A fixed focal length lens for the short-wave infrared (SWIR) market delivers reliable, repeatable imaging results with the added benefit of having a stable and uniform focus and optical quality. The SWIR fixed focal length lens is designed to be used in applications where accuracy is paramount. These lenses are typically utilized in industrial inspection/research/monitoring scenarios, where the performance of lenses must remain consistent over a variety of lighting and atmospheric conditions. By having a fixed focal length, the SWIR fixed focal length lens has less complexity and therefore provides more consistency and dependability when delivering results. In addition, the SWIR fixed focal length lens's ability to create clear details in harsh
