Application Example: Poisson’s Spot

26.11.2016 , FRED Knowledge Base

Figure 1. Poisson’s spot irradiance pattern. A 588 nm coherent plane wave source shines behind a circular obstruction with 0.1 mm radius. Coherent irradiance is evaluated at two different distances: On the left side, light 2 mm beyond the obstruction does not undergo significant...

Application Example: Bessel Beam Generation

05.08.2016 , FRED Knowledge Base

Bessel beams are a special type of light propagation that does not diffract. The light distribution of a Bessel beam maintains a tight focus with high irradiance over great distances. Bessel beams are also self-healing, which means that the light pattern will regenerate after being...

Application Example: Color Mixing Lightpipe

05.08.2016 , FRED Knowledge Base, Sources

LEDs, have surpassed incandescent light sources in recent years for most applications. Benefits of the LED include compact size, high power efficiency, and a long lifespan. LEDs also have undesirable qualities that optical engineers must address, such as the need for color mixing and collimation....

Application Example: Dichroic Cold Mirror

05.08.2016 , FRED Knowledge Base

The spectral distribution of a broadband light source is important to many optical systems, from white light illuminators to spectrometers. Color Image analysis in FRED produces visualization of color distribution by calculating chromaticity coordinates of each pixel and displaying the resulting RGB values over the...

Application Example: Fizeau measurement of lens surface

05.08.2016 , FRED Knowledge Base

FRED allows for simulation of physical optics phenomena such as diffraction and interference. With this capability, components such as Gaussian laser beams and interferometers can be accurately modeled and incorporated into optical systems. A full description of this application example can be found here: Fizeau measurement...

Application Example: LED Flashlight

05.08.2016 , FRED Knowledge Base, Sources

Light Emitting Diodes, or LEDs, have surpassed incandescent light sources in recent years for most applications. Benefits of the LED include compact size, high power efficiency, and a long lifespan [1]. LEDs also have undesirable qualities that optical engineers must address, such as the need...

Application Example: Maltese Cross Phenomenon

05.08.2016 , FRED Knowledge Base, Sources

FRED has the capability to simulate polarization of rays through an optical system. Light sources can be randomly, circularly, or linearly polarized. Optical components that filter or manipulate polarization, such as birefringent wave plates and polarizers, can be accurately modeled. One simple example of polarization...
