For the science and tech folks out there - this 532nm narrow band optical filter is seriously precise equipment for specialized applications. The central wavelength is 532nm with a tolerance of ±5nm, and it has a narrow half bandwidth of just 20nm, meaning it's super selective about what light passes through. The peak transmittance is over 90%, so you're getting excellent light efficiency while maintaining that precise wavelength filtering. The filter itself is square shaped at 8.0 x 8.0 mm with a thickness of 0.7mm, making it compatible with various optical setups and equipment. The cut-off depth ensures that unwanted wavelengths are effectively blocked, giving you clean, accurate results for your specific applications. This type of filter is commonly used in biological inspection, fluorescence imaging, scientific research, laboratory applications, and various optical instruments where precise wavelength control is crucial. The mirror glass construction provides durability and consistent performance. Whether you're working in research, quality control, or specialized imaging, this filter delivers the accuracy and reliability you need. The 532nm wavelength is particularly useful in many scientific and industrial applications where specific green light filtering is required. The quality construction means it'll maintain its optical properties over time, providing consistent performance for your important work. It's one of those specialized components that might seem simple but makes a huge difference in the accuracy and quality of your optical systems and measurements. If you need precise wavelength control for your equipment or experiments, this narrow band filter delivers professional-grade performance in a compact, reliable package that gets the job done right every time.
