B -- BI-DIRECTIONAL REFLECTANCE DISTRIBUTION FUNCTION (BRDF)MEASUREMENT SERVICES AND MEASUREMENT EQUIPMENTN/ POC Lt Louis Orndorff, Contract Specialist/Mr David Castillo, Contracting Officer (505)846-4055 The Air Force Research Laboratory frequently has requirements for BRDF measurements on a variety of materials ranging from dark, diffuse paints to highly reflective, highly specular materials. While we have limited in-house, contractor operated measurement facilities, demands for data often exceed our measurement capability. While no current requirement has been identified or funded, we are interested in determining what measurement capability exists within industry and at universities and determining what commercial or semi custom BRDF measurement equipment is available. (a) We frequently require measurements at wavelengths between 632.8 nanometers and 10.6 micrometers, and also require data at long wavelength ultraviolet and visible white light. To assist our programs with future requirements for BRDF measurements, we are requesting information on BRDF measurement capabilities to include wavelengths available, noise floor, detector field of view, measurement type (AC or DC), polarization, sample sizes, incident beam characteristics, turn-around times and cost per sample. (b) We are requesting information on what BRDF measurement equipment is available for purchase to meet all or some of the above listed requirements. (c) In addition, we are interested in receiving information on commercial products and services as well as commercial practices. Respondents are requested to provide a statement of capabilities and information about current business practices related to BRDF measurements and equipment. If any price lists or catalogs are available, include them with your response. Request all pertinent information and three copies of your response be submitted by March 15, 1999. All responses should be forward to AFRL/DE, Attn: Lt. Louis Orndorff, 3550 Aberdeen SE, Kirtland AFB, NM 87117-5776. Questions may be sent to the same address or call (505) 846-4055.!!
