FSQ-OG550 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 550nm
The FSQ-OG550 is a high-quality absorptive longpass filter, designed and manufactured by MKS/Newport. This filter is specifically engineered for applications that require precise wavelength selection, making it an ideal choice for various optical systems.
The filter boasts a rectangular shape, with a width and height of 50.8 mm each, providing a substantial surface area for efficient light transmission. It has a thickness of 3 mm, ensuring durability and rigidity. The FSQ-OG550 is cut on at 550 nm, meaning it starts absorbing light at this wavelength, and it has a cut off of 0 nm, indicating that it allows all wavelengths shorter than 550 nm to pass through.
The filter's coating is another notable feature. Both the front and back surfaces are coated with the New OG550 coating, which enhances its longpass filtering capabilities. This coating ensures high transmission of light at wavelengths shorter than 550 nm and efficient absorption of longer wavelengths.
The FSQ-OG550 filter is designed in the shape of a thin lens, which can be beneficial in certain optical configurations. It is currently in stock and available for immediate purchase through the Newport website.
