MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® PD300-MS microscope slide power meter for accurate measurements of light emitted from fluorescence microscopes.
The PD300-MS measures power levels of high numerical aperture (NA) objectives, from 5µW to 1W. A special filter provides low angular dependence, enabling higher accuracy measurements. NIST-traceable calibration allows for measurement of wavelengths from 350nm to 1100nm. The power meter is designed for use with a wide range of light sources in such applications as photoactivation or photobleaching. To accommodate limited space, it has the same footprint as a standard microscope slide. The PD300-MS can be used at the sample plane in air or with water/oil immersion objectives without damage.
"A precisely defined amount of applied power is crucial for the repeatability of fluorescence microscopy experiments; however, the power output of light sources changes over time," said Isabelle Okashi, PhD, General Manager, Ophir Photonics Israel. "Using the PD300-MS, an accurately calibrated power meter, in the object plane makes it possible to measure the exact amount of light applied to a specimen, regardless of the light source or optical details of the microscope."
The PD300-MS is compatible with all Ophir meters and PC interfaces, including Centauri, the portable laser power/energy meter with a large, sophisticated graphical display and advanced math functions.
