578DIN25 25 mm Dia. Narrowband Interference Bandpass Filter 577.7nm
The 578DIN25 is a 25 mm diameter narrowband interference bandpass filter, specifically designed to isolate the 577.7nm wavelength. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the bandpass type, which means it allows a specific range of wavelengths to pass through while blocking out others. In this case, the passband ranges from 576.2nm to 579.2nm, with the center wavelength at 577.7nm. This makes it ideal for applications that require precise wavelength selection, such as fluorescence microscopy, spectroscopy, or laser systems.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a circular base shape and a thin lens shape, with a thickness of 6.1mm. This thin design not only reduces weight but also minimizes optical aberrations.
The front and back surfaces of the filter are coated with KNI 578DIN, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflections and increasing transmission.
The filter is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the item data.
