84-123 50 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 832nm

The 84-123 is a 50 mm diameter Bandpass Filter, specifically designed for fluorescence applications, with a center wavelength of 832nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase through their website. The filter is currently in stock, ensuring quick delivery for your optical project needs.

The Bandpass Filter is a crucial component in optical systems, allowing light within a specific wavelength range to pass through while blocking out other wavelengths. This particular filter has a cut-on wavelength of 809.5nm and a cut-off wavelength of 854.5nm, making it ideal for applications that require the precise filtering of light around the 832nm wavelength.

The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. It has a circular shape, a standard in optical systems due to its ease of alignment and integration. The filter's thickness is 2mm, providing sufficient structural integrity while minimizing unwanted optical effects.

The filter's coatings are another notable feature. Both the front and back surfaces are coated with EDM 84-091, a hard coating that enhances the filter's durability and resistance to wear and tear. This coating also helps to reduce surface reflections, improving the overall efficiency and performance of the optical system.

The filter's geometry is that of a Thin Lens, a design that minimizes optical aberrations and distortions, ensuring the highest quality light transmission. This makes the 84-123 an excellent choice for applications that require precise, high-quality light filtering.
