What is collimated LED?
The Collimated Backlight Series is a high performance, uniform, and collimated light source for high precision silhouetting and transmissive applications. These lights utilize a full array LED layout with more LEDs per square inch to provide greater intensity and uniformity. …
What is a collimated light source?
A collimated beam of light or other electromagnetic radiation has parallel rays, and therefore will spread minimally as it propagates. Thus, as the distance from a point source increases, the spherical wavefronts become flatter and closer to plane waves, which are perfectly collimated.
How do you make a collimated beam?
To produce collimated light you can either place an infinitesimally small source exactly one focal length away from an optical system with a positive focal length or you can observe the point source from infinitely far away.
What is a beam projector used for?
Beam projectors are often used to create a godspot effect. The beam projector no longer is used to the extent that it once was, as newer fixtures and PAR lamps have created easier ways to produce the effect.
Is LED light collimated?
Collimation is never perfect, especially with LED sources, because they are not point sources. Accept some divergence in the collimated beam. High-power LEDs suitable for illumination are significantly different from small-indicator LEDs.
Is collimated light polarized?
The polarization of the collimated light is modified using a linear polarizer and a linear retarder of 89.6° retardance at 580 nm. Different polarizations of light at normal incidence illuminate the DoFP polarimeter …
What are the differences between collimated and coherent light?
In simpler terms, coherent means that every ray of light is accurately phase-synchronized with each other. Monochromatic means that the light must be composed rays of exactly the same frequency. Finally collimated means that every ray would have exactly the same direction of travel.

How do you know if light is collimated?
We can assume that light is collimated or coming from infinity, if the light source is greater than a distance equal to 10x the focal length of the lens away.
Is sunlight collimated?
Incoming direct sunlight at the earth’s surface is treated as a beam with an angle of collimation of ∼0.5° and thus is essentially parallel to ±0.25°.
How is collimated light used in precision optics?
Using precision optics, the light is collimated in both the X and Y dimensions. The light exits at a low divergence angle making it perfect for applications requiring high precision measurements when used with a telecentric lens.
What are the different colors of collimated lights?
These lights utilize a full array LED layout with more LEDs per square inch to provide greater intensity and uniformity. The Collimated Backlight is available in White, Red, Green, Blue, and IR with independent color control.
How are collimated light sources used in silhouetting?
The Collimated Backlight Series is a high performance, uniform, and collimated light source for high precision silhouetting and transmissive applications. Using precision optics, the light is collimated in both the X and Y dimensions.
How big does a collimated backlight need to be?
The Collimated Backlight is available in White, Red, Green, Blue, and IR with independent color control. Active areas ranging from 1 inch x 1 inch (25 mm x 25mm) to 12 inches x 12 inches (305 mm x 305 mm). Custom sizes up to 3 feet x 3 feet (1 m x 1 m) are available.
