Definition and application of optical lenses

Optical lenses are widely used in a variety of optical, experimental instruments, imaging, security monitoring, laser, industrial vision systems, aerospace, detection equipment and more fields. It mainly plays the role of changing optical system light path according to specific needs. Optical lenses with specific parameters can be designed using suitable materials to meet different applications. In addition, these lenses can be coated with various optical coatings to enhance their optical performance.

Types of optical lenses

Generally, optical lenses have Plano-Convex Lens, Bi-Convex Lens, Plano-Concave Lens, Bi-Concave Lens, Meniscus Lens, Cylindrical Lens, Achromatic, Ball & Half-ball Lens, Aspherical Lens and other types. These optial lenses are made by cutting, grinding and polishing processes. After strict process control, they can be given a very good surface quality, precise surface accuracy and the centrality.

Creator Optics (CNCO) manufactures a wide range of optical lenses made of optical glass, optical crystals, and laser crystals. The main materials include BK7 glass and all catalog optical glass, Fused Silica, Sapphire crystal, Quartz crystal, Germanium (Ge) monocrystal, Silicon monocrystal, ZnSe, Barium Fluoride (BaF2), Calcium Fluoride (CaF2),ZnS, Pyrex, BOROFLOAT, float glass, etc.

Optical lenses made of specific materials, coated with corresponding optical films, are applied in different wavelength bands from ultraviolet and visible to infrared.

Some important parameters to consider when selecting optical lenses:

  • Dimensions of optical lens: Conditions for lens installation in optical systems.
  • Lens type: The role of this lens in the system.
  • Materials: A method of selecting the appropriate material in the application band. It is necessary to comprehensively consider the application wavelength, refractive index, processability, physical properties, economy and other factors of the material.
  • Surface Quality: 80/50, 60/40, 40/20, 20/10, 10/5 according to MIL-O-13830A. The smaller the value, the higher the accuracy, and the less defects on the surface and materials.
  • Surface Accuracy: It is usually identified by a Newtonian ring. N/ΔN regular/irregular 3/1, 1/0.5, etc. The smaller the surface accuracy value, the closer the surface of the lens is to the design curvature. This is an important factor affecting the imaging characteristics of the optical lens.
  • Coating: The design band of the optical system and the use band. Specific single or multi-layer anti-reflective (AR) coatings are required to meet different requirements. Customized optical coating.
