87-047 25.2 x 35.6 mm Dichroic Longpass Filter; t=1.05mm 1050nm

The 87-047 Dichroic Longpass Filter is a high-quality optical component sourced from Edmund Optics. This filter is designed to selectively transmit light with wavelengths above 1050nm while reflecting or absorbing shorter wavelengths. The dichroic coating on both the front and back surfaces ensures efficient light manipulation, making it an ideal choice for various applications in photonics and optics research.

The filter boasts a rectangular shape with dimensions of 25.2mm in width and 35.6mm in height, providing ample area for beam manipulation. With a thickness of 1.05mm, it is designed to maintain minimal optical distortion while offering sufficient mechanical robustness. The filter is made from UVFS material, identified as "mal- 1965" in the item data, ensuring reliable performance across a broad spectral range.

The 87-047 filter features a cut-on wavelength of 1050nm, meaning it begins to transmit light at this wavelength and above. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths below 1050nm. This specific wavelength range makes it suitable for various applications, such as infrared spectroscopy, bioimaging, and other research fields where long-wavelength light manipulation is required.
