Filters are optical components that attenuate light intensity, alter spectral composition, or limit vibration planes.  

Filters, commonly used as accessories in photochemical experiments, are made by depositing different film materials on glass or quartz substrates to achieve the desired filtering effect.

Bandpass filters refer to filters where the transmission band on the spectral characteristic curve is flanked by cutoff regions, allowing specific spectral wavelengths to pass through.  

Bandpass filters are abbreviated with "DT" at the beginning of their names, and there are 15 common models, including DT 350, DT 365, DT 380, DT 400, DT 405, DT 420, DT 435, DT 450, DT 475, DT 500, DT 520, DT 550, DT 600, DT 650, DT 700.  

If you need bandpass filters for specific spectral wavelengths, you can call 400-1161-365 for customized options.
