Key Features
Meadowlark Optics manufactures Precision Linear Polarizers using dichroic sheet polarizer material laminated between high-quality glass substrates (BK 7 material, λ/10 flat). For visible wavelength polarizers, this construction produces a total transmitted wavefront distortion of less than λ/5.
We use various polarizer materials to cover wavelengths between 320 and 2000 nm. Both visible and near-infrared polarizers are supplied with a high-efficiency, broadband antireflection (AR) coating; single‐layer AR coatings are optional on our ultraviolet polarizers.
Both mounted and unmounted Precision Linear Polarizers are offered as standard products. Meadowlark Optics Precision Linear Polarizers have their transmission axis clearly marked.Polarizer Material: Dichroic Polymer

Custom AR coatings are available on all polarizers. For NIR2 polarizers, choose from the following AR coatings:
NIR2 – 1 covers 650 – 950 nm
NIR2 – 2 covers 900 – 1250 nm
NIR2 – 3 covers 1200 – 1700 nm
Prolonged exposure to strong ultraviolet radiation may damage these polarizers. Custom coatings are available.
