The DMLP505L Dia:2in Longpass Dichroic Mirror is a high-quality optical component manufactured by Thorlabs, a leading vendor in the field of optical elements. This mirror is designed with a longpass dichroic coating, which allows it to reflect light with wavelengths shorter than the specified cut-on wavelength and transmit light with wavelengths longer than the cut-on. In this case, the cut-on wavelength is 505 nm.
This mirror is circular in shape, with a diameter of 50.8 mm and a thickness of 5 mm, making it suitable for a wide range of optical applications. The mirror is made from UVFS material, identified as MAL-1965 in Thorlabs' catalog. The coating on the front surface of the mirror is THODMLP505, which is specifically designed to provide the longpass dichroic functionality.
The mirror is designed with a thin lens shape, which can provide additional functionality in certain optical systems.
