65-223 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 589nm

The 65-223 is a Bandpass Filter with a diameter of 50 mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed for a central wavelength of 589 nm, making it ideal for applications that require precise filtering within this spectrum.

The filter boasts a hard coating on both the front and back surfaces, identified as 'edm 65-101'. This coating enhances the filter's durability and resistance to wear and tear, making it suitable for use in various environments. The filter's thickness is 3.5 mm, providing sufficient structural integrity while maintaining a low profile.

The 65-223 features a Cut-On wavelength of 584 nm and a Cut-Off wavelength of 594 nm, ensuring a tight 10 nm bandpass. This characteristic is crucial in applications where narrowband filtering is required, such as fluorescence microscopy, spectroscopy, or any other application that necessitates precise wavelength selection.

The filter's geometry is defined by its circular shape and 50 mm diameter, making it compatible with a wide range of optical systems. The physical data, including the Cut-On, Cut-Off, and Central Wavelength, are all carefully controlled during the manufacturing process to ensure high-quality performance.
