ASKION LASER-line® Laser diode modules
The LASER-line® Laser diode modules differentiate to our standard Laser cw-Modules by the capability to modulate the light with short rise time and up to a speed of 100 kHz.
-
Typical applications are fluorescent- optical measurements like laser scanning microscopy and flowcytometry. Additional wavelengths are available on request.
-
LD modules are available fiber coupled or as free beam modules.
-
Selectable are wavelengths and different optical output power.
