Subject: FA8224-17-R-0056

Clarification

Below are response to questions regarding subject solicitation.

Black backing required - Spray Paint / Screen Printed?

Government Response : As Long as the back is Black and opaque the process does not matter to us.

Dimensional tolerances required - We would prefer to have +/- .125"

Government Response: Yes, it is okay to allow for this much tolerance, no problem.

Edge finish - Is a cut edge OK or do you need the edges safety seamed?

Government Response: The cut edge is OK, we tape the edges before putting into a aluminum frame.

One mirror, out of the 9 listed, is 3mm thick. We do not stock 3mm in a size that is larger than 32" x 50" so we would need to deviate to 6mm. This is for item 7 on your inquiry. Is 6mm OK?

Government Response: All of the mirrors should be the same thickness if one was wrong on the specification it was in error, make all mirrors on order the same thickness of 1/4 inch or 6mm.

What is the optical density number?

Government Response: This was not in our specification, this should answer this.

An average reflectance of 88% or greater in the 450 nm - 700 nm visible light band, approximately visually neutral in color balance.
