36-640 25.4 mm Dia. Hard Coated Ultra Narrow Bandpass Filter; t=2mm 532nm

The 36-640 is a high-performance Bandpass Filter, offered by the renowned optical component vendor, Edmund Optics. This filter, with a diameter of 25.4 mm and a thickness of 2 mm, is designed to transmit light at a central wavelength (CWL) of 532 nm, making it ideal for applications that require narrowband filtering around this wavelength.

The filter is made from borofloat33, a borosilicate glass known for its excellent optical properties and durability. The 36-640 features hard coatings on both the front and back surfaces, denoted as 'edm 36-640', which enhances the filter's resistance to scratches and environmental stress, ensuring longevity and reliability in various operating conditions.

The 36-640 boasts a cut-on wavelength of 531.4 nm and a cut-off wavelength of 532.6 nm, providing a narrow passband around the CWL. This characteristic is crucial in applications where stray light or out-of-band signals need to be minimized, such as laser systems, spectroscopy, and fluorescence microscopy.

The filter's geometry is designed in a Thin Lens shape, which can be beneficial in applications where minimal optical path deviation is required. This, coupled with its circular form factor, makes the 36-640 a versatile and efficient solution for narrowband filtering.
