Hyperion Optics upgraded our edging device in spherical lens components manufacturing process, we now are able to provide +0/-0.01mm in diameter tolerance control for your precision demand. Please contact our sales if you have tight diameter parameter to deal with. Spherical Lenses 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 engineers' 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 engineers' design, and further assembly works for a variety of applications such as imaging collimating. At Hyperion Optics, our manufacturing capability covers Plano-Convex/Concave, 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. edge blackening / special packaging / labeling also available upon request. Our singlet lenses production competency helps our customers to build their unique and cutting edge applications such as microscopy device, diameter 2.5mm~3.5mm design, for projection/ observation applications, we can deliver 180+mm in diameter singlet lens. Besides regular visible spectrum singlet lenses, NIR / SWIR/ MWIR / LWIR lenses are also available at our facility, please refer to our IR optics for more information. For extremely precision sensitive system requirement, please contact us for further information, our engineers are more than happy to evaluate your design and have our experiences of manufacturing input help to define the most appropriate tolerances.
