 ATOPTIK - Professional Optical Material Manufacturer

Materials for optics ‌refers to the general term of materials with certain optical properties and functions used in optical experiments and optical instruments. These optical materials play a key role in optical systems, being able to transmit, alter or control the propagation of light. The main types of optical coatings include optical glass, optical crystal and so on. ATOPTIK provides high-quality optical lens material to meet diverse needs in imaging, lasers, and more.

 

The main properties of optical materials

Optical Performance: Refractive index controls light bending; materials like high-index glass provide precision optics. Dispersion varies (flint glass has high dispersion, crown glass low). Transparency across wavelengths is vital (e.g., UV-grade fused silica for UV, N-BK7 for visible light).

 

Physicochemical Properties: Homogeneity ensures consistent refractive indices. Chemical stability (e.g., phosphate glass resists acids) and hardness (e.g., alumina, Mohs 9) improve durability.

 

Thermal Behavior: Low thermal expansion (e.g., alumina) ensures stability in high temperatures. Thermal shock resistance is crucial for aerospace sensors.

 

Processability & Cost: Machinability varies; engineering plastics are easy to mold but heat-sensitive, while synthetic crystals allow tailored growth. Sputtering efficiency affects costs.

 

Functional Traits: Birefringence in non-cubic crystals supports polarization. High-purity alumina is ideal for 5G RF devices.

Plano Convex Lens

Image
  ATOPTIK can process ultra-high precision optical plano convex lens  with ultimate surface accuracy up to λ/20 and a maximum diameter of Ø150mm.   Overview of plano convex laser lenses A plano convex spherical lenses  consists of one flat surface and one convex surface, with a positive focal length. It can focus parallel light rays into a point or transform a point light source into a collimated beam. When in use, it is generally recommended to orient the convex surface toward the incident light to minimize spherical aberration.   Applications of Plano Convex Lens 1. Optical Focusing and Collimation Plano-convex lenses are widely used in laser systems for focusing high-energy beams, such as in laser cutting and welding, or for collimating divergent light sources. Their positive focal length and ability to reduce spherical aberration make them ideal for applications where precise beam shaping and minimal distortion are essential.   In imaging devices like m...

Optical Mirrors

Image
  An optical mirror   is an optical element that reflects light.   It is composed of one or more reflecting surfaces, such as spherical, flat or aspherical surfaces. Reflecting the required spectrum according to the design requirements, laser mirrors for sale   is widely used in astronomy, physics, optics, laser processing, medicine, industry and other fields.   Types of optical mirrors for sale Scanning Mirror Galvanometers, also known as galvanometric scanners, are specialized oscillating motors that differ from conventional rotary motors.   Optical Metal Mirror Mirrors are optical components that operate based on the law of reflection, primarily used for beam redirection, interferometry, imaging, or illumination.   Dielectric Mirrors Dielectric mirrors can achieve extremely high reflectivity (exceeding 99.8% in the designed wavelength range), primarily used to minimize losses when reflecting laser beams and other light sources.   Comparing opti...
