Brewster Windows Optical Windows
from Newport MKS
The BQW-1 Brewster Window is made with UV grade fused silica with laser grade surface quality and parallelism to make it the ideal polarizer to use within a laser cavity. The BQW-1 has a 22.11 mm major axis, a 12.5 mm minor axis, and is 2.0 mm thick. When oriented at the 55.57 ° Brewster's... [See More]

from Rainbow Research Optics, Inc.
Optical Windows are often used to create a physical barrier between two different environments – preventing two gases from mixing together, separating liquids from the air, keeping a sealed system in a vacuum. In many optical systems, a window is used to protect more expensive optical... [See More]

from Changchun Sunday Optics Co., Ltd.
Calcium fluoride has a high transmittance from ultraviolet to mid-infrared (250nm~7um), so it is widely used in the manufacture of prisms, Windows and lenses, In some applications with a wide spectrum range, it can be used directly without coating film, Especially, it has low absorption and high...

from Rocky Mountain Instrument/RMI Laser
Brewster Windows are windows designed for use at Brewster's angle (usually uncoated). This is the angle where only incident p-polarized light has 0% transmission loss. They are an economical option for coupling linearly polarized light into sealed optical systems and to select the polarization of... [See More]

from Rocky Mountain Instrument/RMI Laser
Brewster Windows are primarily used in laser cavities to produce a beam with a high degree of polarization purity. When unpolarized light is incident on an uncoated substrate at Brewster ’s Angle, the reflected portion is completely S polarized and the transmitted portion is partially P... [See More]
