Interference optical filter ZLY254

band-pass

The Fluorescence Bandpass Filters is selected and made to allow the fluorescence/emission light to pass through as much as possible at the imaging end, while completely blocking the excitation light to obtain the highest signal-to-noise ratio. Especially for the application of multiphoton excitation and total internal reflection microscopy, weak noise will also cause great interference to the imaging effect, so the requirement for signal-to-noise ratio is higher. Usually we look at the parameters of the Fluorescence Bandpass Filters we will look at the transmittance spectrum, but often the intensity of the fluorescence relative to the excitation light is very weak, and the selection of the filter needs to refer to the blocking depth spectrum -- OD value. The OD value can more intuitively reflect the light blocking characteristics of the filter. Zoolied offers a variety of Optical Filters, such as CCD Gel Imaging System Filters,Longpass Filters, Dichroic Filter, and Biochemical Analyzer Filters. ZOOLIED provides multiple anti-reflection coating options for the Ultraviolet (UV), visible, or Ir Filters and also provides uncoated Optical Glass Filters based on K9 optical glass and UV fused silica.
