The BTS256-LED light meter The compact BTS256-LED meter is designed to measure the luminous flux, spectrum, color, and color rendering index of LEDs. One of its key features is the conical measurement port at the entry of the integrating sphere for measurement of individual onboard LEDs. The conical adapter is attached using a bayonet connector which makes it possible to use the BTS256-LED with other entrance optic options. Gigahertz-Optik also offers different accessories as part of the BTS256-LED Plus Concept with which the capabilities of the BTS256-LED can be enhanced. Enhancement of the BTS256-LED using the diffusor window The addition of the BTS256-LED-DA diffusor window to the BTS256-LED makes it possible to use the device for illuminance measurements. It provides the required cosine correction over a +/- 30o degree field of view and is therefore only recommended for measurement of directional lamps. Illuminance measurement of extended lighting systems and street lights should be performed using Gigahertz-Optik’s MSC15 and BTS256-EF. The BTS256-LED-DA diffusor window is also necessary when the BTS256-LED is to be combined with the GB-GD-360-R40-2 goniometer to measure the luminous intensity radiance distribution.
