Custom High precision optical ball lens for laser focusing systems

1. ‌Material‌

• ‌Glass‌:

  • High-grade optical glass is commonly used due to its excellent optical properties, such as low dispersion and high transmittance.
  • Types include fused silica, BK7, and other specialty glasses tailored for specific wavelength ranges.

• ‌Crystal‌:

  • Some applications may require the use of crystalline materials like sapphire or spinel for their exceptional hardness, chemical resistance, and optical clarity.

2. ‌Property‌

• ‌High Precision‌:

  • Manufactured to tight tolerances, ensuring accurate focal length, numerical aperture, and wavefront distortion specifications.

• ‌Surface Quality‌:

  • Ultra-smooth surfaces with minimal scratches, digs, and inclusions to maintain high transmittance and reduce scattering.

• ‌Thermal Stability‌:

  • Designed to minimize thermal expansion and refractive index changes over a specified temperature range.

• ‌Durability‌:

  • Resistant to environmental factors such as humidity, chemicals, and mechanical stress.

3. ‌Function‌

• ‌Focusing‌:

  • The primary role of the ball lens is to focus a laser beam to a tight spot, enhancing intensity and enabling precise cutting, drilling, or marking operations.

• ‌Collimation‌:

  • In some configurations, it can also collimate divergent laser beams into parallel rays, essential for applications requiring a uniform beam profile over distance.

• ‌Beam Shaping‌:

  • Custom designs can alter the beam shape or intensity distribution to match specific application requirements.

4. ‌Application‌

• ‌Laser Cutting and Engraving‌:

  • Used in industrial laser systems for precision cutting and engraving of materials ranging from metals to plastics.

• ‌Medical Devices‌:

  • Integral in laser-based surgical tools for procedures requiring high precision and minimal tissue damage.

• ‌Optical Communications‌:

  • Employed in fiber optic couplers and isolators to ensure efficient transmission of light signals.

• ‌Scientific Research‌:

  • Critical in experimental setups for laser trapping, imaging, and spectroscopy due to their ability to produce highly focused beams.
