Lenses usually refer to the optical elements that diverge or converge the beam of light. Lenses can be widely used in security systems, vehicle-mounted systems, digital cameras, lasers, and optical instruments, while playing a significant role in astronomy, military, transportation, medicine, and other fields. OMTOOLS provides or customizes positive and negative lenses (including plano-convex, biconvex, meniscus, plano-concave, and biconcave) for different bands, with different focal lengths and apertures made of K9, fused silica, and other materials to meet diversified commercial and scientific uses.
