LP830 Near-IR Longpass Filter
Near-IR Longpass Filter for machine-vision imaging — passes 845-1100nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
LP830 is suggested for use with infrared LED lighting emitting at 880nm or 850nm when it is also desirable to transmit other longer infrared wavelengths as well. Otherwise we recommend our BP880 or BP850 filters not only for their longer wavelength blocking, but their overall higher peak transmissions.
