FSQ-OG515 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 515nm

The FSQ-OG515 is a 50.8 x 50.8 mm absorptive longpass filter, designed and manufactured by MKS/Newport. This filter is specifically engineered to transmit light at wavelengths above 515nm, while effectively blocking shorter wavelengths, making it an ideal component for various optical applications.

The filter boasts a robust rectangular base shape, with a generous width and height of 50.8mm each, providing ample surface area for light transmission. The thickness of the filter is 3mm, ensuring durability and stability in its setup. The filter's geometry is designed in a Thin Lens shape, which can contribute to minimal distortion and optimal light transmission.

The FSQ-OG515 features a specialized coating on both the front and back surfaces, identified as 'new og515'. This coating is crucial for the filter's functionality, as it facilitates the longpass characteristic of the filter. The cut-on wavelength is 515nm, indicating the point at which the filter begins to transmit light. The cut-off wavelength is 0nm, meaning the filter blocks all wavelengths shorter than 515nm.

This filter is available for purchase directly from the vendor's website, and the link provided is valid and indicates the filter is in stock, ready for immediate use. The FSQ-OG515 is a versatile and reliable optical component, suitable for a wide range of applications that require longpass filtering.
