1. K9 Optical Glass (Economy & Industrial Grade)

Performance: A versatile borosilicate crown glass offering excellent transmission from 380nm to 2500nm.

Key Features: Highly cost-effective and readily available for bulk production.

Best For: General industrial optics where high-end scientific precision is not required.

Recommended Applications: Laser Marking and Engraving.

2. N-BK7 Optical Glass (Precision & Scientific Grade)

Performance: Shares the same refractive index (1.517) as K9 but with superior internal homogeneity and lower inclusion counts.

Key Features: Engineered for tighter tolerances and a premium surface finish to minimize wave-front distortion.

Best For: High-accuracy scientific instruments and advanced optical systems.

Recommended Applications: Metrology, R&D, and Laboratory Research.

3. Fused Silica / Quartz (High-Power & UV Grade)

Performance: Features a lower refractive index (1.458) and a significantly wider transmission range from 185nm to 2500nm (Deep UV to NIR).

Key Features: Exceptional thermal stability and the highest laser damage threshold available.

Best For: Environments subject to high heat or high-intensity laser energy.

Recommended Applications: High-Power Laser Cutting and Industrial Welding.
