(a) Wavelength range of supplied UV ND filters start at 200 nm.

(b) At 400 nm, depending on beam diameter and ND filter. See Manual for details.

(c) The neutral density filter will being to heat up and can be damaged if exposed to incident powers above 1 W for more than a few seconds.

(d) At 700 nm, depending on beam diameter and ND filter. See Manual for details.

(e) Damage threshold data is currently not available for our beam profilers. For use 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. Multiply this power by a factor of 10. This is the safe upper limit of the mean pulse power for the beam profiler.

(f) These filters are provided for use near the 400 nm upper wavelength range of the BC207UV(/M). See the manual for more information and coating curves.

(g) 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 1050 nm range. See the ND Filters tab for more information.

(h) Highly dependent on processor, graphic adapter performance, and size of calculation area.

(i) In Multi-Pulse Exposure, single pulses are not distinguished.

(j) See the manual for detailed trigger data.

All technical data are valid at 23 ± 5 °C and 45 ± 15% relative humidity.
