Polaroid Filter, 50mm Round, Mounted In Holder, Pack of 2

The Polaroid Filters are securely mounted in a graduated holder, allowing precise control of polarisation effects on an optical bench.

When the polaroids are aligned, the transmission is 38%. However, a significant reduction to less than 0.2% occurs when they are misaligned at 90°, causing an almost complete blackout.

To change the transmission from maximum to minimum, one can rotate one filter relative to the other by moving the pointer to ±90° while holding the front ring. The filters feature a robust metal stem, ensuring secure attachment to a clamp or an optical bench for stable and reliable experimentation with polarised light.
