LP470 Light Yellow Longpass Filter
Light Yellow Longpass Filter for machine-vision imaging — passes 480-1100nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
A LP470 filter passes most visible and near-IR wavelengths of light. Used with monochrome cameras to aid in increasing contrast and resolution by blocking UV and shorter deep blue wavelengths. To achieve a similar effect while also blocking longer wavelengths including the near infrared, see our BP505 filter transmitting longer wavelengths often leads to decreased contrast in many LED-illuminated imaging applications.
