We will introduce various filters used in fluorescence analysis and Raman spectroscopy measurement instruments.
Fluorescence analysis: This is a method of analysis that utilizes the property of fluorescent substances to emit fluorescence when excited light is irradiated onto them. Raman spectroscopy: This is an analytical method that uses the Raman effect and has become widely used in many fields as a local analysis method. The measuring instruments used for these spectroscopic analyses handle very weak signals, and high performance is required for the optical elements used.

basic information
【Usage Examples】 ◯ Bandpass Filter A filter designed to transmit the wavelength of the excitation light while minimizing the attenuation of unnecessary light other than the excitation light. Depending on the measurement system, a wide range of attenuation may also be required. ◯ Dichroic Mirror Mainly used at an incident angle of 45 degrees, it is used to irradiate the excitation light onto the sample and to allow the passage of fluorescence and Raman scattered light. ◯ Edge Filter A filter that transmits fluorescence and Raman scattered light from the sample while blocking excitation light and other components contained in the light from the sample, requiring a steep rise characteristic. ● For more details, please contact us.
