Precise measurements of pulsed laser energy can be accomplished with Newports 818J Series Energy Detectors, which utilize crystalline pyroelectrics. This detector is packaged in an EMI-shielded cylindrical housing that mounts directly to our English posts.

Calibrated measurements can be performed by ordering the /CM versions of these detectors for use with Newports 1835-C and 2835-C Optical Meters.

Large expanded beams can be accommodated with detector diameters of 25 and 50 mm. Black-organic coated 818J-25B and 818J-50B detectors are suitable for most applications. This coating flattens spectral response from UV to deep IR and eliminates beam retro-reflection, while providing more damage resistant operation, but repetition rates are limited to 50 and 100 pps respectively.

SPECIFICATIONS:
• Spectral Range : 0.19 m - 20.0 m
• Maximum Energy: 1.01 J (at 15 sec pulse width)
• Maximum Pulse Width: 400 s

Comes with 2 "damage test slides", cable with 2 BNC type connector and a Cal.Module
