65-109 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 650nm

The 65-109 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 650nm, 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 65-109'. 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 65-109 features a Cut-On wavelength of 645nm and a Cut-Off wavelength of 655nm, as indicated by its physical data. This wavelength range is further specified by the Cut-On and Cut-Off values, which are crucial for determining the filter's performance in various applications. The Center Wavelength (CWL) of the filter is 650nm, indicating the central point of the filter's passband.

This filter is designed in a Circular shape, with a Base Shape of Thin Lens. The circular shape is universally applicable across various optical systems, while the Thin Lens Base Shape ensures minimal optical aberrations. The filter is made from UVFS Mal-1965 material, further enhancing its optical performance.
