In its standalone mode, the compact BTS256-LED meter is designed for the convenient measurement of luminous flux, spectrum, color, and color rendering index of single LEDs. A key feature is the conical measurement port at the entry of the internal integrating sphere which enables the measurement of onboard LEDs. The bayonet connector used to attach the conical adapter makes it possible to combine the BTS256-LED with other accessory components. Gigahertz-Optik offers different accessories as part of the BTS256-LED Plus Concept which greatly extends the measurement capabilities of the BTS256-LED.
Enhancement of the BTS256-LED using the ISD-50HF-V01 or ISD-50HF-V02 integrating sphere
The 50 cm diameter ISD-50HF-V01 integrating sphere makes it possible to measure the luminous flux, spectrum, color, and color rendering index of extra-large LED lamps with 2pi and 4pi radiation characteristics. One half of the sphere can be opened in order to fix LED lamps onto the sample holder at the center of the sphere. The height of the sample holder can be adjusted.
The ISD-50HF-V02 is offered as an alternative and has an additional 2pi measurement port with a 127 mm diameter. This remains closed whenever it is not in use.
Both variants are equipped with an auxiliary lamp. The BTS256-LED can still be used to measure single, onboard LEDs. A bayonet adapter enables connection of the device onto the ISD-50HF integrating sphere.
