042-7770SB 25.4 mm Dia. 70:30 (R:T) UVFS Femtoline Broadband Laser Beamsplitter; t=3mm 720-880nm

The 042-7770SB is a broadband laser beamsplitter from EKSMA Optics, designed for use in femtoline components. This beamsplitter boasts a circular diameter of 25.4 mm and a thickness of 3 mm, making it a robust and compact option for various applications.

The beamsplitter's primary function is to divide an incoming light beam into two separate beams. In this case, the 042-7770SB has a 70:30 (R:T) ratio, meaning that 70% of the incoming light is reflected, while 30% is transmitted. This specific model is designed for use with wavelengths between 720 and 880 nm, making it suitable for a wide range of laser applications.

The beamsplitter's coating, EKS 042-7770SB, is applied to the front surface. This coating enhances the beamsplitter's performance, ensuring optimal reflection and transmission rates within the specified wavelength range.

The 042-7770SB is a thin lens beamsplitter, which means it is designed to be as thin as possible while still maintaining its functionality. This makes it an excellent choice for applications where space is at a premium.
