Custom High precision optical ball lens for laser focusing systems
1. MaterialGlass: - 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. PropertyHigh 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. FunctionFocusing: - 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.
