 Features  


HM series

  • Goniophotometric measurement for LED luminaries up to 2,400mm

  • Spectral distribution at each angle by controlling two-axis goniophotometer automatically to obtain total luminous flux with zonal spherical function

  • Goniophotometric measurement for large displays

  • Wide dynamic range with brand-new detector

  • Complying with IESNA LM-75 and CIE121

  • Usable for both Type B and Type C

  • Goniophotometric measurement at both UV and NIR region(spectral radiant flux calculation available)



FM series

  • Accommodates max. 2,400mm fluorescent tube

  • Has self absorption correction function
