65-129 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 340nm

The 65-129 is a Bandpass Filter with a diameter of 25 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is designed to allow light transmission within a specific range of wavelengths while blocking out other wavelengths, making it ideal for applications requiring narrow-band light.

The filter's central wavelength (CWL) is 340nm, which is the wavelength at which the filter has its maximum transmittance. The cut-on wavelength is 335nm, and the cut-off wavelength is 345nm, indicating the range of wavelengths that the filter effectively passes. This makes it suitable for applications that require precise wavelength selection.

The filter is constructed with a thickness of 3.5 mm, providing durability and stability. It features a hard coating on both the front and back surfaces, enhancing its resistance to wear and environmental factors, thereby extending its lifespan.

The 65-129 filter is designed in a circular shape, a common form factor for optical components due to its ease of integration into various systems. It is also shaped as a thin lens, suggesting its potential use in focusing or collimating light.
