86-945 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 825nm

The 86-945 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 825nm, 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 86-945'. This coating enhances the filter's durability and resistance to wear and tear, ensuring long-lasting performance. The filter's thickness is 3.5 mm, providing sufficient structural integrity for most applications.

The 86-945 features a Cut-On wavelength of 800nm and a Cut-Off wavelength of 850nm, as indicated in its physical data. This means that it allows light within the 800-850nm range to pass through while blocking other wavelengths. The Cut-On and Cut-Off wavelengths are crucial specifications in bandpass filters, as they determine the filter's passband.

This filter is of the Circular shape and has a Base Shape of Thin Lens. The Circular shape ensures easy integration into various optical systems, while the Thin Lens Base Shape allows for minimal optical aberrations.
