Integrating Sphere Coating Guidelines
For high diffuse reflectance requirements in integrating spheres, we detail the formulation, application and performance of barium sulfate (BaSO4) + PVA coatings, emphasizing spectral neutrality, high reflectivity and long-term stability.
- Standard application: First Standardized Application of High-Reflectance BaSO4 Coating
- Practical guide: Barium Sulfate Coating Application Manual
Application tip: Ensure clean substrate with optional roughening; use low-pressure uniform spraying at 20-30cm distance to avoid localized thickness that increases specular reflection.

Frequently Asked Questions
Q1: Why recommend barium sulfate coating for integrating spheres?
BaSO4 coating offers fine particle size and spectral neutrality, achieving high reflectance (400-700nm) with good durability, ideal for integrating spheres requiring uniform fields and low self-emission.
Q2: What are key coating application techniques?
Substrate cleaning/roughening, low-pressure spray gun, 20-30cm optimal distance, uniform movement, and clean environment for natural drying. Coating thickness and binder ratio affect reflectance and durability.
Q3: How to troubleshoot goniophotometer communication/operation failures?
Check communication parameters, emergency stop, power/cables, turntable load and driver error codes sequentially. Reinstall software or contact technical support if needed.
