A new “meterless”and ultra-slim laser power sensor from Coherent Inc. (Santa Clara, CA) is configured to enable measurements at points deep within instruments and between closely spaced components. This is possible because the PowerMax USB WandUV-VIS Sensor consists of a 10 mm diameter silicon detector mounted on the end of a 6" long wand that is only 0.2" thick at its end.
It is suitable for measuring the average power of lasers anywhere in the 325 nm to 900 nm spectral range, and can sense powers from 100 µW to 300 mW. As with Coherent’s other “meterless” products, all the meter electronics for the PowerMax USB Wand are contained within its own USB connector; the only additional equipment required to perform measurements is a PC equipped with Coherent’s Windows-based PowerMax software.
In addition to its convenient and flexible mechanical package, the PowerMax USB Wand also offers exceptional performance. In particular, it has been specifically designed to overcome the drift problems often experienced with silicon detectors operating in the UV, and delivers high stability measurements throughout its entire spectral range, together with an absolute calibration uncertainty of only ±2%. Plus, Coherent’sPowerMax software offers powerful functionality, including easy wavelength calibration adjustment and a full range of statistical and data logging capabilities.
The PowerMax USB Wand will be particularly useful for service personnel, system assemblers and even end users for a wide range of laser based instruments, such as flow cytometers and MPE microscopes. The sensor’s capabilities are further extended with various optional accessories, including an adapter to which an FC connector terminated fiber can be attached, a barrel that automatically positions the sensor relative to the collimators used on Coherent’s CUBE series lasers, and a post mounting clamp.
Founded in 1966, Coherent, Inc. is a world leader in providing photonics based solutions to the commercial and scientific research markets, and is part of the Standard & Poor’s SmallCap 600 Index and the Russell 2000.
