PSL Spheres: Precision Calibration Solutions

Introducing the PSL Spheres, a cutting-edge calibration solution for laser and liquid particle counters. These highly uniform polystyrene microspheres are meticulously calibrated within nanometers, ensuring precise and reliable measurements. The 15ml bottle contains a NIST traceable size standard with a very narrow peak standard deviation, making them ideal for accurate size calibration.
  • Uniformity: The spheres are highly uniform, ensuring consistent and reliable measurements.
  • Traceability: NIST traceable size standards for size traceability and calibration confidence.

Technical Specifications and Properties

The PSL Spheres are available in a 15ml bottle, providing convenient and easy-to-use calibration solutions. Each sphere has a density of 1.05 g/cm3 and an index of refraction of 1.59 @ 589 nm, measured at 25 degrees centigrade. The spheres are calibrated with traceability to NIST SRM size standards, ensuring the highest level of accuracy.
  • High Density: 1.05 g/cm3 for consistent and reliable measurements.
  • Refraction Index: 1.59 @ 589 nm for precise calibration and measurement.

Practical Applications and Benefits

The PSL Spheres are designed for a wide range of applications, including the calibration of electron and atomic force microscopes, KLA and Hitachi wafer inspection systems, and laser particle counters. These standards are also used to create aerosol size challenges for calibrating the size response of laser particle counters. With a size range of 100 nm to 100 microns, the spheres can be used directly from the bottle without any dilutions.
  • Applications: Suitable for various calibration needs in the semiconductor industry and beyond.
  • Convenience: Direct use from the bottle without dilution for time-efficient calibration.
