• General lab and shop reference mirror
• Flat to 1/10 wave over working surface
• Adjustable to fractions of one second
• Flatness certified traceable to NIST

The Model D-569 Adjustable Reference Mirror provides a clear 12 inch (305 mm) diameter working surface.  The adjustment screws tilt the mirror approximately 1.0 arc second for each 1° turn.  A series of Model D-569 or Model D-571 mirrors are often used for the purpose of simulating long distances.  Both mirrors are basic tools recommended for any laboratory or precision shop, and most aerospace ground support installations.
