T echnical SupportOperationalExcellenceSuperior CustomerServiceWarrantyOn-Time DeliveryC24 ProgramProduct Reliability For over 40 years, Coherent has been supplying you with the best laser measurement and beam diagnostic equipment available. We realize that while technical specifications greatly influence your purchasing decisions, you also must consider many other important criteria. In a recent customer survey we found that Product Reliability, Speed of Responsiveness, and Technical Support are the three top criteria when choosing a laser test and measurement supplier. That’s why we place...

With their unique combination of superior performance and user-friendly convenience, EnergyMax sensors are your best choice no matter what your particular laser energy measurement need. EnergyMax sensors are highly linear in terms of repetition rate, laser pulse width, and measured energy. They are also accurate across a broad range of wavelengths due to onboard...

6 Superior Reliability & Performance • www.Coherent.com • LMC.sales@coherent.com All pyroelectric EnergyMax sensors incorporate a diffuse coating to minimize specular reflections and eliminate spurious beams that can re-enter the laser cavity. In addition, all EnergyMax sensors include onboard electronics that contain built-in wavelength compensation factors. Enter the wavelength of the laser being measured into the software and this will automatically compensate for the sensor output. The chart below plots the typical absorption percentage of each coating. W avelength (ìm) 0.1 20 10 1 0.1...

• Toll Free: (800) 343-4912 • Tel: (408) 764-4042 • Fax: (503) 454-5727 7 Overall measurement accuracy is a combination of calibration uncertainty (found in the sensor specification tables) and the wavelength compensation accuracy (found in the “Wavelength Compensation Accuracy” table, below). The combined accuracy is based upon practices outlined in the National Institute of Standards Guidelines for Evaluating and Expressing Uncertainty (NIST Technical Note 1297, 1994 Edition). The combined accuracy of the measurement is calculated by using the law of propagation of uncertainty using the...

The maximum repetition rate is primarily dependent upon the thermal resistance of the coating and the maximum pulse width the sensor is designed to measure. Refer to the summary table on page 10 for maximum laser pulse width limitations. Model Rep. Rate (pps) 1 10 100 1000 10,000 J-10SI-HE up to 10,000 J-50MB-HE & -LE up to 300 J-25MB-HE & -LE up...
