400 nm Violet Laser Narrow Linewidth Linewidth <0.03 nm MDL-E Series Diode Lasers
MDL-E series lasers, with the characteristic of ultra narrow spectral linewidth< 0.03nm, are ideal for application in DNA sequencing, flow cytometry, digital imaging, analytical chemistry, particle measurement, confocal microscopy, Raman spectroscopy and many other fields. Housed in ultra compact package, these lasers are the good choice for OEM instrumentation, systems design and integration, and also for end user applications in research and development.
