Design of a Miniaturized Infrared Wide-Angle Lens
In order to meet the requirements of modern intelligent equipment and infrared interactive identification, we design a miniature infrared wide-angle lens by CodeV and Zemax optical design software. The lens is equipped with three plastic lenses and one infrared band pass filter. Its optical structure is negative-positive-positive. The design results show that F number is 2.2, the maximum viewing angle is 129° and the mechanical total length is 3.8 mm. Modulation transfer function (MTF) value of all fields is larger than 0.5 at 1/2 Nyquist frequency. The assembled lens is tested to show that MTF performance meets design requirements and the infrared detection function can be achieved.
