ZnSe positive meniscus lenses are used to decrease the focal length of another lens while maintaining the angular resolution of the optical assembly. These lenses are commonly used to achieve tighter beam focusing when paired with another positive lens. These lenses are available uncoated or with an antireflection coating optimized at 8~12μm.
