Product Description
Product Description
Optical Lenses are optical components designed to focus or diverge light, widely applicated from microscopy to laser processing. A Plano-Convex or Double-Convex lens causes light to focus to a point, while a Plano-Concave or Double-Concave lens diverges the light which traveling through the lens. Achromatic Lenses are ideal for correcting color, aspheric lenses are designed to correct spherical aberration.Ge, Si, or ZnSe lenses are suited for transmitting the Infrared (IR) spectrum, fused silica is well suited for the Ultraviolet (UV).
Meniscus Lenses
Germanium Meniscus Lenses are designed for demanding infrared applications including infrared imaging or surveillance, remote sensing, or infrared spectroscopy. These meniscus lenses are offered uncoated or anti-reflection coated for increased performance in the designated coating wavelength range.
Shenyang Ebetter Optics Co., Ltd. offers standard and high precision optical windows in round,square, wedge shapes. We also support custom made optical windows in a variety of substrates, such as UV Fused silica, N-BK7, Germanium(Ge), Silicon(Si),Zinc Selenide(ZnSe). The high precision parallelism of 10 arc seconds, surface quality of 10/5 and flatness of λ/20.Single layer or multi-layer anti-reflection coatings are available.
