20CGA-420 2 x 2 in Square Colored Glass Alternative Longpass Filter 420nm
The 20CGA-420 is a Longpass Filter from MKS/Newport, designed with a 2 x 2 in square shape and a thin lens form factor. This filter is part of the UVFS MAL-1965 material ID family, ensuring high-quality performance and durability.
The filter's primary function is to allow light with wavelengths longer than 420nm to pass through while blocking shorter wavelengths. This is particularly useful in various applications where the elimination of specific light spectrums is required. The cut-on wavelength is 420nm, and there is no specified cut-off wavelength, indicating that it blocks wavelengths shorter than 420nm.
The geometry of the 20CGA-420 includes a width of 50.8mm, a height of 50.8mm, and a thickness of 1.1mm. This compact size and thin profile make it an ideal solution for integration into various optical systems.
The coating on both the front and back surfaces of the filter is 'new 20cga-420'. This coating enhances the filter's performance and longevity, ensuring reliable operation in its intended application.
The filter is currently in stock and can be purchased directly from the vendor's website. For more information, please refer to the provided weblink.
