High Reflectance Diffuse Optical Coatings

Avian-B White Reflectance Coating

Avian-B coating is a water based barium sulfate coating similar to Eastman 6080™ White Reflectance Coating. The coating is highly lambertian and exhibits reflectance of >97% over from 350-850 nm and greater than 92% from 250-1300 nm The coating is easily applied to most metal substrates and can be applied to other materials with proper surface preparation. The applied coating is stable from -40 degrees C to +90 degrees C. This coating is primarily designed for laboratory, as opposed to field, applications.

Avian-B is a well characterized coating that has been used for diffuse reflectance applications for more than 20 years. It is relatively easy and inexpensive to apply.

 Applications:
  • Integrating spheres
  • Line and cylindrical scanners and illuminators
  • Reflective diffuser panels
  • Reflectance standards for laboratory and remote sensing applications
  • Collection spheres for fiber optic evaluation
  • Any place a high reflectance coating is needed for a laboratory application

Avian-B coating is available as either bulk coating or as coating services. Bulk coating comes shipped with preparation and coating instruction The coating comes shipped without the alcohol propellant/co-solvent, which is specified. This allows us to keep our prices low. One liter of Avian-B premix coating makes approximately two liters of finished coating.

Avian-D White Reflectance Coating

Avian-D coating is a recent development by Avian Technologies. The two-part water based urethane coating uses a different pigment system than Avian-B and can be applied to a wide variety of substrates. The applied coating is also water proof and quite durable.

The coating is a two part coating with a water phase with pigment and an activator. The pot life is approximately 48-72 hours after mixing.

The shelf life of the unmixed coating is 1-2 years.

The reflectance of Avian-D coating matches that of barium sulfate based coating in the visible region of the spectrum. The coating is also quite useable down into the near-UV and in the very near-IR.

Avian-D coating is ideal for field applications where the coating will experience variations in temperature and humidity, such as calibration plates and remote sensing targets. The coating is also ideal for large integrating spheres used in lamp measurement photometry where large amounts of UV are not present. The coating is stable over the range -40 degrees C to about 85° C.

 Applications:
  • Integrating spheres
  • Line and cylindrical scanners and illuminators
  • Reflective diffuser panels
  • Remote Sensing targets
  • Reflectance standards for laboratory and remote sensing applications
  • Collection spheres for fiber optic evaluation
  • Any place a high reflectance coating is needed for a lab or field application
