Newport’s laser power alignment kits are an ideal tool for aligning various types of lasers. The kits include an 1917-R laser power meter and a broad choice of photodiode and thermopile detectors. The kits also include the mounting accessories as well, thus simplifying product selection and ordering. One can simply purchase an additional power meter or a detector as different and more complex measurement requirements arise.
The LAKIT-THERM-30W is the recommended replacement for the obsolete 407A series power meters.
The types of detectors available in the kits are: 918D Series detectors for low power (< 2 Watt) cw lasers in the visible or in the IR, and 818P thermopile detectors. The 918D Series photodiode detectors are equipped with an integrated OD3 attenuator, increasing the measurement dynamic range. For power density ranges below 1 mW, we recommend to set the attenuator to the OFF position for the best signal to noise ratio. The 818P Series thermopile detectors are a great choice for measuring the average power for high power lasers operating both in cw or pulsed mode over a broad wavelength range between 0.19 to 10.6 µm. Fiber adapters are separately available for purchase for both the photodiode and the thermopile detectors.
