What is typical application for 580nm bandpass filters?
A 580nm bandpass filter is an optical device that selectively transmits light centered at 580nm while blocking light at all other wavelengths. 580nm bandpass filters serve a wide range of applications, including bioanalysis, optical imaging, and industrial inspection. They excel in fluorescence microscopy of stained samples, flow cytometry, microplate readers for biochemical assays, plant optical research, machine vision systems for color and surface inspection, and portable fluorescence diagnostic devices for rapid in-vitro testing.
What are key parameters when choose for a suitable Bandpass Filter?
When selecting a Narrow Bandpass Filter, normally the following factors need to be taken into consideration：
- Central Wavelength (CWL)：CWL is one of key parameter to designate first, it refer to the central wavelength at stable high transmission rate passband.
- Peak or Average Transmittance: typically ≥90%, Higher transmittance might need Anti-reflective(AR) coating.
- Full width at half maximum (FWHM): FWHM refer to the interval between the two wavelength points where the transmittance rate reaches 50%.
- Blocking rate: usually in terms of optical density(OD), OD2-OD3 for standard and higher will be OD4-OD6 per requirement.
- Angle of Incidence (AOI): AOI need to be considered as Interference Filter is angle sensitive, 0° AOI by default, other AOI e.g. 30/45° need to be specified.
- Physical and environmental requirement: Substrate type, dimensions and thickness, surface quality, and environmental durability.
