New Laser Filter For UV Lasers

Almost all lasers need attenuation before pointing them at a camera for profiling because otherwise they are too strong. One either needs a beam splitter or a filter. The splitter, though a fine solution, allows for less adjustment than a filter. Until now there were only beam splitters for UV lasers but now Ophir-Spiricon has released special filters, the Neutral Density Laser Beam Filters for UV Wavelengths (UV-ND Filters).

The filters that existed before this new one are made of glass so they don’t work with UV-wavelength. On the other hand, the Ophir-Spiricon UV-ND filters use fused silica which can transmit at much shorter wavelengths (190-380nm).

To learn more about these new filters for UV lasers and the technology used to ensure smooth and accurate transmission through the filters to the beam profiler camera, read Ophir Optronics Announces New Neutral Density Laser Beam Filters for UV Wavelengths.

Beam profiling in a nutshell

Take a look at these images:

You don’t have to be an expert to see that the six-month profile is less efficient than the factory one. These images show the natural degradation of a laser. It is through beam profiling that one would be aware that there are changes and know exactly what changes are happening.

BeamGage: The Next Generation of Laser Beam Analysis Software.

2010-7-8 – beamgage

The latest software released by Ophir-Spiricon is BeamGagewhich is the first software that analyzes both laser power/energy (Ophir’s expertise) and beam profiling (Spiricon’s expertise) simultaneously. BeamGage which can be used with any PC with Windows XP and beyond at a 32-bit mode, uses time stamps on both the laser power meter readings and the beam profile data, in order to attain a more complete understanding of your laser’s performance.

Smaller Is Better – A New Line of Thermal Laser Power Sensors.

An array of pins cool the device and keep its size down to around half of other comparable sensors on the market.The new line of Ophir thermal laser power sensors is out! These sensors are very compact because of their cooling systems.“These thermal laser power sensors are produced with a new manufacturing process that allows the devices’ disks to stand up to higher temperatures,” stated Ephraim Greenfield, CTO, Laser Measurement Group, Ophir-Spiricon. “This means they are more reliable under continued use and when cycling at high powers. And because of their superior cooling capacity, the devices are half the volume of competitive productsfor the same maximum power levels.”

Choosing The Right Laser Power Or Energy Sensor Is Easier Said Than Done.

Choosing the best laser sensor for a particular application can be quite overwhelming. To help make the process much easier, there is now a new tool that will direct you towards the laser sensors that will best fit your needs. It is the (free to use) Ophir-Spiricon Sensors Finding Program (SFP). We’ll talk more about it later (it definitely deserves its own blog post) but here’s the thing: When using the SFP, you’ll be inserting quite a few facts about your laser into the program and in order to insert them correctly, well, you’ll need to know what they are.We’ve created a short guidethat explains which details you need to know about your laser and why. Please keep in mind that it is of utmost importance to attain all of this information so that the sensor you choose will not get damaged and will give accurate readings. Just to give you an idea, here is a quick overview:

  1. Wavelength – The laser wavelength must be within the range of the sensor’s wavelength.
  2. Beam diameter – When you input the beam diameter, the Sensor Finder automatically takes into account that the sensor aperture has to be larger than the beam itself.
  3. Continuous wave (CW) or pulsed – Is your laser continuous or pulsed? Each type comes with different factors to consider like the range of average power or energy, pulse rate and width etc.
  4. Type of measurement required – There are three types of measurements: average power, energy or single shot energy. Basically, a continuous wave laser will need an average power measurement while a pulsed laser will most probably need an energy measurement because it provides more details about the pulses which is usually important. As for the single shot energy measurement, most sensors can provide this information.

How to Know If My Camera-Based Laser Beam Profiler Is Accurate?

Customers ask us how they can know if their laser beam profiler is accurate. This is an excellent and important question but unfortunately, there is no simple answer. The fact is that there is no calibration available for laser beam profilers. The next best thing is to use top quality pieces and technology so that we can conclude beyond a reasonable doubt that the profiling is indeed accurate.The article “A discussion of laser beam profiling and the subject of accuracy” goes in depth explaining what in the Ophir-Spiricon analyzers leads to high accuracy. Two of the main factors that create accuracy in our products are the following:
