Enquire About This Product
Overview
The IS-MA series integrating spheres feature LISUN's patented A-Molding technology for a more perfectly round sphere and more accurate test results than traditional multi-piece assembled spheres. An expandable and adjustable holder base (bracket) accommodates diverse LED lamp types including streetlights, floodlights and tubes. A cross-laser alignment device ensures the luminaire's light-emitting surface is always precisely centred.
Available diameters: IS-0.3M (Ø0.3m), IS-0.5M (Ø0.5m), IS-1.0MA (Ø1.0m), IS-1.5MA (Ø1.5m), IS-1.75MA (Ø1.75m), IS-2.0MA (Ø2.0m), IS-2.5MA (Ø2.5m) and IS-3.0MA (Ø3.0m). Custom sizes available.
The holder base supports up to 20kg and can be installed on top or bottom with adjustable height. Four-wire connection to external power supply with max 5kW. BaSO4 coating meets CIE Pub. No.84 (1989): ρ(λ)≥0.96 (450–800nm), ρ(λ)≥0.92 (380–450nm).
Works with LISUN spectroradiometers for photometric, colorimetric and electrical parameter measurement. Flux testing range by size: IS-0.3M/0.5M: 0.001–1,999lm; IS-1.0MA: 0.1–199,990lm; IS-1.5MA/1.75MA: 0.1–1,999,900lm; IS-2.0MA: 0.1–1,999,900lm; IS-2.5MA/3.0MA: suited for CNAS accredited laboratory large luminaires.
