FSQ-U340 50.8 x 50.8 mm Visible Absorbing UV Bandpass Filter 340nm

The FSQ-U340 is a high-quality Bandpass Filter, sourced from the reputable vendor MKS/Newport. This filter is specifically designed for use in applications that require precise wavelength selection within the ultraviolet (UV) spectrum.

The FSQ-U340 has a center wavelength (CWL) of 340nm, making it ideal for use in UV detection and analysis. The filter is rectangular in shape, with a width and height of 50.8mm each, providing a substantial surface area for effective light filtration. It has a thickness of 3mm, ensuring durability and stability during operation.

The filter's coating is a notable feature. Both the front and back surfaces are coated with the new FSQ-U340 coating, which is designed to enhance the filter's performance and longevity. This coating aids in the absorption of unwanted UV light, allowing only the specified wavelength to pass through.

The FSQ-U340's geometry and shape further contribute to its functionality. It features a Thin Lens shape, which is beneficial in applications where space is a constraint. The filter's physical data, including its CWL, are carefully controlled during manufacturing to ensure consistent performance.
