Description
638 nm is one of the key wavelengths in fluorescence imaging and flow cytometry. Laser diode-based model emits red radiation with high wavelength and power stability and up to 10 MHz modulation frequency. A 200 mW laser diode at 638 nm is used in this module and we leave some headroom for an extended lifetime. Slight wavelength tunability is also possible with an inbuilt Peltier element.
By default, this
type of laser is built with FC/PC connector, but other fiber
terminations are available upon request. Details about non-standard
connector and the fiber used with it should be discussed with the
Integrated Optics sales team.
Fiber Termination - FC/PC (PT):
FC/PC has good insertion repeatability, therefore is often used in single-mode fiber applications. Features a key for polarization-maintaining fiber installations.
