HB600 Optical Red Longpass Filter | 600nm Cut-off Filter Glass
Industrial-Grade Precision | High Contrast | Equivalent to RG610/R-60
YOUJIA OPTICAL’s HB600 Longpass Filter is engineered for high-performance optical systems requiring a sharp cut-off at 600nm. By absorbing wavelengths below 580nm and providing high transmission (>90%) in the red and near-infrared (NIR) spectrum, it is the ideal component for machine vision, fluorescence analysis, and laser applications.
