850FIR12 12.5 mm Dia. Broadband Interference Bandpass Filter 850nm
The 850FIR12 is a high-quality bandpass filter, designed and manufactured by Knight Optical, a leading vendor in the optical industry. This filter is specifically engineered for use in broadband applications, with a center wavelength of 850nm.
The filter is circular in shape, with a diameter of 12.5mm and a thickness of 6.1mm, making it a compact yet robust solution for various optical systems. The base material of the filter is UVFS Mal- 1965, a material known for its excellent optical properties and durability.
The 850FIR12 features a cut-on wavelength of 830nm and a cut-off wavelength of 870nm, providing a narrow and precise passband. This characteristic is crucial in applications where controlling the spectral range is paramount. The filter's coating, KNI 850DIR, is applied on both the front and back surfaces, enhancing its performance and longevity.
The filter's geometry is designed in a Thin Lens shape, which not only contributes to its compactness but also allows for easy integration into existing optical systems. The 850FIR12 is currently in stock and available for immediate purchase through the vendor's website.
