| Interface |
High-speed USB 2.0 connection |
| Power supply |
Power consumption <2.3 W, supply directly via USB cable |
| (1) With multi mode fiber |
|
(2) Only for standard range of 370-1100nm |
|
(3) But not better than 5% of the linewidth |
| (4) According to 3σ criteria |
|
(5) Without auto-calibration usage |
|
(6) The cw power interpretation in [µW] compares to an exposure of 1s (generally the energy needs to be divided by the exposure time to obtain the required power) |
