OSRAM TL/10 1A PICO SPEKTRAL - Thallium spectral lamp 15 V, 1 A (PICO9, 15 W AC)
The OSRAM TL/10 1A PICO SPEKTRAL is a thallium spectral lamp designed for scientific and industrial use when monochromatic radiation or stable line spectra are required. It operates at 15 V and 1.0 A ( 15 W ) AC , with a PICO9 base and a compact design for integration into optical benches. It offers intense and stable irradiance in characteristic thallium lines, widely used for instrument calibration and verification (e.g., emissions near 535 nm in green and 377.6 nm in ultraviolet, according to specialized literature). Its design and materials ensure reproducibility and ease of mounting in PICO lampholders.
