DESCRIPTION

DESCRIPTION
x

This product is manufactured from genuine BF33 high borosilicate glass, a premium float glass material widely recognized for its excellent thermal stability, high optical clarity, and superior chemical resistance. Due to its low thermal expansion and strong resistance to temperature changes, BF33 glass is commonly used in demanding optical and laboratory environments.

Each glass plate is precision cut and carefully processed to ensure accurate dimensions, smooth surfaces, and clean edges. The naturally smooth float glass surface provides reliable optical quality and is suitable for further processes such as coating, bonding, or optical assembly.

With its combination of low thermal expansion, high visible light transmission, and excellent chemical durability, BF33 borosilicate glass is widely used in optical systems, semiconductor equipment, laboratory instruments, and industrial applications where thermal stability is critical.
