor formats, including 2/3", 1/1.7”, 1/2.3”, and smaller, Theia lenses can be integrated with a broad range of cameras.
Motorized Options: Depending on the specific model, fully motorized options are available, enabling remote control of zoom, focus, and other lens parameters.
Mounting Options: Available in C mount (as well as CS) and some board mount versions, Theia lenses offer compatibility with various camera mounting standards.
To further assist users in selecting the appropriate lens, Theia provides a wealth of resources, including a downloadable machine vision lens catalog, sample requests, CAD downloads, and informative videos.
