نوافذ إسفينية دقيقة، زجاج بصري N-BK7*

This little wedge cleaned up the back-reflection problem I was having in my test setup completely. The N-BK7 glass seems consistently clear with no visible striae, which matters for my laser work.

I was fighting ghost reflections in my interferometer setup and these wedge windows killed them completely. The N-BK7 glass is clean with no visible striae, and the wedge angle is consistent from piece to piece. Back reflections that used to wash out my beam are just gone now.

The wedge angle did exactly what I needed — killed the back reflections that were messing with my diode setup. Glass arrived clean with no chips on the edges, and the coating looks uniform under light.
