86-981 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 357nm

The 86-981 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter boasts a 25 mm diameter and a thickness of 2 mm, making it a robust and compact solution for various optical setups.

The filter is designed to transmit light within a specific wavelength range, with a Center Wavelength (CWL) of 357nm. This means it allows light around this wavelength to pass through while blocking other wavelengths. The filter's Cut-on and Cut-off wavelengths are 333nm and 381nm respectively, further defining its passband.

The 86-981 filter features Hard Coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also helps to reduce surface reflections, improving overall transmission and contrast in the system.

The filter's geometry is defined by its Thin Lens shape, which is designed to minimize optical aberrations and distortions. This makes it an ideal choice for applications that require high-precision optical performance.

The filter is currently in stock and available for purchase through the Edmund Optics website. Detailed specifications, including CWL, diameter, thickness, and coating, can be found in the item data provided.
