65-070 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 394nm

The 65-070 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 394nm, 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 65-070'. This coating enhances the filter's durability, making it resistant to scratches and other forms of wear and tear. The geometry of the filter includes a thickness of 3.5 mm, which contributes to its overall robustness and stability.

The 65-070 filter features a Cut-On wavelength of 389nm and a Cut-Off wavelength of 399nm, as indicated in its physical data. This wavelength range is further narrowed down by the Central Wavelength (CWL) of 394nm, ensuring a high level of wavelength specificity.

The filter is designed in a Thin Lens shape, which is a common choice for optical components due to its minimal impact on the overall optical path. This shape, combined with the filter's compact diameter, makes it a versatile choice for a wide range of optical systems.
