The Optical Constants window is used to set the source position and optical parameters for the detector.
The next step is to enter the x,y,z source position (in centimeters) into the Optical Constants window.
To perform an interactive optical calibration, first change the display to calibrated hits in the Data menu, then sum an entire run of events for a specific source location.

 Lightwave - Optical-fiber window-stripping: Why and how?
This type of operation is known as a "window strip." The typical fiber on which window-stripping is performed has a cladding diameter of 125 microns and an acrylate coating thickness of 250 or 400 microns.
A window is stripped in the fiber to begin the process.
There are two major applications that require a window strip to be performed as part of their manufacturing process.

 Optical window
In astronomy, the optical window is that portion of the electromagnetic spectrum that passes through the atmosphere all the way to the ground.
The window runs from around 300 nanometers (ultraviolet-C) at the short end up into the range the eye can use, roughly 400-700 nm and continues up through the visual infrared to around 1100 nm, which is thermal infrared.
There is another window called the "radio window" that lets through some (not all) radio waves.

 Patent 4018513: Optical window used in device for monitoring clarity of a fluid
Even if the candlepower of the light bulb changes or the optical windows foul up, total or summed charging voltage of the measurement capacitor will stay the same because the changes in light captured are the same for both photocells.
In this way, the reference cell 20 looks through the same number of optical window as the measurement cell 16; and all the optical windows are similarly exposed to fouling conditions.
Light-accepting windows 22 and 24 as well as light-transmitting window 26 in casing 21 adjacent light source 14 are shielded by perforated covers 28 which maximize the velocities of the fluid air streams and equalize them over the area of the covers.

 Definition of Microwave
Note: above 300 GHz, the absorption of electromagnetic radiation by Earth's atmosphere is so great that the atmosphere is effectively opaque to higher frequencies of electromagnetic radiation, until the atmosphere becomes transparent again in the so-called infrared and optical window frequency ranges.
Heinrich Hertz was the first to demonstrate the existence of electromagnetic waves by building apparatus to produce radio waves.
Microwaves can be generated by a magnetron or a

Wavelengths in the range visible to the eye occupy most of the "optical window", a range of wavelengths that are easily transmitted through the Earth's atmosphere.
Between 300 GHz and the mid-infrared, the absorption of electromagnetic radiation by molecular vibration in the Earth's atmosphere is so great that the atmosphere is effectively opaque to electromagnetic radiation, until the atmosphere becomes transparent again in the so-called infrared and optical window freqency ranges.
However, there are certain wavelength ranges ("windows") within the opaque range which allow partial transmission, and can be used for astronomy.

 Picture generation on the optical window
We know the plane and the ribonn in which the hit is. Thanks to a previous mapping, we are able to determine in which optical window the hit will be.
We calculate the position of the illuminated fiber on the optical window thanks to the layer number and the fiber numbre recorded previously.
The position of the hit is then generated using a uniform random distribution on the illuminated fiber surface on the optical window.

 Portable optical scanning device with a recessed optical window
A hand-held scanning device is disclosed in which the scanning device housing window has a recessed optical portion of the window formed such that the recessed optical portion of the window does not come into contact with the object being scanned while a scan is being performed.
This recessed optical portion of the window eliminates damage caused by contact with the object being scanned to the optical portion of the window.
The recessed portion of the window is formed without corners in such a manner that it may easily be wiped clean by the end user without dirt, dust and the like building up in corners of the recess.

 Optical Illusions and Visual Phenomena
»Optical illusion« sounds pejorative, as if exposing a malfunction of the visual system.
These pages demonstrate visual phenomena, called »optical illusions« or »visual illusions«, the latter more appropriate IMHO.

Scientists at the Jet Propulsion Laboratory are particularly interested in the south pole of the Moon as an optical astronomy site, because the cosmic southern hemisphere is particularly rich in objects of interest to modern astronomy (22).
Other candidate products for space processing experiments on the Shuttle and Spacelab include electronic components (such as pure crystals for semiconductors and silicon ribbon for integrated circuits), improved turbine engine blades, and advanced optical products for laser systems.
Astronomers thus will be able to resolve objects five to ten times smaller in angular diameter than those subject to ground-based optical observations.

 ClearView VHW Series Self-Cleaning Optical Window (Viewport)
The windows consist of an in-vacuum heated quartz disk, thermally isolated behind a standard vacuum window.
Material that would normally cloud or obscure the view through a vacuum window encounters the protective heated disk instead.
The ClearView™ VHW Series windows are self-cleaning viewports for use in deposition environments.
