Narrowband Filters for Biochemistry Analyzers

Biochemical analyzer is a sophisticated instrument used to measure the metabolites present in biological samples such as blood or urine in clinical diagnosis, Biochemical analyzer determines biochemical indicators such as transaminases, hemoglobin, cholesterol, creatine kinase, and glucose. The working principle is based on the Lambert-Beer Law. Narrow bandpass filters offer high transmission within a narrow range of wavelengths centered around the center wavelength while blocking unwanted light. A monochromatic light beam is obtained through a filter (or light baffle). When the monochromatic light enters the liquid being tested, a portion of the light is absorbed by the measured liquid, and the remaining transmitted light is received by a photodetector and converted into an electrical signal. After appropriate conversion and preprocessing of this signal, referencing a standard curve allows the determination of the concentration of the measured liquid.

In biochemistry analyzers, narrowband filters serve as indispensable elements to facilitate the precise detection and quantification of biomolecules. Filtering out undesirable background signals and ambient noise, these filters enhance the signal-to-noise ratio, improving the accuracy and reliability of analytical measurements.

Shalom EO offers stock and custom Narrowband Filters for Biochemistry Analyzers. These filters utilize a cutting-edge hard coating technique, where the hard coatings are deposited on substrates consisting of colored glass bonded with BK7.  The standard Optical Density is ≥OD4, which blocks unwanted wavelengths with great rejection effectiveness, ensuring accurate, targeted analysis. Their 10nm+/-1nm Bandwidth enables sharp isolation of specific wavelengths, facilitating impeccable biochemical measurements. Trusted for precision and durability, Shalom EO's filters are essential for precise biochemistry assays in labs and research facilities, elevating your analysis capabilities. Besides the stock versions, other parameters such as center wavelength, bandwidth, and optical density can be tailored to match the spectral characteristics of target analytes, maximizing signal detection while minimizing background interference.
