Multi-Line CW Single-Mode Laser | SIMTRUM Photonics Store

Our Multi-Line CW Single-Mode Laser(The four-in-one laser) includes four different wavelengths  (405nm/488nm/532nm/640nm or 405nm/488nm/561nm/640nm), integrating laser diodes, laser cavities, fiber-coupled optics, laser power supply and LD current into one unit. It is designed for laser scanning confocal microscopy system.

The four-in-one laser in a laser scanning confocal microscopy system is a special laser system used for biomedical research and clinical applications. It combines four different wavelengths of lasers to provide multiple excitation light sources. Laser scanning confocal microscopy is a high-resolution microscopy technique that acquires the three-dimensional images of cells and tissue through laser beam scanning and focusing. The four-in-one laser provides different wavelengths of lasers for the laser scanning confocal microscopy system to excite different fluorescent dyes or markers, allowing for observation and study of samples under a microscope.

Different wavelengths of lasers can interact with different fluorescent dyes or markers, allowing for visualization and localization of different cellular and molecular structures. For example, 405nm laser is typically used for exciting ultraviolet dyes, 488nm for  fluorescein and green fluorescent protein, 561nm laser for yellow fluorescent protein and red fluorescent dyes, and 640nm laser for fluorescent protein and infrared dyes.

The advantage of the four-in-one laser system lies in its ability to provide multiple wavelengths of laser light sources, enabling simultaneous excitation of multiple fluorescent dyes or markers, obtaining more comprehensive information in a single experiment. This is of great significance for multi-color fluorescence imaging, co-localization, and co-expression studies of cells and tissues.
