65-078 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 442nm
The 65-078 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 a central wavelength (CWL) of 442nm, making it ideal for applications that require narrowband transmission at this wavelength.
The filter is hard coated on both sides with the front and back coatings designated as 'edm 65-078'. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time.
The physical data of the filter includes a cut-on wavelength of 437nm and a cut-off wavelength of 447nm. This 10nm bandpass ensures a high level of transmission for the specified wavelength while effectively blocking out unwanted light outside this range.
The filter has a thickness of 3.5 mm and is shaped as a thin lens. This geometry, combined with its compact diameter, makes it suitable for integration into various optical systems where space is a constraint.
According to the vendor's information, the filter is currently in stock and can be purchased directly from the Edmund Optics website via the provided weblink.
