We often are asked about measuring the power of widely diverging beams and how to do so.

First of all, Ophir has integrating sphere power meters designed for divergent beams of up to +/-40 degrees divergence. These are the 3A-IS and 3A-IS-IRG power meters. These power meters are primarily for low power beams of under 3W and for the spectral regions 420 – 1100nm and 800 – 1700nm. Read the full article

A few months ago we posted a blog with several examples of cases where beam profilers helped manufactures and companies. Here are a few examples where a beam profiler was used to indicate and repair lasers that malfunctioned in the medical industry.   Read the full article

A few months ago we posted about Ophir 3A series of thermal sensors which can measure powers as low as 60 microwatts. The only technology that can be used to measure powers which are lower than a few microwatts is photodiode sensors. Photodiodes are sensitive to extremely low power levels, as low as picowatts.

We have done a lot of innovating in our product lines recently, and while it certainly further strengthens our position way ahead, it also creates a need to keep everyone updated. The goal of this Webinar is to bring you, our customers – many of whom have been with us for a long time – up to date and onto the same page. It will help you get educated about the latest innovations at Ophir and learn how those innovations can help you. Read the full article

The biggest issue is picking out the appropriate sensor that will measure the laser light (most will measure other types of broadband light as well). Since it is not trivial to find the best sensor for a given application, we recommend using our Sensor Finder available on our website that automatically calculates the best sensor for the measurement conditions you input.

However, let us list below the main criteria: Read the full article
