NEWTON, N.J., June 20, 2013 — Thorlabs has released the PM160, an all-in-one wireless power meter with a built-in sensor. The instrument has an OLED screen for local operation as well as Bluetooth wireless technology and a USB port for remote control with a PC. The battery provides up to 20 h of continuous operation while in the Bluetooth mode and is rechargeable via USB. Designed to detect light in the 400- to 1100-nm range, the 9.5-mm ultraslim silicon sensor can measure optical powers between 10 nW and 20 mW. A neutral-density filter slides along the sensor arm and snaps into place, increasing the maximum measurable power to 200 mW. Each meter is shipped with a unit-specific calibration certificate. Designed for handheld use, the device has three taps for post mounting in a variety of configurations. The arm containing the sensor is 3.5 mm thick (6 mm with the filter) and can rotate up to 270°, making it suitable for tight spaces. An adapter enables integration into fiber optic systems. When controlled locally through the OLED screen menus, the meter can be zeroed, programmed to display the average power of an incident beam, or set to output the maximum power reading over a user-specified period.
