Notes :
1. 10.6µm is the predominant wavelength. This can typically vary in the range 10.45µm–10.7µm
2. Minimum and maximum optical modulation depths are frequency and duty cycle dependent – minimum depth occurs at short pulse widths and high frequency. For the SCX 35 the following optical modulation depths are typical: a.10kHz–44 to 100%, b.30kHz – 17 to 100%, c.60kHz – 11 to 71%
3. The pointing stability stated is based upon the full range of available pulse widths. At a fixed pulse width stability will be significantly better
4. Mean average power at maximum duty cycle
5. When supplied with power feedback assembly. (Turn on response is typically 300 to 500 milliseconds)
6. Minimum power with power feedback is 25W
7. Quoted from 10-90% level |
