This filter is characterized by its circular shape, with a diameter of 42 mm and a thickness of 1.75 mm. It is constructed from UVFS MAL-1965 material, a common choice for optical filters due to its durability and optical properties. The filter's primary function is to allow light with a wavelength of 633 nm to pass through while blocking other wavelengths.

The 89-818 features physical data that includes a cut-on wavelength of 598 nm and a cut-off wavelength of 668 nm. The central wavelength (CWL) is 633 nm, indicating the peak transmission wavelength for this filter. This makes it ideal for applications that require precise wavelength selection, such as fluorescence microscopy or multispectral imaging.

The filter is coated on both the front and back with EDM 89-814, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, ensuring accurate and consistent wavelength selection over time.

The 89-818 filter is designed in a thin lens shape, allowing it to be easily integrated into various optical systems. Its light red color and machine vision application make it a unique and valuable addition to any optical component library.
