The Halo DB-20 is a high performance double beam spectrophotometer suitable for many analytical applications where a higher level of accuracy is required.Genuine Double Beam OpticsTrue double beam optics ensure concurrent measurement of the sample and reference for improved stability, accuracy and reproducibility. The light beam is split in two using a half mirror so that one beam passes through the sample side whilst the other passes through the reference side. Both beams are then measured on individual detectors. The reference side beam also acts to stabilize photometric values in a similar manner to the ratio beam principle.

The Halo RB-10 is a ratio beam spectrophotometer with an extensive array of built in functions for versatility and suitability to many analytical and biological applications. The ratio beam optics impart greater accuracy and reproducibility than the conventional, single beam optics.Ratio Beam Optics The absorbance signal in conventional single beam instruments can destabilize even during simple applications thus resulting in data inaccuracy. By contrast, ratio beam optics compensate and stabilize any signal fluctuations to increase accuracy and reliability even over prolonged usage such as in time course and kinetic measurements. The ratio beam principle involves splitting the beam generated by the light source by a half mirror. One of the split beams passes through the sample and is quantified by a detector whereas the other split beam which is representative of the absorbance signal is measured by an independent detector to obtain a signal reference. The ratio of the values from both detectors is then calculated to detect and compensate for any aberration in the energy of the light source or a temporal change of the optical elements and produce the highly stable photometric values. Spectral Features Boasting a 4 nm spectral bandpass the Halo RB-10 offers superior spectra and peak resolution. Other specifications include an impressive wavelength accuracy of ±0.5nm, noise level 0.0005Abs (500nm) and stray light ≤0.05% (220nm NaI, 340nm NaNO2).Built-in and Diverse Range of Measurement Modes Photometry Mode:Perform quantitative analyses in either absorbance or transmittance modes.
