Now available from ProDesign Lighting , the Beam Calculator is ideal for those who have ever needed to work out the beamspread for a fixture over a specific throw distance, or how big the gobo image will be on the cyc from a certain distance.
The ProDesign Lighting Beam Calculator is free to download and uses Microsoft Excel software. It is very simple to use by following the below steps:
- Measure or estimate the throw distance from the lens to the focus location and type in the result.
- Make a note of the beam angle of your preferred Selecon fixture and type in the angle.
- The resulting beam size is then displayed.
If the direct distance from the lens to the subject is unknown, the program can calculate the throw by the user inputting the horizontal and vertical measurement between the two points.
By altering the throw distance or beam angle, the best coverage for a specific application will be calculated.
