DMLP638R 25 mm x 36 mm Longpass Dichroic Mirror; 638 nm Cut-On

The DMLP638R is a 25 mm x 36 mm rectangular dichroic mirror, sourced from the reputable vendor Thorlabs. This mirror is designed with a longpass characteristic, featuring a 638 nm cut-on wavelength, making it ideal for applications that require the separation of longer wavelengths from shorter ones.

The mirror's geometry is defined by a width of 36 mm, a height of 25 mm, and a thickness of 1 mm, giving it a thin lens shape. This mirror is made from UVFS material, identified as MAL-1965, which is known for its durability and optical quality.

The coating on the front surface of the mirror is identified as 'tho dmlp638'. This coating is specifically designed to enhance the mirror's performance at the specified cut-on wavelength. The mirror's 'Thin Lens' shape further optimizes its performance in optical systems.
