680DF15 12.7 mm Dia. Protected Coating; Bandpass Filter Protected Coating

The 680DF15 is a Bandpass Filter, a type of optical element designed to transmit light within a specific range of wavelengths while blocking other wavelengths. This particular model, sourced from the reputable vendor Omega Optical, boasts a catalog number of 680DF15 and is available for purchase through their official website.

The filter has a circular shape with a diameter of 12.7 mm and a thickness of 5.08 mm, making it suitable for a wide range of optical applications. It is constructed from UVFS MAL-1965, a material known for its optical properties and durability.

The 680DF15 has a cut-on wavelength of 672.5 nm and a cut-off wavelength of 687.5 nm, with a central wavelength (CWL) of 680 nm. This means it allows the passage of light in the red part of the spectrum, specifically around the 680 nm mark, while blocking light of other wavelengths.

The filter features a protected coating on both the front and back surfaces, identified as 'ome 680df15'. This coating enhances the filter's durability and performance, providing an additional layer of protection against environmental factors and potential damage during handling or use.

The filter's shape is described as a Thin Lens, indicating its potential use in focusing or diverging light beams. This versatile filter is a valuable addition to any optical setup requiring wavelength-specific light transmission.
