65-633 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 492nm

The 65-633 is a 12.5 mm diameter, 7.5 mm thick Bandpass Interference Filter, specifically designed for use at a central wavelength (CWL) of 492nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock with a valid weblink for easy access to additional information.

The Bandpass Interference Filter is a type of optical filter that allows light within a specific range of wavelengths to pass through while blocking out other wavelengths. In this case, the 65-633 filter is designed to pass light with a wavelength of 492nm, making it ideal for applications that require precise wavelength selection.

The filter's physical data includes a cut-on wavelength of 487nm and a cut-off wavelength of 497nm. This means that it begins to transmit light at 487nm and stops transmitting at 497nm, effectively filtering out any wavelengths outside this range. The filter's coating, both on the front and back, is identified as 'edm 65-633', further ensuring its specificity to the 65-633 filter model.

The filter's geometry is defined by its 12.5 mm diameter and 7.5 mm thickness, making it suitable for use in a variety of optical systems. Its shape is described as a Thin Lens, indicating its potential use in focusing or collimating light.
