500FIR25 25 mm Dia. Broadband Interference Bandpass Filter 500nm

The 500FIR25 is a high-quality bandpass filter, designed and manufactured by Knight Optical, a leading provider of optical components. This filter, with a catalog number 500FIR25, is specifically engineered for use in systems that require narrowband transmission at 500nm, while effectively suppressing out-of-band wavelengths.

The filter boasts a circular shape, with a diameter of 25mm and a thickness of 6.1mm, making it compatible with a wide range of optical systems. The base material for this filter is UVFS Mal-1965, a material known for its excellent optical properties and durability.

The 500FIR25 filter is designed with a cut-on wavelength of 480nm and a cut-off wavelength of 520nm, ensuring a tight transmission window around the central wavelength of 500nm. This is particularly useful in applications where stray light or unwanted spectral components need to be minimized.

The filter is coated with KNI 500DIR on both the front and back surfaces, a coating that enhances its performance and durability. The shape of the filter is thin lens, which is beneficial in systems where compactness and minimal optical path differences are important.

According to the vendor, this filter is currently in stock and available for immediate shipping. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
