Wavelength range: Lambda 650 is 190–900nm, Lambda 850 is 175–900nm, Lambda 900 is 175–3300nm; the entire instrument and optical system utilize aerospace technology hardware: the entire optical system employs holographic grating coated with SiO2 (1440 lines/mm for UV/Visible, 360 lines/mm for near-infrared); it uses an advanced four-segment fan-shaped signal collection chopper, ensuring accurate signals for both the sample and reference during each measurement (during chopper operation, signals from the sample and reference are calibrated separately by their respective black zone signals, with high wavelength accuracy: 0.08nm in the UV/Visible range);

It features a pre-calibrated and automatically switchable tungsten lamp and deuterium lamp; high-sensitivity photomultiplier tubes are used in the entire UV/Visible range; a large sample compartment allows for various accessories and adjustments to the optical path, with many optional accessories (such as integrating spheres, fixed/variable angle relative/mirror reflection accessories, etc.), providing good stability, flat baseline, and low stray light. The instrument is extremely stable and durable. Wide linear range: 8A; multiple software options available: UV Winlab operating software package (standard configuration, including enzyme kinetics KinLab and biochemical methods BioLab), ASSP software package (including modules for colorimetry, filters, architectural glass, protective glass, mathematical operations, and databases, etc.).
