Choosing a Raman longpass edge filter should start with two numbers: the excitation laser wavelength and the lowest Stokes Raman shift you need to measure. The nominal cut-on wavelength alone is not enough. A useful Raman edge filter must simultaneously provide strong rejection at the…
A beamsplitter does not treat s- and p-polarized light the same way. At any angle other than normal incidence, the reflectance of a surface or coating is higher for s-polarization than for p-polarization, and the difference grows with the angle of incidence. At 45°, the…
Internal transmittance falls exponentially with path length, τ = exp(−αd); doubling thickness squares τ, and the loss doubles only while absorption is weak. Uncoated glass at n = 1.5 transmits at most 92.3% at normal incidence (calculated); that gap is reflection, not absorption. A transmission…

Jiite, together with Anshan and Nanjing branches, gathered here (booths 7B31 in Hall 7 and 1A73…
A fluorescence filter set is three components engineered as one spectral system: an excitation filter (exciter) that cleans up the illumination, a dichroic beamsplitter that separates excitation from emission, and an emission filter (emitter) that passes fluorescence and rejects everything else. Fluorescence filter set design…
The practical difference in an F-theta lens vs standard focusing lens comparison is the job each optic is designed to perform. A standard focusing lens is normally chosen to form a good focus at one on-axis location, or within a limited field defined by its…
