6080 White Reflectance Coating

Labsphere 6080 White Reflectance Coating

A diffuse reflectance paint descended from Kodak 6080 & Munsell coatings

Labsphere 6080 is a scientific-grade, barium sulphate-based paint that exhibits near-perfect diffuse reflectance at levels up to 98% in the 250-2500nm (UV-VIS-NIR) wavelength range. Available as a pre-mix or in an ethanol solution, 6080 is used to coat integrating spheres, lamp housings, backlight reflectors and laser pumping chambers, in fact anywhere where you need efficient, uniform illumination.

98% Diffuse Reflectance for Efficient, Uniform Illumination

6080 white reflectance coating is a pre-packaged paint that exhibits extremely diffuse, high reflectance. It is applied by spray painting to almost any substrate (metals, plastics, glass) for use in integrating spheres, laser cavities, lamp reflectors and display backlights. It is characterised by a near-perfect Lambertian (i.e. diffuse) reflectance of up to 98% in the spectral range from 250-2500nm. 6080 coating is a barium sulphate-based formulation similar to Labsphere's Spectraflect and Duraflect coatings. Whereas Spectraflect and Duraflect are offered as coating services only, 6080 is sold as a paint for the customer to apply to their reflectors. 6080 can also be used to repair minor damage to painted integrating spheres.

Your Choice: Ready Mixed or Alcohol Free

6080 coating is supplied as standard as an ethanol solution, ready mixed for customer use. Due to restrictions imposed by freight forwarders on the transportation of flammable materials, we also offer 6080 as a coating "pre-mix". This is a more economical alternative and the premix formulation need simply be mixed with the appropriate volume of spectroscopic grade (200 proof) ethanol prior to painting. For further information, consult the Application Instructions which you can download from the Knowledge Base box above.

The ready mixed 6080 white reflectance coating is available in 0.5 and 1.0 litre bottles. The premix formulation is stocked in 0.25 and 0.5 litre bottles which require mixing with an approximately equal volume of ethanol. At the optimum coating thickness of 0.5 to 0.6mm, 1 litre of 6080 paint (or of the premix + ethanol solution) will cover an area of approxmately 2,500cm². The coating is best applied using an airless spray gun or (for small area use) by an airbrush. The high, diffuse reflectance provided by 6080 cannot be generally achieved by applying the paint by brush, except for small area repairs to integrating spheres. Pro-Lite normally holds stock of 6080 premix available for next working day delivery in the mainland UK.
