The SP-20 is a light guide coupled, tunable and single pulsed flash lamp system featuring a high pulse energy and quartz optics. Compared to the JML-C2, the system offers a pulse length from 4 to 300 µs at the full width half maximum (FWHM) depending on the settings. Thus, the SP-20 is the perfect flash lamp solution for all applications where a microsecond light pulse with high energy is required.
The SP-20 flash lamp system can be adapted to almost all models of major research microscope brands. In general, two kinds of illumination are possible based on the light guide and the type of adaptation. Coupling by a liquid light guide adapter (LGA) gives the possibility to illuminate the whole field of view. In contrast, a spot illumination module (AiWon) enables the user to illuminat a quite small area of the field of view with a high energy light pulse.
Easy Control and Adjustment
This pulsed light source system can be triggered externally by an optical isolated trigger signal to avoid any disturbance of the light flash. The energy level is adjustable via the capacitor settings. To define a specific spectral output based on your experimental needs, up to two optical filters can be placed between the bulb and the light guide.
- Flash Uncaging
- Flash Photolysis
