Optical Lenses are optical additives designed to cognizance or diverge mild. Optical Lenses, which may additionally encompass a unmarried or a couple of factors, are utilized in a huge form of programs from microscopy to laser processing. Many industries utilize Optical Lenses, such as existence sciences, imaging, commercial, or protection. As light passes thru a lens, it's far stricken by the lens’ profile or substrate. A Plano-Convex (PCX) or Double-Convex (DCX) lens reasons mild to cognizance to some extent, while a Plano-Concave (PCV) or Double-Concave (DCV) lens causes the light travelling thru the lens to diverge. Achromatic Lenses are perfect for programs requiring colour correction, while Aspheric Lenses are designed to accurate round aberration. Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) lenses are ideal for transmitting the Infrared (IR) spectrum, even as Fused Silica is properly suited for the Ultraviolet (UV).
These lenses may be used to increase the numerical aperture of a positive lens assembly, without an undue increase in the aberrations.
Negative lens with the form most suited to producing diverging light or a virtual image, where the input light is converging.
Most suitable where the conjugates are on opposite sides of the lenses and the ratio of the distances is less than 5:1, e.g. as simple image relay components.
Negative lens with the form most suitable where one conjugates is more than five times the other, e.g. producing divergent light from a collimated input beam.
Positive focus length. Most suitable where one conjugate is more than five times the other, e.g. in sensor application or for use with near collimated light.
