69-877 12.5 x 17.6 mm Dichroic Longpass Filter; t=1.05mm 500nm

This is a 12.5 x 17.6 mm Dichroic Longpass Filter, model number 69-877, sourced from the renowned optical components vendor, Edmund Optics. The filter is designed to transmit light at wavelengths above 500nm, making it suitable for a wide range of applications where longpass filtering is required.

The filter is constructed with a rectangular base shape and a thickness of 1.05mm, providing durability and stability. It features a dichroic coating on both the front and back surfaces, identified as EDM 69-866, which is designed to reflect or transmit light based on its wavelength. This coating ensures efficient filtering and maintains the integrity of the transmitted light.

The physical data of the filter indicates a cut-on wavelength of 500nm, meaning it starts to transmit light at this wavelength. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths above 500nm. This makes it a versatile tool for various optical setups.

The filter is available in a thin lens shape, which is beneficial for applications where space is a constraint. It is currently in stock and can be purchased directly from the vendor's website using the provided weblink.
