65-113 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 690nm

The 65-113 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 690nm, making it ideal for applications that require precise wavelength selection.

The filter boasts a hard coating on both the front and back surfaces, denoted as 'edm 65-113'. This coating enhances the filter's durability, making it resistant to scratches and other forms of damage, thereby ensuring longevity and reliable performance.

The 65-113 filter has a thickness of 3.5 mm, which is a significant factor in determining its optical performance. It features a cut-on wavelength of 685nm and a cut-off wavelength of 695nm, providing a narrow bandwidth that aids in the rejection of unwanted wavelengths.

The filter's geometry is defined by its circular shape and a diameter of 12.5 mm. This size is commonly used in various optical systems, ensuring compatibility and ease of integration.

The filter is made from UVFS Mal-1965 material, a choice that is informed by its specific optical properties. This material, in combination with the filter's design, ensures high transmission at the desired wavelength and effective blocking of unwanted light.
