DEscRIPTION:

The Beckman DU-650 is a full-featured scanning spectrophotometer with micro-focused beam technology provides precise and accurate results for samples as small as 5uL.

The micro-focused beam delivers the full energy of the beam to the microsample, unlike standard beams, which can lose as much as 80% of their energy when applied to a microvolume sample.

Wavelength Range: 190 to 1100 nm.

Wavelength Setability: 0.1 nm increments.

Wavelength Accuracy: +/-0.2 nm (at D2 peak 656.1 nm).

Wavelength Repeatability: +/-0.1 (at D2 peak 656.1 nm).

Spectral Bandwidth: <=1.8 nm.

Photometric Readout: -0.300 to 3.000 A or 0.0 to 200.0 %T.

Photometric Accuracy: +?-0.005 A (at 1A with NIST 930D solid filter at 546 nm).

Stray Light: <0.05 %T (using NaI at 220 nm per ASTM E387-84).

RMS Noise: <0.0002 A RMS (OA, average readings at 500 nm).

Scanning Speeds: 120, 240, 600, 1200, 2400 nm/minute
