In the world today, we take for granted a wide variety of ways to use light. Industry uses camera systems for photo recognition and thermography, and laser systems are increasingly important in medical technology, analytic measurement technology and materials processing. The steady trend is toward higher resolution in camera systems and higher performance in laser systems. More complex applications mean more stringent requirements for optical systems. Heraeus manufactures laser excitation lamps, quartz glass blanks and prism materials for the components of these optical systems—not only in standard materials and sizes, but often as custom-tailored solutions. Very large dimensions (up to 1 meter in diameter), outstanding optical homogeneity and high radiation resistance for high-performance lasers or space technology are just three of many aspects that our customers value.
