84-641 12.5 mm Dia. Traditional Coated OD 2.0 Shortpass Filter; t=1.5mm 1250nm

The 84-641 Shortpass Filter, sourced from Edmund Optics, is a circular filter designed with a diameter of 12.5 mm and a thickness of 1.5 mm. This filter is specifically designed for use in optical systems that require the removal of infrared light with wavelengths longer than 1250 nm.

The filter features a traditional coating on both the front and back surfaces, identified as 'edm 84-641'. This coating is designed to enhance the filter's performance and durability. The filter's geometry is shaped as a thin lens, which is ideal for applications where minimal thickness is required.

The 84-641 filter is a Shortpass Filter, a type of optical filter that allows short-wavelength light to pass through while blocking longer wavelengths. In this case, the cut-off wavelength is 1250 nm, meaning it blocks all light with wavelengths longer than this value. The cut-on wavelength is 0 nm, indicating that it allows all wavelengths of light shorter than this value to pass through.

This filter is available for purchase directly from the vendor, Edmund Optics, and is currently in stock.
