Technical Specifications: Precision Down to the Micron

Towin’s Apochromatic Low Distortion Lenses are meticulously designed to deliver exceptional performance across critical parameters:

• 1. Focal Length Range: Available in 8mm, 12mm, 16mm, 25mm, and 35mm variants, these lenses cater to diverse applications, from close-up inspections to wide-field surveillance.
• 2. Aperture (F/#): Fixed at F/2.8, ensuring optimal light transmission while maintaining sharpness even in low-light conditions.
• 3. Distortion Control: Less than 0.1% geometric distortion, guaranteeing straight lines remain unaltered—critical for applications like 3D reconstruction and quality control.
• 4. Chromatic Aberration Correction: Apochromatic design corrects red, green, and blue wavelengths to converge at a single focal point, eliminating color fringing and enhancing contrast.
• 5. Resolution: Supports resolutions up to 5 megapixels, with a modulation transfer function (MTF) exceeding 70% at the center and 50% at the edges.
• 6. Mount Compatibility: C-mount standard, with options for F-mount and M42 mounts to integrate seamlessly with various cameras and sensors.
• 7. Working Distance: Ranges from 10mm to 200mm, depending on the focal length, enabling flexibility in setup configurations.
• 8. Coating: Multi-layer anti-reflective coating minimizes flare and ghosting, ensuring crisp images even in challenging lighting environments.
