Accessories

When performing beam profiling measurements on a laser, it is sometimes necessary to manipulate the beam in order to achieve a signal that is suitable to be measured. Occasionally, the beam needs to be sized correctly by either increasing it if it is too small, or increasing it if it is too large. Often times, the laser’s power needs to be reduced to a certain level to be imaged. These accessories are complementary products to our beam profiling imaging devices in order to achieve proper beam sizes and power levels so that you can achieve the most accurate measurements possible.

  • Neutral Density Filters

    Reduction of the laser power before reaching the camera is often times required to obtain a usable signal, one that is not saturating or damaging the camera. These filters work much like sunglasses do, by absorbing the laser light and reducing the laser power often times by several orders of magnitude when used in series.

  • Beam Splitters

    Reduction of the laser power before reaching the camera is often times required to obtain a usable signal, one that is not saturating or damaging the camera. These beam splitters are designed to reflect the laser’s signal at single-digit percentages and can be used in series to greatly reduce the laser light before being imaged.

  • Neutral Density + Beam Splitter Combo

    Reduction of the laser power before reaching the camera is often times required to obtain a usable signal, one that is not saturating or damaging the camera. These systems reduce the laser power by first sampling the beam, one or multiple times, and then absorbing the beam with optical density filters.

  • Beam Expanders and Microscope Objectives

    When imaging small laser beams, the resolution of the imager becomes an issue. Pixel size of the Spiricon camera or the slit side of the NanoScan head being used must have a large enough image to properly analyze the signal being presented to it. Beam Expanders and Microscope Objectives are the way to increase the size of the beam for more accurate measurement and analysis.

  • Beam Reducers

    When imaging larger laser beams, fitting the beam on the imager becomes an issue. Array size of the Spiricon camera or the detector size of the NanoScan head being used is the limiting factor of how large the beam can be to properly analyze. Beam Expanders are the best way to decrease the size of the beam for the best measurement and analysis.

  • Lenses for Front End Imaging and Spacers

    There are times where beams are simply too large to profile with conventional methods of directing the beam, or a sample of the beam, into an imager for analysis. In this case, an imaging lens can be fixed to the front end of the imager and focused down to a plane where the beam is being projected.

  • Reimaging Products for UV Lasers

    Beam profiling of UV lasers are often times difficult on the equipment used for imaging the beam because of the wavelengths that these lasers operate at. These reimagers are offered as a way to overcome this problem. By converting the UV laser into a visible wavelength, the profiling of the laser becomes easier.

  • Near Field Profilers

    Near field profiling can be used with either camera profilers or scanning slit profilers to analyze small beams, and involves a microscope objective lens to image the beam onto a detector. This technique expands the measurement range of the camera to include smaller beams, which could not be ordinarily measured due to the pixel size of the detector array. Near field profiling is performed in fiber and waveguide analysis, lens characterization, and other applications where beams 50 microns or smaller are analyzed.
