All technical data are valid at 23 ± 5°C and 45 ± 15% rel. humidity.
1)
The wavelength range of the supplied UV ND filters starts at 200 nm, see chapters Filter Wheel
2)
@ 400 nm depending on beam diameter and ND filter.
3)
The neutral density filter will begin to heat up and can be damaged if exposed to incident powers above 1 W for
more than a few seconds.
4)
@ 700 nm depending on beam diameter and ND filter.
5)
Damage threshold data is currently not available for the BC207 beam profilers. For applications with pulsed
lasers, we recommend the following procedure as a guideline for determining a safe upper limit: Set the beam
profiler to the maximum integration time (i.e., set the exposure to 1 s). Slowly increase the power until your signal
reaches approximately 50% of the intensity as shown in the profile window of the Beam Software package. Mul-
tiply this power by a factor of 10. This is the safe upper limit of the mean pulse power for the beam profiler.
6)
These filters are provided for use near the 400 nm upper wavelength range of the BC207UV(/M). See the chapter
Filter Wheel for more information.
7)
One set of filters is AR coated for the 350 nm to 700 nm range while the other is AR coated for the 650 nm to the
1050 nm range. See the chapter Filter Wheel for more information.
8)
Highly dependent on PC processor, graphic adapter performance, and size of calculation area.
9)
In Multi Pulse Detection, single pulses are not distinguished.
10)
See chapter Trigger Input for detailed data.
