Yiqihighgo 25 x 25 x 1mm Optical Glasses(5 Pcs),High Borosilicate Glasses

• Premium Material - Our optical glasses are made from high borosilicate glass. Size : Length 25mm, width 25mm, thickness 1mm.Package : 5 pcs optical borosilicate glasses.We prioritize the safety of our products during shipping.Each borosilicate Glass set is carefully packaged in a plastic box.Our borosilicate glass set is carefully packaged in thickened packaging to prevent breakage.
• Safety and Optics - Large cracks are generated during crushing instead of crushing particles, with high light transmittance (about 92% with a thickness of 2 millimeters), making it safer and clearer to use. Meanwhile, high borosilicate glass also has low dispersion and relatively low refractive index.
• Versatile and Multipurpose - These double-side polished borosilicate glass sheets are suitable for various research laboratories and industrial applications.
• Thermal performance - The coefficient of thermal expansion is extremely low, only one-third of that of ordinary glass, and can withstand instantaneous temperature differences of 150-200 ℃, with a softening point of about 820 ℃. Resistant to high temperatures ranging from 1200 ℃ to 1500 ℃, with good thermal stability.
• Chemical stability - Excellent water and acid resistance, except for hydrofluoric acid and high-temperature concentrated phosphoric acid, it can withstand most acid-base and organic solvent corrosion.
