65-119 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 830nm

The 65-119 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 830nm, making it suitable for a wide range of applications that require precise wavelength control.

The filter is constructed with a hard coating on both the front and back surfaces, denoted as 'edm 65-119'. This coating enhances the durability and longevity of the filter, making it resistant to wear and tear, and ensuring optimal performance over time.

The physical data of the filter is noteworthy, with a cut-on wavelength of 825nm and a cut-off wavelength of 835nm. This narrow bandwidth of 10nm, combined with the central wavelength, is indicative of the filter's high selectivity and efficiency.

The filter's geometry is another key feature. It has a thickness of 3.5 mm, which is crucial for maintaining the filter's integrity and preventing distortions in the optical path. The circular shape of the filter, along with its thin lens design, further contributes to its ease of integration into various optical systems.
