Lens Specifications and Performance

Shanghai Optics’s wide spectrum fisheye lens features a focal length of 1.2mm, an F number of 2.8, and a remarkable Field of View of 175°. Noteworthy for its exceptional optical resolution nearing the diffraction limit, Shanghai Optics’s lens sets a new standard for image quality in scientific imaging applications.

Shanghai Optics’s lens maintains F-θ distortion under 2%, ensuring precise acquisition of target position information from the image. This meticulous control guarantees a spot RMS radius smaller than the pixel size within 95% of the field of view, crucial for maintaining image accuracy in scientific observations.

Shanghai Optics’s lens design effectively corrects distortion by adjusting vignetting to counteract aperture aberrations, ensuring high image quality across the entire field of view. This optimization of image uniformity is especially critical in fisheye lenses where distortion and aperture aberrations can compromise image clarity.

Shanghai Optics’s lens excels in controlling chromatic aberration within a range of 0.04mm, surpassing industry standards. Maintaining chromatic aberration dispersion within a pixel range, Shanghai Optics’s design guarantees high-quality images across various wavelengths, preserving the accuracy and clarity of scientific observations.
