The 919E-30-46-10K pyroelectric energy detector comes with a removable diffuser based attenuator for high energy YAG and erbium lasers. It has a 46 mm aperture with diffuser out and 33mm aperture with diffuser in. It can measure energies from 10 µJ up to 30 J. It can operate at repetition rates up to 10 kHz and is calibrated specifically for 1.064 (both with diffuser in and out), 0.532 (with diffuse out only), 2.1 and 2.94 µm (with diffuser in only). The sensor comes with a standard 1.5 meter cable for connecting to a power meter. Compatible power meter models include 1919-R, 843-R, 843-R-USB, and 841-PE-USB. Since certain specifications are interrelated with various settings, please refer to the complete specifications sheet under Resources below to determine if this product meets your requirement. Cable length is 1.5 meters. It has one 1/4-20 tapped hole on the side and one M6 hole on the back side of the head for mounting and comes with a 1/2 inch diameter post.
