The radiant intensity distribution shows that all the power lands on a single pixel in angle space, as expected for a collimated beam: At 0.555 microns, this amount of power corresponds to 683 Lumens, as shown in the True Color image. The total power is 1 Watt, consistent with the amount of power launched by the source. We can use this same detector object to determine the amount of power on the detector in Watts, simply by switching the view to False Color (or equivalent): human eye, response has been accounted for). The total power is given in Lumens, as expected for a True Color image (in which the photopic, i.e. Tracing 1 million rays in this system, the following results are found for the irradiance distribution: The wavelengths emitted by the source can also be determined by Tristimulus values, as described in the article “ How to Model Colored and Tristimulus Sources”. Which are defined in the Wavelength Data dialog box: The color of the beam shown in the Layout plot corresponds to an RGB representation of the wavelength being traced:įor the source, the wavelength traced is set by System Wavelengths: In this example, a collimated beam of light at 0.555 microns is propagated 1 mm to the Detector Color object: The archive file for this example is located at the beginning of this article. This image can be viewed in both Position Space as well as Angle Space, so we can view the True Color image of both the irradiance and radiant intensity distributions.Ī simple example in which a beam of light is used to illuminate the Detector Color object is provided in the file “Simple Example System.ZMX”. The Detector Color object can be used to visualize the True Color image of a given irradiance distribution: The main difference is that the Detector Color object stores Tristimulus data in addition to power data (and unlike the Detector Rect object, the Detector Color object does not store coherent data). The Detector Color object is very similar to the Detector Rect object. The resultant color distribution of the output image may be visualized using the Detector Color object. In this article, we’ll provide a brief overview of the Detector Color object and its associated merit function operand NSDE. As described in the article entitled “How to Model Colored and Tristimulus Sources”, a polychromatic source may be defined in Zemax either by using multiple system wavelengths or by defining the Tristimulus (or associated) values for the source. digital displays and projection systems) require knowledge of the photometric (human eye) response of the system to a broadband source. In this article we'll examine the methods used in OpticStudion to implement broadband sources, and both analyze and optimize the system performance with the Detector Color object and NSDE operand.Ī number of optical systems (e.g.
