65-679 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 410nm
The 65-679 is a 25 mm diameter, 7.5 mm thick Bandpass Interference Filter, specifically designed for use at a central wavelength (CWL) of 410nm. This filter, offered by Edmund Optics, is a crucial component in various optical systems, providing excellent selectivity and transmission characteristics.
The filter's bandpass properties are defined by its cut-on wavelength of 405nm and cut-off wavelength of 415nm. This narrow bandwidth allows for precise wavelength selection, making it ideal for applications where narrowband filtering is required. The filter's coating, both on the front and back surfaces, is identified as EDM 65-619, which contributes to its high performance.
The 65-679 filter is designed in a Thin Lens shape, which is beneficial for applications where space is a constraint. The circular geometry of the filter, with a diameter of 25mm, ensures easy integration into various optical systems.
The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. The catalog number, 65-679, can be used for easy reference and identification.
