optical window

It is used as an infrared optical window and a solar cell material.

It can be used planar as an optical window or shaped into a lens.

A common use of synthetic sapphire is in sapphire optical windows.

Its monocrystals can be used as optical windows and high-quality sputter deposition targets.

It is used widely as infrared optical windows and components for general spectroscopy because of its wide spectral range.

The sight can be adjusted for range and windage by simply tilting or pivoting the optical window.

Data gently corrected, "The reinforced optical window allows visual access to the matter-antimatter reaction assembly."

In medical physics, the optical window is the portion of the visible and infrared spectrum where living tissue absorbs relatively little light.

The IU had an optical window to allow alignment of the inertial platform before launch.

It then returns to one of six quartz optical windows in the floor of an optical laboratory at ground level.

The optical window is also called the visible window because it overlaps the human visible response spectrum.

The optical window in a holographic weapon sight looks like a piece of clear glass with an illuminated reticle in the middle.

Sapphire optical windows can be polished to a wide range surface finishes due to its crystal structure and it hardness.

The sight's parallax due to eye movement is the size of the optical window at close range and diminishes to zero at the set distance.

In astronomy, the optical window is the optical portion of the electromagnetic spectrum that passes through the atmosphere all the way to the ground.

An optical window may be built into a piece of equipment (such as a vacuum chamber) to allow optical instruments to view inside that equipment.

This is compensated for by keeping the dot in the middle of the optical window (sighting down the sight's optical axis).

The availability of wavelengths for remote sensing and imaging is limited by the infrared window and the optical window.

The optical window can be computed based on the absorption coefficient spectrum or the effective attenuation coefficient spectrum.

Visual autocollimators are often used for lining up laser rod ends and checking the face parallelism of optical windows and wedges.

The Optical window (also known as therapeutic window) defines the range of wavelengths where light has its maximum depth of penetration in tissue.

The collimated reticle image can also be seen at any eye position in the cylindrical volume of collimated light created by the sight behind the optical window.

Visible wavelengths pass through the "optical window", the region of the electromagnetic spectrum which allows wavelengths to pass largely unattenuated through the Earth's atmosphere.

Because scattering has weak dependence on wavelength, the optical window is primarily limited by absorption, due to either blood at short wavelengths or water at long wavelengths.

As a wide direct band gap material with resulting resistance to radiation damage, GaAs is an excellent material for space electronics and optical windows in high power applications.
