65-641 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 535nm
The 65-641 is a Bandpass Filter, specifically designed and manufactured by Edmund Optics. This filter is circular in shape, with a diameter of 12.5 mm and a thickness of 7.5 mm, making it suitable for a wide range of optical applications.
The filter is made from UVFS Mal-1965, a material known for its optical properties. It is designed to operate at a central wavelength of 535 nm, with a full width at half maximum (FWHM) of 10 nm. This makes it ideal for applications that require narrowband filtering around the specified wavelength.
The 65-641 features a cut-on wavelength of 530 nm and a cut-off wavelength of 540 nm. This means it allows light within this range to pass through while blocking other wavelengths. The cut-on and cut-off wavelengths are crucial specifications in determining the filter's performance in a given application.
The filter is coated on both the front and back sides with EDm 65-641, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, ensuring reliable operation in various conditions.
The filter's shape is that of a Thin Lens, which is beneficial in applications where minimal optical path deviation is required. This, coupled with its compact size and robust construction, makes the 65-641 a versatile and reliable choice for many optical systems.
