Description

BP324 Near-UV Bandpass Filter

Useful in UV imaging applications, BP324 filters have a broad spectral bandwidth in the UV while effectively blocking most visible and infrared light. Note that there is a slight deep red/near IR leak that peaks at about 720nm. Because this filter absorbs all unwanted visible and/or infrared light, it is not recommended for placement in front of intense (white) light sources.

  • Passes UV portions 320-380 nm and 280-320nm
  • Blocks < 280 nm
  • Configurations can also be supplied for mounting in front of UV LED light sources

The Benefits of Filters – One Filter, Works Twice as Hard

Single & Dual Bandpass Filters by MidOpt

  • MidOpt Dual Bandpass filters transmit two specific wavelength ranges while blocking unwanted light, eliminating the need for a second camera or costly filter switching mechanisms.
  • Dual and single band filters for NDVI imaging have been created with specific vegetative reflection bands and camera spectral response in mind. Most popular plant health indices can be accommodated. Even lower cost consumer cameras can be easily converted or modified for monitoring vegetation. In order to reduce weight, standard thickness is 1mm.
  • Dual Bandpass filters also allow use of color cameras for both day and night imaging, even in complete darkness. A broad visible pass band is designed to mimic that of the camera’s original IR blocking filter, while an infrared band is also provided to match popular infrared LED illuminator wavelengths. 735nm, 850nm and 940nm dual band filters are available.
  • Using a DB940 filter, commensurate IR lighting produces virtually no visible signature while daytime color rendition is uncompromised. Suitable applications include security surveillance, traffic monitoring, license plate recognition, 3D point cloud imaging and game tracking.
  • After the color camera’s internal IR blocking filter has been removed, dual or single band filters can be provided in threaded aluminum mounts, black Deirin slip-on filter mounts or in custom sizes and thicknesses for mounting between the lens and the sensor.
