LISUN employs <strong>BaSO\u2084 (Barium Sulfate) or PTFE-based diffuse coatings<\/strong>, achieving reflectance rates exceeding <strong>95%<\/strong> in the visible spectrum. Labsphere typically uses proprietary <strong>Spectraflect\u00ae or Spectralon\u00ae coatings<\/strong>, which offer similar reflectance but may differ in long-term stability under high-intensity testing.  <\/p>\n<p>The LPCE-2\/LPCE-3 systems feature <strong>molded sphere designs with minimized seam interference<\/strong>, reducing measurement deviations caused by structural inconsistencies. Labsphere spheres often utilize segmented construction, which may introduce minor reflectance variations.  <\/p>\n<p>\u0625\u0646 <strong>LPCE-2\/LPCE-3<\/strong> supports a <strong>380\u2013780nm spectral range<\/strong> (extendable to 200\u20132500nm for specialized configurations), aligning with <strong>CIE 177, CIE-13.3, and IES LM-79<\/strong> standards. Labsphere spheres typically cover similar ranges but may require additional calibration accessories for extended UV or IR applications.  <\/p>\n<p>Calibration traceability is critical for compliance with <strong>NIST, DIN, and ISO 17025<\/strong> standards.
