86-646 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 700nm

The 86-646 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable vendor, Edmund Optics. This filter is specifically designed for a central wavelength of 700nm, making it ideal for applications that require precise wavelength selection within this range.

The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 86-646'. This coating enhances the filter's durability and resistance to environmental factors, ensuring longevity and reliability in its performance.

The physical data of the filter includes a cut-on wavelength of 687.5nm and a cut-off wavelength of 712.5nm. This means the filter allows transmission of light within this specific range, effectively blocking out unwanted wavelengths. The cut-on and cut-off values are crucial in determining the filter's performance and suitability for specific applications.

The filter has a thickness of 3.5 mm and is shaped as a thin lens. This thickness, combined with the hard coating, ensures the filter maintains its shape and integrity, even under demanding conditions. The circular shape of the filter is a common and versatile design, suitable for a wide range of optical systems.

The filter is made from UVFS Mal-1965, a material known for its optical properties. This material, combined with the filter's specific design, makes the 86-646 an excellent choice for applications that require precise wavelength control and high-quality optical performance.
