Features

Black Anodized Aluminum Housing

The polarizer assembly is mounted in a black anodized aluminum housing for protection, with the transmission axis clearly marked. The standard one inch diameter makes mounting easy into any Newport rotation stage such as the RSP-1T or the 481-A. 

4000:1 Extinction Ratio

The laminated structure of these polarizers makes them durable and perfect for low-power 450-750 nm applications. Transmission through two Model 5511 polarizers is shown as a function of wavelength.
