DMSP1500L Dia:2in Shortpass Dichroic Mirror; 1500 nm Cut-On

The DMSP1500L 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 transmit wavelengths shorter than the specified cut-on wavelength while reflecting longer wavelengths.

The DMSP1500L has a cut-on wavelength of 1500 nm, making it ideal for applications where light in the near-infrared region needs to be isolated or manipulated. Its circular geometry, with a diameter of 2 inches (50.8 mm), is versatile and compatible with a wide range of optical systems. The mirror has a thickness of 5 mm, providing sufficient structural integrity while maintaining a low profile.

The mirror's coating is another crucial aspect of its design. The front surface is coated with a specialized dichroic coating, denoted as 'tho dmsp1500'. This coating ensures the mirror's shortpass characteristics, enabling it to perform as expected in its intended application.

The DMSP1500L is designed in the shape of a thin lens, suggesting that it may have some focusing capabilities, although this is not explicitly stated in the provided data. However, this shape does imply that the mirror is designed to be used in conjunction with other optical elements, contributing to a larger optical system.
