65-646 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 580nm

The 65-646 is a 12.5 mm diameter mounted bandpass interference filter, specifically designed with a central wavelength of 580nm and a full width at half maximum (FWHM) of 10nm. This filter is sourced from Edmund Optics, a renowned vendor in the optical industry, and is currently in stock with a valid weblink for easy access to additional information.

This filter is categorized as a bandpass filter, a type that allows only a specific range of wavelengths to pass through while blocking others. In this case, the 65-646 filter is designed to allow wavelengths around 580nm to pass while blocking wavelengths outside this range. This feature makes it ideal for applications that require the selection and isolation of specific wavelengths.

The filter is made of UVFS material with the Mal-1965 material ID. It has a circular base shape and a thickness of 7.5mm. The geometric specifications include a 12.5mm diameter, making it suitable for various optical systems.

The 65-646 filter features a thin lens shape and is coated on both the front and back surfaces with the EDM 65-646 coating. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission in the desired wavelength range.

The physical data of the filter includes a cut-on wavelength of 575nm and a cut-off wavelength of 585nm. These values represent the transition points where the filter starts and stops blocking wavelengths, respectively. The central wavelength (CWL) of the filter is 580nm, indicating the wavelength with the highest transmission.
