Spherical lenses
Spherical lenses (diameter from 2 to 300 mm) made from optical glass, quartz, crystals (Ge, Si, ZnSe, ZnS). Domes made of glass and crystals
AtlantOptics manufactures spherical lenses of various shapes from glass, quartz and crystals with subsequent application of optical coatings.
-Diameter of commercially available spherical lenses from 2mm to 250mm.
Types of lenses:
1. Flat-convex lens: This lens has one convex surface and one flat surface. It collects light and focuses it to a given point behind the lens.
2. Flat-concave lens: This lens has one concave surface and one flat surface. It scatters the light making it diverge and creates a negative focal length.
3. Double-convex lens: This lens has two convex surfaces and collects light by focusing it at an intermediate point between the lens and the object.
4. Double concave lens: this lens has two concave surfaces and it scatters the light making it divergent. It has a positive focal length and focuses the light after the lens.
5. Meniscus lens: This lens has one surface that is concave and another that is slightly convex. This lens shape allows light to be focused and also corrects some aberrations such as chromatic aberration, such as in collimators where the meniscus minimizes the focal spot.
Glass and crystal domes.
We produce polished domes (hemispheres and hyperspheres). Depending on the operating spectrum of the system, the domes are made of quartz glass (QG) or sapphire for UV, visible and near IR and zinc selenide (ZnSe) for mid-wave and far IR.
We make domes (hemispheres, hyperspheres) from crystals and glass: CVD-ZnSe (zinc selenide), CVD-ZnS (zinc sulfide), sapphire (leucosapphire), Si (silicon), Ge (germanium), CaF2 (calcium fluoride, calcium fluoride), BaF2 (barium fluoride, barium fluoride), MgF2 (magnesium fluoride, magnesium fluoride), LiF (lithium fluoride, lithium fluoride), glass and quartz glass
