780FIR12 12.5 mm Dia. Broadband Interference Bandpass Filter 780nm
Knight Optical's 780FIR12 is a high-quality bandpass filter designed for use in optical systems that require narrowband transmission at the 780nm wavelength. This filter is fabricated from UVFS Mal-1965, a material known for its excellent optical properties and durability.
The filter has a circular shape with a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for a wide range of applications. The base shape is a thin lens, which contributes to its compact design and ease of integration into optical systems.
The 780FIR12 features a broadband interference bandpass design, with a cut-on wavelength of 765nm and a cut-off wavelength of 795nm. This design ensures a high transmission coefficient within the passband and a sharp roll-off outside the passband, reducing unwanted stray light and improving overall system performance.
The filter is coated with KNI 780DIR on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and improving transmission. It also provides excellent environmental stability, ensuring the filter maintains its performance over time.
Knight Optical's 780FIR12 is currently in stock and available for immediate delivery. For more information, including detailed specifications and pricing, please refer to the weblink provided.
