Description
x700-780nm NIR bandpass filters are designed to isolate selected near-infrared wavelengths while suppressing unwanted visible and out-of-band light. These filters are commonly used in optical testing, NIR imaging, machine vision, spectroscopy, fluorescence detection, biomedical sensing, plant analysis, LED illumination systems, and laboratory research.
This product group covers several commonly used near-infrared center wavelengths, including 700nm, 710nm, 730nm, 740nm, and 760nm. Each filter is optimized to transmit light near its specified wavelength while providing blocking outside the passband. Depending on the wavelength option, bandwidths range from approximately 30nm to 50nm, with blocking levels such as OD2-OD3 or OD3.
The 700-780nm range is useful for applications that require separation between deep red and near-infrared light. For example, 700nm and 710nm filters are often used near the red/NIR transition region, 730nm filters are suitable for optical testing and NIR illumination analysis, 740nm filters provide a wider 50nm passband with high transmission, and 760nm filters are often used for near-infrared detection and imaging systems.
Custom center wavelengths, bandwidths, blocking ranges, dimensions, substrate materials, coating designs, and mounted or unmounted formats are available upon request. Filters can be supplied in round, square, or rectangular shapes for integration into optical instruments, camera systems, LED modules, sensors, and laboratory setups.
