L30C-LP2-26-SH | OEM thermal and photodiode sensors | OEM Power Sensors - Ophir



Der L30C-LP2-26-SH ist ein kompakter thermischer Sensor zur Messung der Laserleistung und -energie, der freistehend oder befestigt am Hostsystem verwendet werden kann. Er verfügt über eine 26mm Apertur und misst ohne Kühlung 300mW bis 10W sowie mit Kühlung bis zu 100W. Er misst Energie von 20 mJ bis 2000J. Basierend auf der Energiemessung von Einzelpulsen mit einer Dauer von 0,5-4s lassen sich Laserleistungen bis 4kW messen. Die LP2 Absorberschicht mit hoher Zerstörschwelle deckt den Spektralbereich von 0,25 bis 2,2µm ab.

Über das mitgelieferte 1,5 m lange Kabel lässt sich der Messkopf an ein Anzeigegerät oder eine PC-Schnittstelle anschließen.

I see Ophir has released some new thermal sensors with an absorber called “LP2”. What is it?

The new “LP2” type sensors are specially designed for beams having high power and high power density (and for pulsed beams, high energy density). The LP2 sensors are replacing the equivalent LP1 sensors; as impressive as the LP1 is, the LP2 was developed with the following improvements:

  • Very high damage threshold, for both power density and energy density, for long pulse and CW beams;
  • Spectrally flat; since its absorption remains constant at widely differing wavelengths, this means that sensors based on the LP2 can be used for "white light" or polychromatic beams;
  • Very high level of absorption (as high as 96%, depending on wavelength), meaning much less light is scattered back, which for high power beams is an important benefit;
  • The absorption is also largely independent of incident angle, which means it can be used for divergent beams too.

Sensor Finder does not find a match for my application. Is there the possibility to create an OEM sensor for my application?

Yes, we have the ability to rapid prototype standard OEM sensors to help with custom applications where an off the shelf sensor does not fill the requirement.

What is the dynamic range of OEM sensors?

In general, the dynamic range over a given range, i.e. the ratio of maximum useable power to minimum useable power of Ophir thermal OEM sensors is 40:1. If greater dynamic range is desired, Ophir OEM RS232 sensors are available with several selectable ranges.

Do I need to recalibrate my instrument? How often must it be recalibrated?

Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.

Pulsed Power Measurements

Ophir has a number of sensors which utilize Pulsed Power measurements. This mode enables quick and easy measurements of high power lasers with small air cooled sensors. The most advanced sensor in this category is the Helios, a specially designed sensor for the industrial environment which measures pulse widths, calculates the power of the laser, and interfaces by Profinet protocol. Weiterlesen...
