(a) All technical data are valid at 23 ± 5°C and 45 ± 15% relative humidity (non-condensing).

(b) Values for transimpedance and conversion gain are lossless gain values [i.e. losses introduced by the FC/APC connectors (typically 0.15 to 0.35 dB) are not considered].

(c) For a 50 Ω load.

(d) For more information on NEP, please see Thorlabs' Noise Equivalent Power White Paper.

(e) A replacement power supply is available below.
