FSR-BG3 25.4 mm Dia. Colored Glass Absorptive Bandpass Filter 356nm

The FSR-BG3 is a high-quality Bandpass Filter, designed and manufactured by MKS/Newport. This filter is specifically engineered for use in applications that demand precise wavelength selection and rejection of unwanted spectral regions. The FSR-BG3 boasts a center wavelength of 356nm, making it ideal for use in ultraviolet (UV) applications.

The filter is designed with a circular geometry, featuring a diameter of 25.4mm and a thickness of 3mm. This compact yet robust design ensures ease of integration into various optical systems while providing reliable performance. The FSR-BG3 is cut on at 283nm and cut off at 429nm, further enhancing its spectral selectivity.

The FSR-BG3 is coated with a specialized Newport coating on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The coating also provides excellent environmental stability, ensuring the filter maintains its performance characteristics over time.

The filter's shape is that of a Thin Lens, which not only aids in light focusing but also reduces the risk of optical aberrations. This feature makes the FSR-BG3 a versatile choice for a wide range of UV applications.
