This study explores the design and refinement of a Mid-Wave Infrared (MWIR) continuous zoom lens system, which is coupled with a high-definition detector. Tailored to operate within a focal length range spanning 36-550 mm and offering a resolution of 1280 x 1024 pixels, MWIR imaging serves as a cornerstone in surveillance, defense, and remote sensing applications. Leveraging advanced optical design methodologies, this research aims to achieve heightened imaging resolution, mitigate aberrations, and counteract narcissus effects throughout the zooming spectrum. Furthermore, through meticulous manufacturing optimization, the production process is streamlined, ensuring cost-effectiveness and efficiency. The resultant MWIR zoom lens system showcases remarkable performance enhancements, promising superior image quality, and positioning itself as a versatile solution for diverse MWIR imaging endeavors.

A simple method developed to solve the problem oj kinematics detemlination of four~componel!/ electronically compensated zoom lenses is described. It has beel/ shawl! that a simple paraxial conjugate equation. along with magnification equation can be used successfully to solve the complex problem oj component displacemelll ill a four-component electronically compensated zoom lens. This method provides a deep insighr into the image jonnation process by a zoom lens. The method developed is simple fa program and provide excellent injonnalion about working of jour-component electronically compensated zoom lenses.
