BDA Bandpass filters

For the documentation of UV fluorescent images a bandpass filter has to be attached in front of the camera lens. The filter has to be choosen in respect to the applied sample staining. The most commonly used filter has a transmission maximum of 590 nm and fits e.g. to ethidium bromide, OrioleTM, SYPRO® Orange and SYPRO® Ruby
staining. This filter is supplied as standard in BDA systems.

An alternative filter is available for fluorescent dyes with emission wavelengths between 500 and
580 nm, such as SYBR® Green, SYBR® Gold, SYBR® Safe and GelStar®.

Optimal results with every dye are always achieved with the respective dedicated filter. Nevertheless it is possible
to apply a bandpass filter with a wider bandpass which covers several dyes with different emission maxima. This might be helpful when a stand or a darkhood without filter wheel is used. Biometra offers such a bandpass filter with wide bandpass: filter BP590 / 200. It can be used together with a Biometra standard transilluminator UVstar as this comes with a high-grade filter for low background signal. To achieve an even more high-contrast image with the wide bandpass filter it is recommended to choose the Super Brilliant version of UVstar, one of the “UVstar plus“ transilluminators.
