The increased optical output power allows for greater measurement accuracy and faster processing of biological samples. 488-nanometer laser diodes are essential for modern diagnostics and research, powering applications such as blood, serum, and plasma analysis, as well as flow cytometry and DNA sequencing. This method for diagnosing genetic diseases involves directing light through a biological sample. Nucleotides, the building blocks of DNA, absorb and emit light differently, allowing their sequence to be determined precisely. A more powerful laser diode enables faster and more accurate analytical results.
“Our 488-nanometer laser diode offers exceptional optical performance, ensuring reliable analysis and reducing power consumption. It is therefore the perfect choice for applications where precision is paramount, whether in laboratories, hospital settings, or forensic facilities. This diode stands out for its low noise level, wide modulation bandwidth, and excellent beam quality,” emphasizes Winfried Schwedler, Marketing Director at ams OSRAM.
Cyan light is highly effective at stimulating fluorescent dyes used in diagnostic devices, such as flow cytometers and blood analysis equipment. Designed for precise wavelength control of ±2 nanometers and a high light intensity of 300 milliwatts, this diode is ideal for life science applications requiring exceptional visibility and high accuracy. Its wide modulation bandwidth allows for precise control of light intensity, significantly improving both signal quality and the speed of analytical processes.
This new diode from ams OSRAM also impresses with its low thermal resistance, ensuring reliable operation even at high temperatures. An integrated photodiode for output control and an ESD protection diode further enhance the robustness and reliability of the cyan laser diode.
While ideal for life science research, the cyan laser diode offers remarkably versatile potential for a wide range of other applications. By expanding the color gamut in stage and stadium lighting, for example, it creates vibrant and eye-catching visual effects. In the field of fluorescence microscopy, the specific wavelength of 488 nanometers provides enhanced visibility, allowing for clearer visualization of fine details that can be difficult to detect with conventional light sources.
