65-222 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 580nm

The 65-222 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 580nm, making it suitable for applications that require precise wavelength selection within this range.

The filter is constructed with a hard coating on both the front and back surfaces, identified as 'edm 65-100'. This coating enhances the durability of the filter, providing resistance to wear and tear, and ensuring longevity in its performance. The filter's thickness is 3.5 mm, and it features a circular shape, which is a common design for optical components due to its ease of integration into various systems.

The 65-222 filter is a Thin Lens type, which implies that it has a very small focal length compared to its diameter. This feature is beneficial in applications where a wide field of view is required. The filter's cut-on wavelength is 575nm, and the cut-off wavelength is 585nm, providing a narrow bandwidth of 10nm. This characteristic is crucial in applications where stray light or out-of-band radiation needs to be minimized.

The filter's physical data, including the cut-on, cut-off, and central wavelength, are all precisely controlled during the manufacturing process. This ensures that the filter performs optimally in its intended application. The filter is currently in stock and available for immediate purchase, as indicated by its weblink status.
