PFHDU – High-Temperature linear polarizer

Description

This dye-type (but neutral gray) polarizer has <strong>high thermal and light flux resistance. It is used in tough field applications and to repair some <strong>projectors with damaged polarizers. It has a single pass transmission of 38%. It comes with pressure sensitive adhesive backing so it can be attached to glass. It is also offered without adhesive backing. The film is 0.2 mm thick (0.3 mm with the protective layers). It has a protective film on the front that should be removed upon application. &nbsp;It blocks UV past 380 nm.&nbsp; &nbsp;It is shipped flat. It is offered in 3 different sizes: small = 25 x 15 cm (10 x 6 in), half-sheet = 61 x 50 cm (24 x 20 in) and full-sheet = 610 x 1000 mm (24 x 39.5 inches). The transmission axis is parallel to the width on the full sheet and the small pieces, and <u>to the length on the half sheet. Single Transmission: 38.0% Parallel Transmission: 27.2% Crossed Transmission: 0.03% Polarizing Coefficient: 99.90% Super High Durability performance Heat resistance:  105C (221F) Dry for 1000 hr Humidity resistance:  80C (176F) @ 90% RH for 500 hr Lamp: 400W mercury for 500 hr Cold resistance: -40C (-40F) for 1000 hr Thermal shock: -30C (-22F) to 85C (185F), 0.5 x 1000 cycles
