Hi Charles, I was able to find exactly what I was looking for through Labsphere--thank you! For anyone who is interested, this type of integrating sphere can be found at the following link: https://www.labsphere.com/product/reflectance-transmittance-spheres/

I am looking for a specific type of integrating sphere that can be used to capture diffuse reflectance measurements, and I would appreciate help with locating a commercially availably version of this sphere. The diagram below illustrates the type of sphere I am looking for [1]. Two ports are...

Yes, the beam will be slightly larger than the object (I will use an aperture to limit the beam diameter). To eliminate the section of the beam that is not illuminating the insect, I plan to either use a transparent mounting slide with a light trap behind it or a slide made out of a highly...

https://nvlpubs.nist.gov/nistpubs/Legacy/MONO/nbsmonograph160.pdf Based off of these definitions, I need to measure the directional-hemispherical reflectance.

Can you elaborate on what you mean by directional-hemispherical reflectance vs. hemispherical-directional reflectance?

I am designing an experiment to measure the reflectance (diffuse+specular) of insect specimens, and I plan to use an integrating sphere to collect the measurements. Typically, I have seen that reflectance measurements with integrating spheres are done with planar (i.e. flat) sample objects. So...
