Review on METBENCH by Doug Booth

It is simple to use, has high accuracy and can be used with all laser types in the visible range. The software interface could have been more user friendly. It should also provide optionality of the measurement frequency, since it takes sometimes long time to measure certain levels of laser light. I would recommend this product if you are looking for an excellent linearity test system. We are using it to guarantee that our laser sources are operating at their best performance or to determine when changes in the laser source will affect the system operation. I like that it is easy to use, it has an automatic calibration feature, and it is very precise. The unit can be somewhat expensive, but if you are going to purchase this there is little reason not to go ahead with it. There is nothing I dislike about this product. I am using this to calibrate various optical power meters. It works well, and provides reliable results.
