Below is the schematic for fluorescence imaging system. We can provide narrow-band filters, multi-channel filters, and dichroic mirrors inside. For fluorescence imaging applications, due to the extremely weak energy of fluorescence, xxx uses advanced ion sputtering coating equipment to achieve extremely narrow , extremely steep filter (bandwidth 3nm, transition zone 6nm), high transmittance and high cut-off depth (OD6) to ensure the accuracy of fluorescence signals.

Optical Products Inventory List

Omeda have rich experience in biomedical products,we do many projects with our clients and accumulated a lot of stock filter, the stock filters list can help you save a lot of money on sample cost.

Remark：In addition to common wavelengths, we warmly welcome you to customize specified wavelength, half-width, transmittance, and cut-off depth filter ; we are especially good at dual-wavelength and multi-wavelength bandpass filter .

Fig. 1. The laser that was separated into four narrow-spectrum excitation channels that travelled through clean-up filters, neutral density filters, and beam-expanding telescopes prior to being recombined. The combined excitation colors were passed through the microscope objective to illuminate a diffraction-limited volume within the sample. The fluorescence emission was collected by the objective, passed through an emission filter and a pinhole before being focused on the camera sensor. .
