The table below illustrates the basic matrix of focusing schlieren systems and their ranges of utility. Lower frame rates (FPS) and longer shutters correspond to more economical systems, since they require slower cameras and less light.
Digital Focusing Schlieren * ≤ 3 ft./1 m diameter * more economical |
Analog Projection Focusing Schlieren * larger areas * (usually) higher sensitivity |

---|---|---|
Video Rate (shutter > 1 ms, 100 > FPS) | sTube™ with consumer-grade digital display | Schlierenscope |
Short-Exposure Video Rate (shutter ≥ 1µs, 100 > FPS) | sTube™ with our FlashScreen display | High-Speed Schlierenscope |
High-Speed Short-Exposure Video (shutter ≥ 1µs, 100 < FPS | sTube™ with our PowerBox display | Custom development (contact sales@spectabit.com) |
Note: shutter speed and FPS (frames per second) ranges are approximate and may vary somewhat depending on particular hardware specifications.
