Request InfoDelta Optical Thin Film A/SDelta Optical Thin Film has introduced new advanced excitation and emission bandpass optical filters for fluorescence spectroscopy/microscopy that enable more compact and lower cost fluorometers to be built. Traditionally, a fluorometer requires three optical filters – an excitation filter, a dichroic beamsplitter and an emission filter – in order to block out-of-band emission efficiently. However, with the new bandpass filters from Delta Optical Thin Film with typical pass band transmission of more than 95% and very high out-of-band blocking of OD6, the dichroic filter can...See full productRelated content from Photonics MediaPRODUCTSPromoted Content August 2023 IssueNotch FiltersNotch filters eliminate or block a range of wavelengths while transmitting both shorter and longer wavelengths outside of the blocked region.
