84-782 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 450nm

The 84-782 is a Bandpass Filter, sourced from the reputable optical components vendor, Edmund Optics. This particular filter has a circular base shape with a diameter of 25 mm and a thickness of 3.5 mm, making it suitable for a wide range of applications. The filter is designed to transmit light within a specific wavelength range, while blocking other wavelengths, making it an essential component in various optical systems.

The 84-782 filter is characterized by a center wavelength (CWL) of 450nm, which is the wavelength at which the filter has its maximum transmittance. The filter's cut-on wavelength is 425nm, and the cut-off wavelength is 475nm. This means that the filter starts transmitting at 425nm and stops transmitting at 475nm, effectively passing light in the 450nm range.

The filter is made from UVFS Mal-1965 material, a detail that can be crucial for certain applications. It also features hard coating on both the front and back, enhancing its durability and resistance to wear and tear. The coating type is EDM 84-770, which is a high-quality coating known for its performance and reliability.

The 84-782 filter has a thin lens shape, which can be beneficial in applications where space is a constraint. The filter's physical data, including its wavelength and geometry, make it a versatile component that can be used in various optical systems.

In terms of availability, the 84-782 filter is currently in stock, according to the vendor's website. The filter's catalog number is 84-782, and it can be found on the Edmund Optics website at https://www.edmundoptics.com/p/450nm-cwl-25mm-dia-hard-coated-od-4-50nm-bandpass-filter/27851/.
