Transmittance curve, wavelength 520nm, fluorescence detection element detection filter
Fluorescence detection bandpass filter, mainly used for fluorescence microscopy, fluorescence qualitative instruments.
Fluorescent filters are widely used in the neighborhood of biochemical analysis. Fluorescent filters generally contain two types, namely excitation filters and emission filters.
Exciting Filter (Exciting Filter, Excitation Filter): In a fluorescence microscope, only the filter that excites the wavelength at which fluorescence can pass. There is also a direct use of laser light as excitation light.
Emitting Filter (Emission Filter, Barrier Filter, Emitter): Select and transmit the fluorescence emitted by the sample, and other ranges of light are cut off. The wavelength of the emitted light is longer than the wavelength of the excitation light. A band pass filter or a long pass filter can be selected as the emission filter.
The 520 nm fluorescent filter belongs to the emission fluorescent filter.

called the phase condition. The amplitude condition is a function of the two subsystems. The phase condition can be satisfied by adjusting the thickness of the spacer layer. The amplitude condition can, using a method devised by Musset and Thelen, be satisfied for all wavelengths, but it is difficult to satisfy the phase condition except at a limited number of discrete wavelengths. At other wavelengths, the performance departs from ideal to a varying degree. The transmittance and reflectance of a multilayer remain constant when the optical admittances are all multiplied by a constant factor or when they are all replaced by their reciprocals, in both cases keeping the optical thick- nesses constant. These properties can readily be demonstrated from the structure of the characteristic matrices . They enable the design of pairs of substructures having identical reflectance so that only the phase condi- tion need be satisfied for perfect antireflection. We can, following Musset and Thelen, imagine a multilayer consisting of two subsections a and b, as shown in Figure 4.15, with a medium of admittance yi in between. At this stage, we put no restrictions on this medium in terms either of refractive index or of thickness but, as we shall see, they will become defined at a later stage. Subsection a is bounded by ym on one side and yi on the other, while b is bounded in the same way by yi and y0. We can now apply the appropriate rules for ensuring that the amplitude condition is satisfied.China Fluorescent Detection Bandpass Filter manufacturers
