Energy Matching Biochemical Filters from Shape Optics Technologies Pte Ltd are engineered for high-accuracy biochemical and spectroscopic measurements. By precisely matching the spectral energy of the illumination source, detection channel, and sensor, these filters deliver excellent measurement accuracy, repeatability, and consistency.
This energy-matching approach is critical in complex biochemical assays where overlapping spectra can introduce errors. SOT’s advanced multilayer dielectric coatings ensure high cut-off depth, minimal inter-channel interference, and stable performance, making these filters ideal for biochemical analyzers, enzyme assays, and clinical diagnostic instruments.
