1. Manufacturing Process

The production of the Borosilicate Window Dia. 5 mm x Thk. 1.75 mm, Uncoated involves a specialised melting and shaping procedure that ensures optimum clarity and precision. Skilled technicians monitor the temperature of the borosilicate glass rods as they are heated to their ideal working point, forming the initial shape and diameter. Advanced moulding methods are then employed to achieve the exact thickness needed, ensuring consistency across multiple units. This meticulous process yields windows with exceptionally stable dimensions and a uniform, uncoated surface.

Highly controlled cooling protocols are critical to minimise internal stress and preserve structural integrity. Each piece undergoes a carefully timed annealing cycle, helping the glass adapt to room temperature without developing microfractures. Sophisticated quality checks at every stage verify that the finished windows retain minimal distortion and satisfactory surface uniformity. The end result is a highly durable and dimensionally accurate borosilicate window suitable for precise analytical and optical applications.
