What is the difference between the Glan-Taylor and the Glan Thompson Polarizing Prisms?
Both of these products take un-polarized input and convert it to linearly polarized output. The main difference is the Taylor is air spaced and the Thompson is cemented. The advantage of the cemented prism (Glan-Thompson) is that it has a greater field of view (as great as 24 degrees depending on length). The air spaced prism (Glan-Taylor) only has around a 10 degree field of view. The advantage of the air spaced is that it has a higher transmission than the cemented Glan-Taylor.
