DMSP740B 35 mm x 52 mm Multi-Band Dichroic Mirror; 740/1080 nm Cutoff; 1020 nm Cut-On

The DMSP740B is a high-quality dichroic mirror from Thorlabs, designed with a rectangular base shape and dimensions of 35 mm in height and 52 mm in width. This mirror is part of the UVFS MAL-1965 material category and features a thin lens shape, making it suitable for a wide range of optical applications.

The DMSP740B is specifically designed for multi-band use, with a 740 nm cutoff and a 1020 nm cut-on. This means it reflects wavelengths shorter than 740 nm and transmits wavelengths longer than 1020 nm, while allowing wavelengths between 740 nm and 1020 nm to pass through. This makes it an ideal component for applications involving multiple wavelengths, such as fluorescence microscopy or multi-spectral imaging.

The mirror's coating is another notable feature. The front surface is coated with a specialized Thorlabs DMSP740 coating, which enhances its performance in specific wavelength ranges. This coating ensures high reflectivity for the reflected wavelengths and high transmissivity for the transmitted wavelengths, contributing to the overall efficiency and effectiveness of the optical system.

The DMSP740B is currently in stock and available for immediate purchase through the Thorlabs website, as indicated by its "Valid - in stock" weblink status. With its combination of multi-band capabilities, specialized coating, and high-quality construction, the DMSP740B is a versatile and reliable choice for a wide range of optical applications.
