DMLP1800L Dia:2in Longpass Dichroic Mirror; 1800 nm Cut-On

The DMLP1800L is a dichroic mirror offered by Thorlabs, designed with a circular geometry and a diameter of 2 inches (50.8 mm). This mirror is part of the DMLP series, which is known for its longpass dichroic characteristics. The mirror's primary function is to reflect shorter wavelengths and transmit longer wavelengths, making it ideal for applications that require the separation of different wavelength bands.

The DMLP1800L has a specified cut-on wavelength of 1800 nm, meaning it begins to significantly transmit light at this wavelength while reflecting shorter wavelengths. This property makes it suitable for use in applications involving infrared (IR) light. The mirror has a thickness of 5 mm, providing sufficient structural integrity for most optical setups.

The mirror's coating is a crucial component of its functionality. The front surface of the DMLP1800L is coated with a specialized dichroic coating, denoted as 'tho dmlp1800'. This coating is designed to provide the mirror with its longpass dichroic properties.

The mirror is available in a 'Thin Lens' shape, which refers to the mirror's overall design and construction. This shape ensures the mirror fits seamlessly into various optical systems and configurations.
