The 65-701 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 535nm, with a full width at half maximum (FWHM) of 10nm, making it ideal for applications that require narrowband transmission. The filter features a thin lens shape, with a thickness of 7.5mm, providing excellent optical performance and minimal distortion.
The filter is constructed with a UVFS MAL-1965 material ID, ensuring high-quality performance and durability. It is coated on both the front and back with EDM 65-641, a traditional coating that enhances its optical properties and protects it from environmental factors. The cut-on wavelength is 530nm, and the cut-off wavelength is 540nm, providing a sharp and precise transmission band.
This filter is available in stock and can be purchased directly from the Edmund Optics website. It is a versatile and reliable option for various applications, including biomedical imaging, fluorescence microscopy, and other scientific research where narrowband transmission is required.
