Product Description
M5XX VIEWING 450 10584-2 Precision Optical Component – Aerospace/Defense Grade Surplus
This used M5XX VIEWING 450 10584-2 is a specialized optical component with markings consistent with high-reliability aerospace or military applications. The “VIEWING 450” designation suggests it is a sight, window, lens assembly, or prism designed for observation, imaging, or targeting systems operating at a specific 450 nm (blue) wavelength or possessing a 450 mm focal length.
The number “10584-2” correlates with a specific “B*” drag term (a “b-star” value of 0.0010584) found in U.S. Government satellite tracking datasets . This indicates the part originated from a defense or space contractor involved in satellite tracking, telemetry, or optical ground station equipment.
Condition Note: This unit is untested and sold as-is. The optical surfaces should be inspected for clarity.
