65-147 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 488nm
The 65-147 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. Sourced from Edmund Optics, this filter features a 25 mm diameter and a thickness of 3.5 mm, making it suitable for a wide range of applications.
The filter is designed to transmit light at a central wavelength (CWL) of 488 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity makes it ideal for applications that require precise wavelength selection, such as fluorescence microscopy or laser spectroscopy.
The 65-147 filter is hard coated on both sides with EDM 65-086, a proprietary coating developed by Edmund Optics. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance even under demanding conditions.
The filter's geometry is defined by a circular shape, a common choice in optical systems due to its ease of alignment and integration. The cut-on wavelength is 483 nm, and the cut-off wavelength is 493 nm, providing a sharp roll-off on either side of the transmission band.
