Use BeamCalc to calculate the geometry and photometrics of spotlight beams. Position and direct three light sources (chosen from the included library) to determine lighting characteristics: elevation angle, beam and field pool width, illumination, shadow length.
Light sources and focus targets can be positioned numerically or graphically. Work in either meters/lux or feet/footcandles.
The source library contains over 100 fixtures including ETC Source Four, Strand SL, Selecon Pacific, Altman Shakespeare, Colortran, generic PAR64 and others. Future updates will bring many additional manufacturers and fixtures, both current and out-of-production.
BeamCalc is designed for use in architectural, display and entertainment lighting designs utilizing theatrical fixtures.
