780DIR12 12.5 mm Dia. Broadband Interference Bandpass Filter 780nm

The 780DIR12 is a high-quality broadband interference bandpass filter, designed and manufactured by Knight Optical. This filter is specifically engineered to transmit light within the 780nm wavelength range while effectively blocking unwanted light outside this range.

The filter boasts a circular shape with a diameter of 12.5mm and a thickness of 6.1mm, making it compatible with a wide range of optical systems. The base material of the filter is UVFS Mal- 1965, a robust and reliable material known for its optical properties.

The 780DIR12 filter features a cut-on wavelength of 765nm and a cut-off wavelength of 795nm, ensuring a tight and precise passband around the central wavelength of 780nm. This characteristic is particularly useful in applications where narrowband light is required, such as in spectroscopy, fluorescence microscopy, or any other application where specific wavelength selection is critical.

The filter is coated with KNI 780DIR on both the front and back surfaces, enhancing its performance and durability. This coating provides excellent environmental stability, making the filter suitable for use in various conditions. The filter's shape is thin lens, which is beneficial in applications where minimal thickness is required.
