Optical Flats
from EKSMA OPTICS

Optical flats are used for testing and evaluating other optical elements. An interference pattern is formed in the air between the flat and the object being evaluated, and this pattern is usually more seen through the flat than through the object. The pattern consists of alternating bright and dark... [See More]

Parallel Windows
from Rocky Mountain Instrument/RMI Laser

Parallel Windows are similar to Plane Windows, but with parallel surfaces. These windows are well suited for applications in which angular deviation of the transmitted beam must be kept as small as possible. Misalignment errors are also minimized when the window is repeatedly inserted and removed. [See More]
