Singlet lens is a lens consisting of a pure single element, which can be considered as the fundamental element of developing optical systems. Based on optical engineersâ?? design, multiple singlet lenses might be utilized within an optical system with other optics. As the basic optical element, singlet lenses are commonly used in engineersâ?? design, and further assembly works for a variety of applications such as imaging collimating. At hyperion optics, our manufacturing capability covers plano concave/convex, bi-concave, bi-convex, positive and negative meniscus, ranged from many variations of optical glass and fused silica and even crystal. With our reliable coating technique, ar or v-coatings can be applied to reach expectation. Special treatment i.E.
