65-227 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 632nm

The 65-227 is a Bandpass Filter with a 50 mm diameter and a thickness of 3.5 mm, specifically designed for use with a central wavelength of 632 nm. This filter is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The Bandpass Filter is a type of optical filter that allows light within a certain range of wavelengths to pass through while blocking out other wavelengths. In this case, the 65-227 Filter is designed to pass light with wavelengths between 627 nm and 637 nm, making it ideal for applications that require precise wavelength selection.

The filter features hard coating on both the front and back surfaces, identified by the coating code "edm 65-105". This hard coating enhances the durability and longevity of the filter, making it resistant to scratches and other forms of damage.

The filter's geometry is defined by its diameter and thickness. With a diameter of 50 mm, it is suitable for use in a wide range of optical systems. The thickness of 3.5 mm contributes to the filter's overall robustness and stability.

The filter's physical data includes the cut-on wavelength at 627 nm and the cut-off wavelength at 637 nm, as well as the central wavelength at 632 nm. This information is crucial for selecting the right filter for your specific application.
