    φακός γυαλιού 43mm οπτικός για την υποβρύχια φωτογραφία, φακοί σφαιρών 1,5 300mm μισοί

    43mm Optical lenses protective dome ball and half ball lenses glass cover used for underwater photography Concave lenses, are a simple lens with one spherical face and one flat plano face. Because the spherical face is concave the lens has a negative focal length, allowing the part to increase the divergence of convergent light. Concave lenses can be used to balance out the spherical aberrations caused by other lenses. This makes concave lenses very useful for controlling

    Optical BK7 Glass Hemisphere Optical Glass Half Dome Lens with 1mm Thickness A dome is composed of two parallel optical surfaces. Among optics domes are unique because, unlike any other optical components, the key attribute of the dome is to have no optical effect. Mirrors reflect light, lenses bend light, domes ideally change nothing. A dome is often exposed to the environment. Accordingly, domes made from hard ceramic materials are preferred due to their ability to
