DMSP1500T Dia:0.5in Shortpass Dichroic Mirror; 1500 nm Cut-On

The DMSP1500T is a dichroic mirror, a type of optical element that selectively reflects or transmits light based on its wavelength. This particular model, sourced from Thorlabs, is designed with a shortpass characteristic, allowing it to reflect shorter wavelengths while transmitting longer ones. The cut-on wavelength is 1500 nm, meaning it begins to transmit at this point and beyond.

The mirror has a circular base shape with a diameter of 12.7 mm and a thickness of 3.2 mm, making it compact and versatile for various optical setups. It is made from UVFS material, identified as MAL-1965 in the vendor's catalog. The coating on the front surface is 'tho dmsp1500', specifically designed to achieve the shortpass dichroic properties.

The DMSP1500T is available directly from Thorlabs and is currently in stock, according to the vendor's website. This mirror, like other optical elements, is shaped as a thin lens, contributing to its ease of integration into optical systems.
