BTS256-LED-DA Diffuser Window
Available from Gigahertz-Optik
An optional diffuser is available for the BTS256-LED tester that allows it to measure light intensity like a luxmeter but with all color quantities and light spectrum included. The diffuser can be interchanged with the supplied cone adapter for dual purpose (lumens and lux) use. This option allows photometric, colorimetric and spectral analysis of any type of larger area light sources like LED arrays and fixtures without the need for an integrating sphere.
