Orange Bandpass Filter.
Recommended for use with amber/orange LEDs and fluorescence imaging.
BP590 single substrate, hard-coated filters are recommended for use in systems that use amber or orange LED lighting. They are also very widely used in fluorescence imaging applications, particularly with certain inks and ethidium bromide, Qdot 605 and other similar stains.
As with all MidOpt bandpass filters, peak transmission is greater than 90%. Blocking of shorter AND longer wavelengths averages >99% when used in conjunction with any sensor that has a typical silicon response. This is particularly important in situations where infrared light may be present. Orange longpass filters have traditionally been recommended for these applications, but they offer no such IR?blocking and therefore contrast can suffer.
