1. Introduction

a. This technical requirements document is for a custom mirror to be used at the Eglin AFB, FL. The oval flat mirror will be used to develop a test system and must be drop-in replacements to an existing test system. Threshold Objective hroughout this specification. A threshold is the minimum acceptable requirement. An objective is a desired capability.

b. Contractor proposals should identify any specifications that are not technically feasible or have an undue impact on cost. Should this occur, proposals should provide recommended alternatives to the identified specification as well as impacts on overall system performance and cost.

2. Physical Requirements

a. Mechanical Properties. In general and if not stated otherwise, mechanical properties shall be comparable to or better than the current Pyrex mirrors and custom aluminum mounts.

b. Mechanical Robustness. The mirrors and mounts must be able to operate in a dynamic motion environment and withstand up to 15 g lateral accelerations without damage.

c. Dimensional Stability. The components shall be dimensionally stable for 45-90 degrees Fahrenheit and 10-100% relative humidity.

d. Water Resistance. The components are required to have minimal water absorption with a goal of no absorption (non-hygroscopic). The components dimensional and mechanical characteristics shall not be affected by any absorbed water.

e. Chemical Resistance. Proposals shall indicate any chemical sensitivity of the mirror and mount materials. As a goal, the components should be chemically inert and not absorb or be affected by hydraulic fluids, common electronic and electrical component cleaning sprays, spray dusters, or chemicals normally used to clean optics, including water, alcohol, ammonia, and acetone.

f. Out-gassing. The components shall not out-gas products that would damage sensitive electronics, optics, or optical coatings.

g. The oval flat mirror physical volume shall be .

h. The oval flat shall be assembled at the contractor facility using a GWEF supplied backing plate.
