As a result, both small and large particles can be measured at the same time - continuously. Heuer, M., Leschonski, K., Results Obtained with a New Instrument for the Measurement of Particle Size Distributions from Diffraction Patterns, Part. It eliminates the need to have multiple lasers and switching between different light sources during the measurement. A 532 nm green diode-pumped solid-state laser (DPSSL) is used to increase the intensity of the scattered light produced by small particles for better sensitivity. The particles must also flow in a narrow stream due to focal length tolerances.ĭLOIOS places the sample cell between two Fourier lenses, whereby the second lens overcomes the limitation of conventional Fourier optics to allow a wide angle of measurement from 0.02 to 165°. However, this presents a drawback where there are fewer detector channels available on the forward detector, which leads to lower resolution and sensitivity to differentiate larger sized particles. Reverse Fourier optics produce a convergent incident beam that allows the instrument to capture high angles of scattered light. However, it is unable to detect the high angles of scatter produced by smaller particles. The Bettersizer S3 Plus features a patented optical arrangement called Dual Lens & Oblique Incidence Optical System (DLOIOS).Ĭonventional Fourier optics offer high resolution and precision. Unique optical arrangement for wide measurable size range
