* : All values are for an entire family and not a specific product.  See the specification sheets for the values of individual detectors.
⁽¹⁾ : From Noise Equivalent Energy (NEE) to maximum measurable energy with QED attenuator (when applicable).
⁽²⁾ : On special request only.  Standard pulse widths are 10 µs, 150 µs and 400 µs.
⁽³⁾ : On special request only.  Standard pulse widths are 10 µs, 225 µs and 675 µs.
⁽⁴⁾ : This value is dependant of the maximum pulse width chosen and can be lower than specified in this table.
⁽⁵⁾ : With QED attenuator when applicable.
