كرة نقل 4 بوصة - موزع F/45 - 1/10 موجة

Took a chance on this F/45 diverger for my interferometry setup and the 1/10 wave spec holds up in testing—fringes are crisp and stable. Fit onto the 4" mount without any fuss.

The F/45 diverger gives a clean, repeatable reference wavefront right out of the box, and the 1/10 wave specification is no exaggeration. It's been perfect for testing my faster mirrors without introducing noticeable spherical aberration.

The 1/10 wave PV spec holds up in practice—the fringes stayed clean and stable across the full aperture during my test setup. It’s a pricey accessory, but for anyone needing a precise slow diverger, this one earns its keep.
