Compact UV Absorption Sensor Eliminates Beam Splitters

The patent divides the optical path into separate segments for UV light and reference light, using distinct optical components for each wavelength range. This allows independent optimization of each optical path without requiring complex beam splitting mechanisms, thereby reducing overall system size while maintaining measurement precision.

The patent extracts and removes beam splitters from the optical system, replacing them with wavelength-specific optical components. This elimination of unnecessary components directly reduces system size and complexity while preserving the ability to measure both UV absorption and reference light intensities.

The patent replaces expensive beam splitters with more economical wavelength-specific optical components and detectors. This substitution uses cheaper, specialized components designed for specific wavelength ranges, reducing overall system cost while maintaining the capability to perform dual-wavelength measurements.

The patent changes the optical parameters by using components optimized for specific wavelength ranges rather than broadband components like beam splitters. This parameter-specific approach allows the use of more cost-effective, specialized optical elements that perform better at their designated wavelengths.

The patent segments the optical system into distinct UV and reference light paths, each with its own optimized components. This segmentation eliminates the need for complex beam splitting and combining mechanisms, simplifying the overall optical structure while maintaining ease of operation through modular design.

Instead of combining light paths using beam splitters, the patent inverts the approach by keeping light paths separate and using independent detection channels. This inverted architecture simplifies the optical structure by eliminating the complexity of beam combination while maintaining the ability to measure both wavelengths effectively.
