BLP01-458R-25 25 mm Dia. 441.6 and 457.9nm EdgeBasic best-value Long-Pass Edge Filter by Semrock

Semrock's BLP01-458R-25 is a Long-Pass Edge Filter, designed with a circular shape and a diameter of 25 mm. This filter is a crucial component in various optical systems, particularly those requiring wavelength discrimination.

The filter's primary function is to allow transmission of light above a specified wavelength while blocking or reflecting light of shorter wavelengths. In this case, the BLP01-458R-25 is designed to cut on at 458 nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength, which is the point at which the filter starts to block light, is 0 nm for this particular model.

The filter is constructed with a thickness of 2 mm and features Semrock's EdgeBasic coating on both the front and back surfaces. This coating enhances the filter's performance, ensuring efficient light transmission and blocking.

The BLP01-458R-25 is made from UVFS Mal-1965, a material known for its optical properties and durability. The filter's thin lens shape further contributes to its performance, ensuring minimal distortion and loss of light.
