DMLP1800T Dia:0.5in Longpass Dichroic Mirror; 1800 nm Cut-On

The DMLP1800T is a high-quality dichroic mirror, part of the extensive optical components catalog offered by Thorlabs. This circular mirror, with a diameter of 12.7 mm and a thickness of 3.2 mm, is designed for use in a variety of optical systems.

The mirror's primary function is to reflect light of a certain wavelength while transmitting light of other wavelengths. In the case of the DMLP1800T, it has a longpass characteristic, meaning it reflects wavelengths shorter than 1800 nm and transmits wavelengths longer than 1800 nm. This makes it ideal for applications where the goal is to separate infrared light from other parts of the spectrum.

The mirror's coating is a key factor in its performance. The front surface of the DMLP1800T is coated with a specialized dichroic coating, identified as 'tho dmlp1800'. This coating is specifically designed to provide the mirror with its longpass characteristics.

The mirror's shape is described as a 'Thin Lens', suggesting that it may have some focusing or diverging properties. However, the specifics of these properties are not detailed in the provided data.

In terms of availability, the DMLP1800T is currently in stock, according to the vendor's website. Further information and technical specifications can be found on the product page, linked below.
