620FIB50 50 mm Dia. Standard Interference Bandpass Filter 620nm

Knight Optical's 620FIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 620nm range while blocking light at other wavelengths. This filter is a crucial component for applications that require narrowband light transmission, such as fluorescence microscopy, spectroscopy, and laser systems.

The filter is made from UVFS Mal-1965, a high-quality optical material known for its excellent transmission characteristics and durability. It features a circular shape, a thickness of 6.1mm, and a thin lens shape, making it compatible with a wide range of optical systems.

The 620FIB50 has a cut-on wavelength of 615nm and a cut-off wavelength of 625nm, ensuring a tight bandpass around the central wavelength of 620nm. This is particularly useful in applications where stray light can cause unwanted noise or interference.

The filter is coated with KNI 620DIB on both the front and back surfaces, providing enhanced durability and resistance to environmental factors. This coating also helps to reduce surface reflections, improving the overall transmission efficiency of the filter.
