Kaiser 防牛頓環平面玻璃內嵌片 - 6 × 9 公分

I was worried about Newton rings ruining my prints, but this anti-Newton glass eliminated them completely. The flatness is perfect for holding my 6x9 negatives sharp across the entire frame.

The glass sits perfectly flat in my old K4483 carrier, and the anti-Newton surface really does kill those annoying ring artifacts on the negatives. Focus is crisp edge-to-edge, and it’s a relief not to fight with the film during printing.

I've been fighting Newton rings with my last negative carrier for years, but this flat glass insert is a total game changer. It's rigid and fits into my K4483 carrier without any shimming, and the anti-Newton surface means I can finally dry-mount proofs without seeing rainbows in the grain.
