Borosilicate crown glass
Crown glass is a type of optical glass used in lenses and other optical components. It has relatively low refractive index (≈1.52) and low dispersion (with Abbe numbers around 60). Crown glass is produced from alkali-lime silicates containing approximately 10% potassium oxide and is one of the earliest low dispersion glasses. WebJul 18, 2024 · They reflect according to the reflective index and their wavelength. The greater the wavelength the faster they will travel. Red color travels fastest in crown glass as it has the largest wavelength ( 625 – 740). Blue travels at a speed lower than red. Violet travels with the least speed or lowest speed from crown glass.

WebBorosilicate glass is a type of glass with the main glass-forming constituents’ silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion (∼5 × 10 −6 / °C at 20 °C) making them resistant to thermal shock more so than any other common glass. 6.3.3.2 Silicon carbide (SiC) WebA quick search reveals: K9 is a Chinese Optical Borosilicate Crown Glass. It has low inclusions and bubbles. It is used for lenses and prisms for lasers and optics. It has good physical properties and can be polished like leaded glass. It also weighs approximately 15% less than full (24%) leaded glass (crystal). A US equivalent is BK7. 5 1
