39-348 25 mm Dia. Hard Coated OD 4.0 5nm Bandpass Filter; t=3.5 mm 405nm
The 39-348 is a 25 mm diameter Bandpass Filter, specifically designed for use with a central wavelength (CWL) of 405nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website. The filter features a hard coating on both the front and back surfaces, ensuring durability and longevity.
The filter's geometry is defined by a diameter of 25mm and a thickness of 3.5mm. This robust construction allows for efficient integration into various optical systems. The physical data of the filter includes a cut-on wavelength of 402.5nm and a cut-off wavelength of 407.5nm, with the CWL falling neatly within this range.
The coating on the filter is a broadband AR coating, specifically the EDM 39-330. This coating is applied to both the front and back surfaces, ensuring minimal reflection and maximizing transmission. The filter's shape is that of a thin lens, further enhancing its versatility and utility in optical systems.
