495FDC25 25 mm Dia. Bandpass Dichroic Filter 495nm
The 495FDC25 is a Dichroic Filter with a circular shape and a diameter of 25 mm. This filter is sourced from Knight Optical, a renowned vendor known for its high-quality optical elements. The filter is made of n-BK7 Schott material, a borosilicate glass known for its excellent optical properties and durability.
The filter's primary function is to allow light in the 495 nm wavelength range to pass through while blocking light at other wavelengths. This is achieved through a precise coating on both the front and back surfaces, labeled as 'kni 495fdc-0'. The cut-on wavelength is 465 nm, and the cut-off wavelength is 525 nm, providing a narrow bandpass for the specified wavelength.
The filter has a thickness of 1.1 mm, which is considered thin for an optical element of this type. This thinness, combined with its circular shape, makes it suitable for various applications, including imaging systems, spectroscopy, and beam shaping.
The 495FDC25 is currently in stock and available for immediate purchase. For more information, you can visit the vendor's website through the provided weblink.
