The L30C-LP2-26-SH is a compact thermal power/energy laser measurement sensor for freestanding use or mounted to host system. It has a 26mm aperture and can measure from 300mW to 10W stand alone and to 100W when heat sinked. It can measure energy from 30mJ to 2000J. The sensor is able to measure high power lasers of up to 4kW by measuring the energy of 0.5 - 4s exposure to the laser. The high damage threshold LP2 absorber covers the spectral range from 0.25 to 2.2µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

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?
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.Close
In this video, Jimmy Green, Ophir OEM Specialist, explains how Ophir can solve laser measurement challenges if a solution cannot be found from the hundreds of products in our catalog.
Sometimes, even experienced users of laser measurement equipment come across some issues that, although basic, need to be clarified. This video reviews 2 such issues.
In this video, you will learn some guidelines for making sure that a sensor has been provided with proper heat sinking so it does not get damaged.
