Glan-Foucault Calomel IR polarizer

Calomel crystalline polarizers are the best choice for the mid-IR (5-17μm) applications requiring high Extinction Ratio (>1: 10 000) and power load light source resistance. Calomel Polarizers are commonly used to polarize unpolarized sources, attenuate unpolarized radiation, or act as a beam splitters.

The GlanFoucault polarizers take advantage of highly birefringent mercurous chloride (calomel) monocrystals to separate the ordinary and extraordinary rays.

Product Highlights:

High ER contrast (>1: 10 000)

Broadband transparency VIS to midIR (0.4μm 17μm)

Highest birefringence on the market (Δn = 0.683)

Positive uniaxial crystal (ne > no)
