To meet the needs of the virtual reality market,use ZEMAX to design a compact panoramic lens.There are two fish-eye lenses in the system which works in visible light range,the field of view of lens is 200 degree and the F number is 2.8. A prism is added to the lens group to achieve a 90 degree turn of the rear lens group and then a 360-degree panoramic camera system is constructed by combining optical paths.This method effectively reduces the system volume.For the image sensor, Sony’s IMX159 chip is used, with a resolution of 4608 (H) × 3456 (V), a total of 16 million pixels, and a pixel size of 3.76 μm.The design result show that in the full field of view ,the system's MTF value at 90 lp/mm is greater than 0.3, and in the center field of view the value is greater than 0.7. The size of all field spot’s root-mean-square(RMS) are smaller than the smallest pixel of the detector, the relative illuminance of the system is greater than 50% in the full field of view and all other indicators also meet the requirements.
