BP505 Cyan Bandpass Filter
Midwest Optical Systems (MidOpt)
BP505 are single substrate, hard-coated filters designed to match the output of most cyan LEDs. Coupled with the spectral sensitivity of most CCD/CMOS sensors in use today that also peak in this range, using this filter can result in images that are especially bright and very high in contrast. It is particularly useful for line ...

Did You know?

Optical Bandpass filters (BP Filters) are used in spectral photometry, clinical diagnostics, chemical analysis, colourimetry, astronomy, and numerous applications where spectral isolation is required. A Band-pass Filter transmits light only within a defined spectral band ranging from less than one to many nanometers wide and can be made by combining a Long pass and a Short Pass filter. Examples of bandpass filters are the Lyot filter and the Fabry-Pérot interferometer. The Dutch Open Telescope and Swedish Solar Telescope are examples where Lyot and Fabry-Pérot filters are being used.
