89-826 36 mm Dia. Mounted Dark Red Machine Vision Imaging Filter; t=1.75 mm 660nm

The 89-826 is a Dark Red Machine Vision Imaging Filter, specifically designed for use in machine vision applications. Sourced from the reputable vendor Edmund Optics, this filter boasts a catalog number of 89-826 and is readily available for purchase.

This filter is a Bandpass Filter, a type that allows only a specific range of wavelengths to pass through while blocking others. The 89-826 is designed to permit wavelengths around 660nm, making it ideal for applications that require the isolation of this particular light spectrum.

The filter is circular in shape, with a diameter of 36mm, providing a substantial surface area for light to pass through. It has a thickness of 1.75mm, offering a balance between durability and light transmission.

The 89-826 features a UVFS MAL-1965 material ID, ensuring high-quality performance and reliability. Its physical data includes a cut-on wavelength of 627nm and a cut-off wavelength of 693nm, further emphasizing its bandpass capabilities.

The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 89-824, a coating that likely enhances the filter's performance and longevity.

The filter's shape is described as Thin Lens, suggesting it may have lens-like properties or be used in conjunction with lenses in optical systems. This filter is a valuable addition to any machine vision setup, offering precise wavelength selection and high-quality construction.
