PD300RM-UV

7Z02479
 
Description: 

The PD300RM-UV LED and laser radiometer replaces traditional radiometers which are calibrated to a single wavelength (254nm, 365nm, etc.), offering calibration over a broad spectral range, which the user can access by entering any wavelength in the calibration range. The PD300RM is a general purpose circular geometry photodiode irradiance and dosage sensor with an 8mm aperture and a cosine corrected diffuser. Its spectral range is 200-850nm and its irradiance measuring range is 100nW/cm² - 250mW/cm². The sensor comes with a 1.5 meter cable for connecting to StarBright & StarLite meters or Juno+ PC interface.

FAQ

Can I measure white LEDs with the PD300RM?

No, white LEDs have wideband spectrum. Try the PD300CIE for illuminance (lux) measurement.

Can I measure a laser with the PD300RM?

Yes, in applications where a laser beam is diverging or diffused, such as laser projectors, PD300RM can be used to measure the irradiance with high accuracy. However, it is not applicable for measuring a collimated laser beam. Use the PD300 for that.

Can I measure a mercury lamp with the PD300RM-UV?

No, the PD300RM is a broadband detector. It doesn’t have a filter to isolate specific emission lines such as mercury lamp lines (365nm, 254nm) or spectral bands such as UVA, UVB. Custom solutions with filters are available; contact Ophir for more information.

What is the accuracy of the PD300RM for LEDs and for lasers?

The accuracy when measuring irradiance of laser sources is easy to determine because lasers have very narrow bandwidth and their wavelength is well known. The accuracy for laser measurement is given in the specifications. When measuring the irradiance of LED sources, other issues such as bandwidth and wavelength tolerance come into play. For more details and specifications see the white paper.

What is the purpose of the PD300RM's diffuser?

In order to get a good cosine corrected response, a diffuser is placed in front of the photodiode to convert directional light into lambertian diffused light, thus eliminating any sensitivity to direction.

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.

Measuring LED Irradiance and Dosage with the PD300RM Measuring LED Irradiance and Dosage with the PD300RM
Measuring Power of LEDs: UV, Visible and NIR Measuring Power of LEDs: UV, Visible and NIR Measuring Power of LEDs: UV, Visible and NIR

Measuring the emitted power of an LED can be tricky; it is different in some important ways from measuring the power of a laser beam. This video shows you how to use the Ophir 3A-IS Integrating Sphere Sensor, along with the Auxiliary LED accessory, to easily make accurate measurements in LED applications.

Does your application involve irradiating a target surface with an LED? UV curing of adhesives is one example of such an application. Ophir’s new PD300RM sensor family measures irradiance and dosage for UV and Visible LEDs. This video explains what the PD300RM does, what is so unique about it, and how to use it.

White Paper – Measuring LED Power and Irradiance with Calibrated Photodiodes

In many industries LEDs are replacing traditional broadband light sources such as mercury, deuterium, Xenon, and quartz-halogen lamps. Systems and applications transitioning to LEDs are reengineered in terms of optics, electronics, heat management and more. Similarly, the equipment used by professionals to measure the output of these sources needs to be fitted for measuring LEDs.
