What are the applications of balls?
Optical experiments: for focusing, collimating and shaping of light beams to support various optical studies.
Laser processing: for laser cutting, welding and marking to improve processing precision and efficiency.
Medical equipment: for endoscopy and laser therapy to improve imaging quality and treatment effects.
Comparison of fused silica balls and BK7 balls
1. Material Characteristics
Fused silica (SiO) has high UV transmittance, low thermal expansion coefficient, high-temperature resistance and good chemical stability.
BK7 is borosilicate glass with high visible light transmittance, easy to process, low UV transmittance and high coefficient of thermal expansion.
2. Optical Performance
Fused Silica Balls
Transmittance: high transmittance from UV to NIR wavelengths
Refractive index: approx.1.46 (@587.6 nm)
Chromatic dispersion: low dispersion
BK7 Balls
Transmittance: high transmittance mainly in the VIS to NIR wavelengths
Refractive index: approx.1.52 (@587.6 nm)
Chromatic dispersion: high dispersion
3. Application Scenarios
Fused silica ball applications: ultraviolet optical systems, laser systems, high-temperature environments, chemical corrosive environments
BK7 ball applications: visible optical systems, microscopes, camera lenses, general optical experiments
4. Cost
Fused silica balls cost more than the BK7 balls
What are the advantages of sapphire balls?
Sapphire balls are ideal for optical applications in extreme environments due to their exceptional hardness, wear resistance and chemical stability. Sapphire is a hard material that effectively resists scratches and abrasion, while providing excellent thermal stability and corrosion resistance for high temperatures, high pressures and highly corrosive environments.
Sapphire balls exhibit excellent optical transmittance in the ultraviolet (UV), visible (VIS), and infrared (IR) wavelength bands (transmission range: 0.15μm-5.5μm), enabling them to meet a wide range of spectral applications. Its spherical design not only provides uniform optical performance, but also enables efficient light focusing and beam control.
