67-746 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 280nm

The 67-746 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its circular shape, with a diameter of 12.5 mm, and a thickness of 3.5 mm, making it suitable for a wide range of optical applications.

The filter is constructed with a unique material ID, UVFS MAL-1965, which is specifically designed to handle ultraviolet light at a wavelength of 280nm. The physical data of the filter includes a cut-on wavelength of 275nm and a cut-off wavelength of 285nm, with a center wavelength (CWL) of 280nm. This precise wavelength control ensures optimal performance in specific UV applications.

The 67-746 filter features a thin lens shape, which is beneficial for applications where space is a constraint. The filter is coated on both the front and back surfaces with ED67-746, a specialized coating that enhances its performance and durability.

The filter is currently in stock and can be purchased directly from the Edmund Optics website, with the catalog number 67-746. The link to the product page is provided in the item data for your convenience.
