Fisheye Lenses
Typically fisheye lenswith good fisheye lens designhas a front lens group of a greater negative refractive power than an ordinary inverted telephoto wide angle lens, with a large back focal distance. Its extreme power distribution will cause great field curvature in the transmitted image. As fisheye lens leads to significant barrel shaped distortion, to improve field curvature and astigmatism, it is necessary to compose a doublet to avoid significant negative deviation and provide correction of chromatic aberration.
Hyperion Optics designers’ expertise contributes various range of fisheye lenses customized projects, from sminiature fisheye lense used for 360 degree viewing device to 200mm in diameter dome projection fisheye lenses. Our fisheye lens database provides design result and simulations for full frame fisheye lens, circular image (hemispherical) fisheye lenses with different fisheye lens focal lengthoptions.
During HYP designprocess, our designers evaluate relative illumination performance by utilizing real ray trace analysis, vignetting is also used to control off-axis aberrations due to a half stop or full stop in relative illumination is tolerable in conventional photography scenario. Distortion departure from f-theta mapping is also critical in our design phase, according to the initial simulation and calculation; our designers are able to adjust and optimize to reach an ideal solution. We also look into lateral color which is the lateral shift on the image plane intersection between the shortest wavelength chief ray and the longest wavelength chief ray by real ray trace analysis.
