摘要

在简单设计的双频红外物镜中实现优越的光学特性和被动热化的可能性。特别是通过在光学方案中使用硫系玻璃制成的折射透镜来确保这一点。给出了有关光学方案布局和获得后续优化的初始设计参数的建议。在- 40°C ~ + 60°C的工作温度范围内，设计了一种工作在中长红外波段的超孔径折射透镜物镜，并在非冷却微辐射热计的矩阵上形成了高质量的多色图像，结果证实了这些建议的可靠性和有效性。

Designing dual-band athermal refractive-lens IR objectives

The possibility of achieving superior optical characteristics and passive athermalization in dual-band IR objectives of a simple design is shown. This is ensured, in particular, by using refractive lenses made of chalcogenide glasses in the optical scheme. Recommendations regarding the layout of the optical scheme and obtaining initial design parameters for the subsequent optimization are given. The reliability and effectiveness of the recommendations are confirmed by the results of designing a super-aperture refractive-lens objective operating in the mid- and long-IR subranges and forming a high-quality polychromatic image on the matrix of an uncooled microbolometer in the operating temperature range from – 40°C to + 60°C.
