86-990 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 370nm

The 86-990 is a 50 mm diameter Bandpass Filter, specifically designed for fluorescence applications, with a center wavelength of 370nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry. The filter is characterized by its high transmission at the center wavelength and its sharp cut-on and cut-off characteristics, which help to isolate the desired spectral band.

The filter has a diameter of 50 mm and a thickness of 2 mm, making it suitable for a wide range of applications. The cut-on wavelength is 350nm, and the cut-off wavelength is 390nm, providing a narrow bandwidth of 36nm. This ensures that only the desired wavelengths are transmitted, reducing noise and improving signal-to-noise ratio.

The 86-990 filter features a hard coating on both the front and back surfaces, which provides excellent durability and resistance to environmental factors. The coating also enhances the filter's performance by reducing surface reflections and increasing transmission.

The filter's geometry is defined by a Thin Lens shape, which is designed to minimize optical aberrations and ensure high-quality imaging. The filter is currently in stock and available for immediate shipping, as indicated by its weblink status.
