33-909 12.5 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 620nm

The 33-909 is a Bandpass Filter, specifically designed for Fluorescence applications, sourced from the reputable optical vendor, Edmund Optics. This filter, with a diameter of 12.5 mm, is an excellent choice for those seeking high-quality, precise optical components.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths. The 33-909 is designed to pass light at a central wavelength (CWL) of 620nm, with a bandwidth of 56nm. This makes it ideal for applications that require the isolation of light in this wavelength range.

The filter's physical dimensions are also noteworthy. It has a thickness of 2mm, which contributes to its durability and stability in optical systems. The cut-on wavelength is 592nm, and the cut-off wavelength is 648nm, further enhancing its ability to isolate the desired wavelength.

The 33-909 features hard coating on both the front and back surfaces, denoted as 'edm 33-909'. This coating enhances the filter's durability and resistance to wear, making it suitable for use in various environments.

The filter's shape is defined as a Thin Lens, which is a common form factor in optical systems. This shape, combined with its other features, makes the 33-909 a versatile and reliable choice for Fluorescence applications.
