Blue lasers excel where traditional IR lasers struggle, particularly with reflective or heat-sensitive materials, for example, engraving on metals (copper, gold, silver, aluminum), plastics & polymers, and ceramics & glass; and cutting on thin metals and delicate Materials.
However, beam shaping of blue lasers presents certain challenges compared to infrared light:
- Common optical materials tend to absorb blue light more than infrared light. For example, high-refractive-index glasses like S-TIH53, often used for infrared, show higher absorption in the blue spectrum.
- Laser absorption by materials can lead to thermal lensing effects, causing dimensional changes in optical components and impacting optical performance.
- Temperature rise in micro-optical lenses can affect adhesive performance, further influencing overall optical quality.
Focuslight addresses these challenges through optimization in material selection, optical design, surface shaping, coating, and quality control to enable efficient beam shaping for blue lasers. We offer a wide range of standard micro-optical products suitable for blue diode lasers, supported by scalable mass production capabilities. With over 30 years of experience in customized optical solutions, we provide a one-stop service from design and manufacturing to assembly and testing.
